#### **Abstract**

The impact of the 4th industrial revolution, or Industry 4.0, has generated innovations that help industrial automation, promoting the digitization of activities and processes that result in increased productivity, competitiveness, improved quality of products created, and increased capacity for companies to invoke through the use of technologies such as smart cities, energy, oil and gas, Internet of things, digital and auditory manufacturing, digital twins and systems integration, among the most diverse areas inserted in Industry 4.0. This chapter will present a summary of how the most diverse industry sectors such as smart cities, oil, gas sector, energy and other areas are applying digital twins as a tool to support the digitization of companies.

**Keywords:** digital twins, industry 4.0, smart cities, oil and gas, energy, opportunity, applicability

#### **1. Introduction**

The concept of digital twins, originated by NASA, emerged in 2012 when it became necessary to create virtual environments that corresponded to the data of physical objects, assisting the company in decision-making [1].

Based on the article developed by Dashkina et al. [2], it is identified that Industry 4.0 is strongly linked to digital twin technology, which corresponds to the particularity of linking the behavior of physical objects such as manufacturing lines, robots, and technical installations through the use of computers and software. The use of the digital twins concept is particularly relevant when it involves mechanical parts where their properties undergo physical wear and tear over time or even cracks in metal components. It is suggested to create monitoring routines for these components with the aim of creating process improvements through continuous feedback on the state of the parts.

Canedo [3] mentions that representing real objects in digital twins adds great value compared to local optimization as is done today. Optimization and efficiency are gains to be noted when using digital twins at the system-of-systems level, and according to the article [4], the use of digital twins is a significant factor in decisionmaking to positively impact product construction.

According to Pethuru and Preetha [5], through real data of objects, it is possible to create simulations that assist in predicting how physical objects will be affected based on the received data. In other words, constructing monitoring of physical objects in

a controlled virtual area, it helps in the prevention and control of possible failures encountered during the use of real objects [1].

The power of using digital twins in Industry 4.0 can be explored in various areas such as IoT, smart cities, energy, oil and gas, and healthcare as a decision-making tool to assist in the continuous improvement of the process of building a sustainable business model.

#### **2. Industry 4.0 and digital twins in the sectors**

In this section, we will explore how digital twins are being applied in Industry 4.0 in the energy, oil and gas, smart cities sectors, and other areas.

#### **2.1 Energy sector**

Through research conducted in article [6] by Arowoiya, it was observed that the applicability of digital twins (DT) in the energy sector can assist in energy management, usage, and simulation creation in conjunction with real-world data [7–9] to predict potential issues found in buildings.

Another application of DT in the energy sector is related to temperature control in physical environments, where a large number of variables were manually controlled using thermometers, hydrometers, and anemometers as input for manual decisionmaking [6]. To address this issue, Escandón et al. [10] mentions the use of a neural intelligence network in conjunction with DT.

Simultaneously, to address the monitoring issue in buildings, ref. [6] cites article [11] that uses DT in conjunction with the creation of an integrated building information modeling (BIM) system with IoT, which sends alerts to operators, thus assisting in real-time monitoring of physical objects.

The increasing interest in academia and the industry regarding the use of DT in the energy sector stems from the possibility of real-time monitoring of an electrical network with the assistance of IoT and AI.

The energy sector can explore the creation of simulation software to assess the wear, performance, and associated costs of using specific equipment for energy production, whether on a small or large scale, by utilizing a cluster of computers.

#### **2.2 Oil and gas sector**

For ref. [12], the major risk of oil and gas extraction up to the platforms is extremely complex and risky, with the possibility of setbacks that can result in financial and catastrophic losses. It is necessary for the industry to take preventive measures to mitigate the risks.

With this issue, it is important for companies in the field to invest in technology and innovation in order to expand oil and gas extraction while mitigating the inherent risks of the circumstances. In the article [13], the author states that there are thousands of sensors, complex components, and processes to be followed, and Digital Twins (DT) can be used to assist the oil and gas sector in risk mitigation through predictive analysis of the data exposed by real objects.

In ref. [12], it is mentioned that DT can help the oil and gas sector by creating virtual environments with real data that assist administrators in testing deviations, recording and analyzing data, and advancing with the security of the business cycle. *How Digital Twins Is Being Used in Industry 4.0 DOI: http://dx.doi.org/10.5772/intechopen.113060*

By using the virtual environment with real-time data from real objects, DT can perform routines following a predefined process in conjunction with the assistance of AI to identify potential anomalies predictively, helping the process become increasingly secure and scalable.

One way to obtain data from oil and gas platforms, according to Priyanka et al. [12], is through the use of smart IoT modules that are installed between sensors and control points using the Routing Protocol for Lossy organizations (RPL) protocol, which will help make oil and gas extraction safer through predictive information. Additionally, according to Wanasinghe et al. [14], it helps the platform operator visualize risks in a centralized visual manner, which can aid in intervening in potential issues.

In **Figure 1** [14], it is mentioned that there are several frameworks developed for DT where a significant portion converges to include three major sections. The physical section includes accessories, sensors, and actuators. The virtual section includes multi-physics spaces, model simulations that contribute to data analysis, and finally, the connection between the physical and virtual spaces, which ensures the exchange of information between the two.

Another approach, according to Wanasinghe et al. [14], would be to create a DT framework using a five-component model, as shown in **Figure 2**. The physical environment contains all the physical accessories, sensors, and actuators. The virtual space contains a mirror of the physical environment for high fidelity in creating simulations. The service system contains another enterprise application responsible for service visualizations, service quality, diagnostic services, model calibration, algorithm services, and other services. The DT data fusion acts as a bridge between the physical environment, virtual model, and service system.

According to Wanasinghe et al. [14], the use of machine learning, deep learning, and artificial intelligence with intelligent mathematical algorithms will be important tools in the predictive evaluation of possible risks associated with the components used on platforms, thereby avoiding potential failures and accidents.

The oil and gas sector can explore simulation programs that can be created using real data and characteristics of the components, especially the variables of the environment that are part of the oil extraction process, to assist in the predictive identification of wear and tear through the use of mathematical models that help the company mitigate risks, costs, environmental problems, and assist in the scheduled replacement of components. In this context, it is relevant for the company to create scalable solutions in machine clusters due to the possibility of a high level of data processing that may be generated during the prediction process.

Wanasinghe et al. [14] mentions that simulations using DT will assist engineers in building new platforms or modifying their oil and gas extraction structures, reducing risks, as this step can be repeated whenever necessary to bring greater reliability, performance, and reduction of unnecessary costs before executing the operation.

Wanasinghe et al. [14] observed that DT can help engineers and individuals involved in problem-solving in a faster and cooperative way by obtaining real-time information from the platforms, enabling the creation of virtual rooms with the possibility of simulations to improve performance in critical decision-making for any occurring problems.

Another factor where DT can help in the oil and gas sector, according to Wanasinghe et al. [14], is the creation of training centers in conjunction with the use of VR, AR, and MR technologies to train new employees who can navigate within oil and gas centers with ease of operating equipment, inspecting systems, and interacting with ongoing operations. This is a significant factor for companies to explore this possibility since, according to research in articles [15–16], the oil and gas sector is facing a challenge called the "big-crew change," where in the near future, more than 50% of experienced workers will retire, causing the sector to lose skills and talents in the industry.

#### **2.3 Smart cities sector**

According to Zhuang et al. [17], the characteristics of Digital Twins (DT), such as the integration of various types of data from physical objects, involvement throughout the lifecycle of physical objects, co-evolution with them, and continuously

*How Digital Twins Is Being Used in Industry 4.0 DOI: http://dx.doi.org/10.5772/intechopen.113060*

accumulating relevant knowledge, can help the government [18] create more predictive and comprehensive prediction and indicators in a smart cities ecosystem.

In the field of smart cities, DT, as mentioned in ref. [17], can be used to build physical maps of the real city in a virtual area that receives real-time events from the mapped objects. This allows for transferring, modifying, deleting, and performing operations in a city area through the created 3D models, while checking for possible problems that may occur through these operations.

Mohammadi and Taylor [19] mentions a project being developed using DT concepts in smart cities called the Digital Twin City of Atlanta, which utilizes a VR platform developed with Unity, a cross-platform framework designed for video games. This environment helps discover interactions and interoperability of its human infrastructure systems.

According to Ivanov et al. [20], DT can bring opportunities for improvements in smart cities through observability of resident traffic flow, private business traffic, public transportation, and real-time information from private and public intelligent sensors that help monitor and analyze temperature and humidity as shown in **Figure 3**.

According to Ivanov et al. [20], through the collected data in a smart city, the following opportunities for improvements can be generated along with the use of IoT:

• Creating a DT of the public transportation network to monitor and predict possible availability and efficiency situations of transportation.


To analyze the large amount of data received by sensors in a smart city within a DT, it is necessary, as stated in ref. [21], to include statistics, data analysis intelligence, and a computational model.

Ivanov et al. [20] states the need to create a large warehouse that can handle a significant amount of data, sufficient bandwidth to collect and analyze the data received, and computational power to support the high degree of processing that can be done through techniques such as machine learning.

#### **2.4 Other areas**

This section aims to show how some other areas are exploring digital twins in various sectors.

In the article [22], it is mentioned that the manufacturing industry has been using DT through monitoring, simulations, and remote control of physical assets using virtual objects. This, in turn, helps in understanding and improving customer satisfaction by enhancing existing products, operations, and services.

Also, in the same article [22], in the field of agriculture, it is possible to use DT by creating virtual environments representing a farm with the goal of increasing productivity and production efficiency while reducing energy and costs.

Regarding education and training, Attaran and Celik [22] explains that the use of DT through Virtual Reality (VR) has been assisting in the training of doctors by complementing and refining the traditional educational model.

#### **3. Discussion**

In this chapter, which focused on the study in the areas of oil and gas, energy, smart cities, and other general fields, the observation was made on how the industry has been using DT (Data Technology) to enhance process quality through the following main characteristics.

#### **3.1 Usage of real data in virtual environments**

The use of real data is connected and directly utilized in a virtual environment, thereby assisting in the creation of simulations that aid in better decision-making.

#### **3.2 Virtual reality (VR)**

The use of virtual reality has aided in the development of more effective training and improved interactions with real objects in a virtual world.

#### **3.3 Monitoring**

Real-time monitoring of physical objects in a virtual environment will help in predicting potential issues through the use of IA.

### **4. Conclusion**

In Industry 4.0, one of the pillars being explored in the industry is Digital Twins. This work aimed to demonstrate how Digital Twins are being used in the sectors of smart cities, energy, oil and gas, and other areas, and how they have helped in reducing risks, and costs, improving processes, and enabling real-time monitoring of physical objects through the use of the Internet of Things and artificial intelligence.

#### **1. Introduction**

Within the realm of management sciences, it is of paramount importance a comprehensive understanding of the substantial distinctions that exist between projects and operations [1]. On the one hand, operational activities refer to the ongoing and repetitive tasks that are essential to sustain a business [2]. On the other hand, projects are temporary endeavors that are undertaken with the aim of achieving specific objectives [3]. As an illustration, the duty of overseeing a manufacturing facility can be characterized as an intricate operation, with the primary objective of ensuring a steady output of goods and services that meet the highest standards of excellence. In contrast, the endeavor of building a new manufacturing facility would entail a set of well-defined objectives, such as accomplishing the construction phase within the stipulated time frame and with the allocated financial resources. The significance of this differentiation lies in the fact that each of these two entities demands distinct management methodologies, instruments, and practices.

The practice of project management entails the systematic planning, meticulous organization, and efficient allocation of resources toward the attainment of predetermined objectives within well-defined limitations [4]. Project management involves a comprehensive spectrum of tasks, spanning from the conception and planning phase to the implementation, monitoring, and conclusion. The efficacy of project management is contingent upon its capacity to execute projects punctually, within financial constraints, and with the intended level of excellence [5]. The classical methodology for project management is characterized by a predictive orientation, whereby the project plan is formulated in advance and adhered to throughout the entire project duration. This particular methodology presupposes that the prerequisites of the project are comprehensively comprehended and can be precisely delineated prior to project execution. Furthermore, it assumes that the project team possesses the essential expertise and resources to execute the project effectively. Nonetheless, it is imperative to note that this particular methodology may not be appropriate for endeavors that are complex or ambiguous or that necessitate a substantial level of inventiveness [6].

The agile project management (APM) approach has surfaced as a means of managing projects in a more flexible and adaptive manner and has garnered significant traction across diverse industries [7, 8]. In the realm of project management, the concept of agility pertains to the capacity to react promptly and adeptly to alterations in project specifications, stakeholder demands, and market fluctuations [9]. APM is an approach that prioritizes iterative and adaptable processes, with a strong emphasis on collaboration and continuous improvement. This approach is designed to enable teams to respond quickly and effectively to changing circumstances and to maintain a focus on delivering high-quality results. By fostering a culture of flexibility and open communication, APM can help organizations achieve their goals more efficiently and effectively [10].

In contrast to classical project management methodologies that adhere to a linear and sequential approach, APM fosters adaptability and promotes regular feedback and iteration. As APM continues to gain ground across various industries, another technology that is becoming popular is the digital twin (DT), a computer-generated replica of a tangible entity, operation, or framework. This cutting-edge technology enables the creation of a virtual model that mirrors the real-world counterpart, allowing for the simulation of various scenarios and the analysis of data in a controlled environment. In contrast to conventional computer-aided design, this innovative approach integrates real-time data, simulation, and analytics to generate a comprehensive model that emulates the behavior and attributes of the corresponding physical entity [11].

The concept of DT has garnered significant attention in recent times and has emerged as a transformative trend for various industries, much like APM did in the past. DTs serve as dynamic reflections of physical systems, facilitating ongoing monitoring, simulation, and analysis. The information gathered from the physical system is harmoniously integrated with the DT, furnishing invaluable discernments for decision-making and optimization [12]. DT technology offers a multitude of benefits for diverse industries, enabling them to engage in virtual prototyping and predictive maintenance and optimize performance. As the potential of DT technology has become increasingly apparent, organizations have begun to incorporate it into their overall project management strategies [13]. Through the development of a virtual representation of the project's end product, teams can acquire a more comprehensive understanding of the system's behavior, proactively anticipate and resolve potential issues, and optimize the overall outcomes of the project [11, 14]. Projects are inherently complex and pose numerous challenges that can be effectively addressed

#### *Perspective Chapter: Digital Twin Technology as a Tool to Enhance the Performance of Agile… DOI: http://dx.doi.org/10.5772/intechopen.112489*

through the use of DT technology. This innovative approach can significantly enhance decision-making processes, facilitate the seamless transmission of critical information, and improve risk mitigation strategies. By leveraging the power of DT technology, project stakeholders can achieve greater efficiency, accuracy, and overall success in their endeavors.

Among the plethora of proposed APM methodologies, Scrum has emerged as the preferred approach for most cases and has gained widespread adoption because of its effectiveness in managing complex and dynamic projects [15]. Scrum is a highly effective iterative framework that is designed to deliver incremental value through a series of short development cycles, which are commonly referred to as sprints. This approach is widely recognized for its ability to enhance productivity, improve collaboration, and foster a culture of continuous improvement [16]. By leveraging the Scrum methodology, organizations can achieve greater agility and responsiveness and ensure that their products and services are delivered to market in a timely and efficient manner.

In this chapter, we will delve into the intricacies of DT technology within the realm of APM, with a particular emphasis on Scrum projects. Readers will acquire invaluable insights from this chapter on how to leverage the potential of DT technology effectively in the context of APM.

We have structured this chapter in the following manner: Section 2 provides an in-depth exploration of the fundamental principles of APM, including its unique characteristics. In Section 3, the focus shifts to the practical aspects of project and product development, with a particular emphasis on the distinctions between software and hardware development. This section also addresses the challenges inherent in implementing APM in software development. Finally, in Section 4, we present DT technology as a viable solution to many of the challenges encountered in physical product development within the APM framework. This section provides a comprehensive discussion of how the DT can be successfully implemented as well as its numerous advantages, making it an indispensable tool for physical product projects within the APM paradigm.

#### **2. Agile project management**

The genesis of the APM can be traced back to the 1990s, a time when software development teams were searching for alternative project management approaches to the conventional ones [17]. Numerous industries expressed their displeasure with the inflexible and step-by-step approach of the traditional waterfall methodology [18]. It is imperative for industries to delve into innovative approaches to address the everchanging demands of the market, stakeholders, and customer requirements [19]. The traditional approach of defining all requirements upfront and following a linear project progression may not be suitable in such unpredictable market conditions [7, 20]. The APM movement gained momentum in the midst of the ever-increasing dynamism of the market, and it was formalized and characterized by a set of principles and values outlined in the Agile Manifesto, which a group of software developers and thought leaders developed in 2001 [21, 22]. At the core of the manifesto lies the notion that APM has to prioritize the significance of individuals and their interactions, the perpetual delivery of functional software, active customer collaboration, and the ability to adapt to change.

APM methodologies are commonly recognized for their emphasis on flexibility and adaptability [23]. Regardless of the particular methodology that an individual

selects, it is imperative to acknowledge that the pursuit of ongoing enhancement represents yet another pivotal facet of APM [24, 25]. It is customary for agile teams to regularly engage in introspection regarding their processes, actively solicit feedback, and pinpoint opportunities for enhancement. APM entails the cultivation of a culture that prioritizes continuous learning [26]. This approach enables teams to fine-tune their practices, elevate their performance, and ultimately achieve superior outcomes over time. Moreover, one could argue that APM is better suited for technological and complex projects because of its inherent recognition of the potential for project requirements to evolve [27]. This approach embraces change by prioritizing iterative and incremental development, allowing for greater flexibility and adaptability throughout the project life cycle. In the context of a Scrum project, the classical approach of defining all project requirements upfront is replaced by a more dynamic and collaborative process. Here, small and multidisciplinary teams operate in short cycles with the aim of delivering a potentially shippable product increment at the end of each cycle. The use of an iterative approach facilitates teams to effectively integrate feedback, modify priorities, and flexibly adapt their plans as they advance through the project [28].

Since its inception APM has evolved, resulting in the development of numerous methodologies and frameworks, all of which adhere to the fundamental principles and values outlined in the Agile Manifesto. However, they diverge in terms of their prescribed practices and tools, which are tailored to suit the unique requirements of individual project contexts. Thus, one can posit that APM comprises a diverse array of methodologies, each proffering a distinctive approach to providing projects in an iterative and collaborative fashion. As we stated earlier, Scrum stands as the most extensively implemented agile methodology. The State of Agile Report 2022 [29] showed that Scrum continues to be the most widely employed agile framework, with an impressive adoption rate of 87%. Scrum fundamentally places a strong emphasis on the formation of self-organizing teams, the execution of short iterative sprints, and the regular engagement of stakeholders in the collaborative process [30, 31]. The following sections will provide additional information regarding the Scrum framework.

Over time, APM has transcended its origins in software development and has been embraced by a diverse array of industries, including but not limited to manufacturing, health care, and marketing [7, 32, 33]. The principles and practices of the agile methodology have demonstrated their efficacy in tackling the intricacies and dynamism of complex projects [34]. Even companies that are not fully embracing the agile methodology are increasingly seeking to integrate elements of APM into their projects [35]. As an illustration, it is plausible to alter the framework and internal regulations of a conventional project to accentuate collaboration and stakeholder engagement, which is a pivotal facet of APM. Adopting a customer-centric approach empowers teams to provide products and solutions that are in sync with their customer's expectations, thereby resulting in heightened satisfaction and value [36].

#### **3. Agile software and physical product development**

In this particular section, we delve further into the application of Scrum. It is noteworthy that statistics have indicated Scrum to be at the forefront of methodologies in terms of use. The Scrum methodology is extensively employed in the development of software as well as physical products, such as hardware. Although the fundamental

tenets of Scrum remain steadfast across various domains, there exist certain modifications that are particular to the realms of software and hardware development.

#### **3.1 Scrum for software project management**

Scrum provides a structured approach to overseeing the iterative and incremental advancement of software products within software development projects [37]. The approach emphasizes fostering a strong sense of collaboration, promoting transparency, and embracing adaptability as key tenets of its philosophy [38]. The Scrum framework comprises three critical roles—namely, the product owner, the development team, and the Scrum master. These roles are essential in ensuring the successful implementation of the Scrum methodology. The product owner serves as the stakeholders' representative and assumes the role of intermediary between the development team and the client. The product owner bears the responsibility of delineating and assigning priority to the product backlog, a meticulously arranged index of characteristics, improvements, and bug resolutions. The role of the product owner is to ensure that the team is focused on delivering the most valuable items that are in alignment with the overarching goals of the project. For this, it is necessary to have a keen understanding of the project's objectives and a deep appreciation for the stakeholders' needs. By prioritizing the work that needs to be done and providing clear guidance to the team, the product owner plays a critical role in ensuring that the project is successful [39].

The development team comprises a group of cross-functional individuals who deliver the product increment [40]. The composition of this team generally encompasses a diverse range of professionals, such as developers, testers, designers, and other pertinent roles. The team collaboratively addresses the chosen items from the product backlog within sprints. These sprints are brief periods of work, typically spanning two to 4 weeks. The team members engage in a process of self-organization whereby they collaboratively plan their work and make commitments for each sprint.

The role of the Scrum master entails the facilitation of the Scrum process, the removal of impediments, and ensuring the team's adherence to Scrum principles and practices. As a coach, the Scrum master adeptly guides the team toward its goals while simultaneously cultivating a highly productive and collaborative work environment [41]. The role of the Scrum master is to aid in the facilitation of various meetings, including but not limited to the daily stand-up, sprint planning, sprint review, and sprint retrospective.

The Scrum methodology employs a range of artifacts to facilitate efficient project management within the realm of software development. The product backlog acts as the only reliable source of information regarding the scope of the project and directs the work that the team does throughout the duration of the project. The sprint backlog is a crucial artifact in Scrum methodology because it comprises the items that the development team has committed to accomplishing during the sprint. These items are carefully selected from the product backlog, ensuring that they align with the team's capacity and the sprint goal. By maintaining a well-defined sprint backlog, the team can effectively plan and execute its work, ultimately delivering a high-quality product increment at the end of the sprint [42]. The sprint backlog outlines the activities that must be completed to deliver the product increment successfully, and its creation is a team effort. In the context of agile software development, the increment refers to the cumulative sum of all product backlog items that have been successfully completed in a sprint. This term is of utmost importance in the agile methodology because it represents the tangible progress made by the development team toward the ultimate

goal of delivering a fully functional product. The increment denotes a product that holds the potential to be shipped and is capable of delivering significant value to the stakeholders involved [43]. Furthermore, the burndown chart serves as a visual aid that illustrates the amount of work that remains in the sprint backlog as time progresses. This tool is instrumental in enabling the team members to monitor their progress and make necessary adjustments to their efforts. An example of this type of chart can be seen in **Figure 1**.

In summary, we can state that Scrum is capable of providing a structured and collaborative approach to project management. This method enables teams to deliver high-quality software incrementally. Although Scrum is commonly recognized for its efficacy in software development, it can also be adeptly customized to facilitate the development of physical items, as we will elaborate in the following section.

#### **3.2 Agile physical product development**

The Scrum methodology has gained widespread adoption in the realm of software development [44]. However, when it comes to the development of novel physical products, certain modifications must be made to account for the distinctive challenges inherent in such an undertaking. When examining this issue, it is crucial to consider the significance of creating prototypes to facilitate the advancement of the development of tangible products [45]. Incorporating prototyping as a fundamental element of the iterative process is a crucial adaptation that must be made when implementing Scrum in the realm of physical product development. In contrast to software, the development of physical products necessitates the contemplation of a multitude of tangible elements, including but not limited to materials, form, ergonomics, and manufacturability [46]. The process of prototyping enables teams to delve into these various aspects at an early stage, thereby facilitating the identification of design flaws, usability concerns, and potential enhancements [47].

The integration of prototyping into Scrum commences with the product backlog. It is imperative the backlog take into account the inclusion of prototyping activities as

**Figure 1.** *Example of a burndown chart used to measure the progress of work in a sprint.*

#### *Perspective Chapter: Digital Twin Technology as a Tool to Enhance the Performance of Agile… DOI: http://dx.doi.org/10.5772/intechopen.112489*

indispensable constituents of every sprint. It is imperative to allocate sufficient time and resources to the prototyping phase within the development cycle to guarantee its efficacy. The product owner, in close collaboration with the team, meticulously defines user stories and tasks that are pertinent to the prototyping activities. Throughout every sprint, the development team diligently engages in the process of constructing prototypes that are in accordance with the prioritized features and requirements. As was already seen, the team comprises individuals who possess a wealth of knowledge and experience in various fields, such as industrial design, engineering, manufacturing, and other pertinent disciplines. Together, the team works in unison to produce prototypes that effectively encapsulate the proposed product's fundamental qualities.

Thus, it is apparent that the integration of prototyping with Scrum methodology can yield numerous advantages in the realm of physical product development. To begin with, it enables teams to authenticate design concepts and evaluate functionality [48]. Through the development of preliminary models, teams have the opportunity to obtain valuable input from stakeholders, users, and prospective clients. This feedback empowers them to make well-informed judgments and refine the design and functionality of the product through iterative processes. The use of an iterative feedback loop serves as a valuable tool for teams to enhance the quality of their prototypes and ensure that the product is in sync with the requirements of the end users and the market. In addition, the process of prototyping serves as a valuable tool for assessing the potential manufacturability and production feasibility of a given physical product [49]. The development of prototypes that bear a strong resemblance to the ultimate product enables teams to evaluate a range of factors, including material compatibility, assembly processes, and cost considerations [50]. The prompt detection of manufacturing limitations or obstacles confers upon teams the ability to effectuate requisite design adjustments, thereby guaranteeing a seamless progression from prototype to production.

Therefore, prototyping combined with the Scrum framework presents a multitude of opportunities for the exhibition of prototypes and the acquisition of feedback. The sprint review is an invaluable opportunity to showcase the latest prototype to stakeholders, affording them the chance to experience the product's form and functionality directly. The feedback that is received plays a significant role in shaping the product's subsequent iterations. It serves as a driving force for improvements and helps to align the product with the desired outcomes. Moreover, the retrospective meeting within the Scrum framework offers a valuable opportunity for the team to engage in introspection regarding its prototyping practices. This space allows for the identification of areas that require improvement as well as the sharing of insights that have been gathered throughout the project. The process of iterative learning is instrumental in enabling teams to fine-tune their prototyping methodology, thereby enhancing its efficiency, efficacy, and alignment with project objectives [51].

In essence, the use of Scrum methodology for the purpose of developing novel physical products yields significant advantages, particularly when emphasis is placed on the prototyping phase. The integration of prototyping within the Scrum framework presents teams with the opportunity to validate design concepts, collect valuable feedback, and refine the product through an iterative process. Incorporating prototyping activities into the product backlog, allocating ample time and resources for prototyping iterations within each sprint, and using the sprint review and retrospective meetings to validate products and processes can enable teams to leverage all the potential of prototyping effectively. The result can be the development of superior physical products that respond to user requirements, align with market

trends, and foster innovation. The employment of this tool enables teams to generate concrete depictions of their concepts and blueprints, thereby furnishing a medium for scrutinizing, assessing, and enhancing the product during the project evolution. As we delve deeper into the subject matter, it becomes apparent that the integration of DT technology into the Scrum framework can yield more significant advantages for teams, thereby increasing even more their likelihood of success.

#### **3.3 Challenges with complex physical product development**

As evidenced in the preceding section, prototypes function as concrete manifestations of the product, affording teams the opportunity to authenticate and enhance design concepts, assess functional components, and amass invaluable user input. The process of prototyping assumes a pivotal role in the development of physical products within the Scrum methodology. The use of this tool allows agile teams to expeditiously recognize and tackle potential design flaws or usability issues at the outset of the development process, thereby reducing the need for future expensive revisions [52]. However, the integration of products that distinct Scrum teams develop can pose several challenges, despite the employment of diverse prototypes. These challenges primarily pertain to interfaces and information communication. As each team concentrates on the development of specific components or modules, it is imperative to pay meticulous attention to interface design and effective communication practices to ensure seamless integration [53]. In this section, we will delve into several pivotal obstacles that pertain to interfaces and information communication.

Medium to complex projects often face multiple risks and potential issues arising from the various interface compatibilities [54, 55]. Interfaces serve as the crucial junctions that link distinct components or modules that separate teams have developed. It is of utmost importance to ensure compatibility across interfaces to facilitate a seamless integration process toward the final and comprehensive product that meets the required standards of quality. In the realm of complex projects, a multitude of challenges may arise when teams interpret interface requirements in varying ways or when modifications to one component have a consequential impact on the functionality of other components that depend on it. Effective communication and seamless collaboration among teams are crucial for establishing and sustaining compatible interfaces throughout the development process of complex projects [56].

In complex projects, interface specifications that are ambiguous or incomplete can give rise to a multitude of issues. Inconsistencies and delays may arise when multiple teams hold divergent interpretations of interface requirements. To ensure the success of complex projects, normally a significant amount of time should be dedicated to the initial phase of defining thorough and unequivocal interface specifications [57]. This approach serves to mitigate the likelihood of any potential issues arising throughout the project's lifespan. In the context of APM, it is worth noting that the aforementioned issue can be somewhat alleviated. This is because of the fact that frequent communication and clarification between teams can facilitate a collective comprehension of interface requirements, thereby circumventing any potential misalignment [58]. In complex projects, it is imperative for teams to effectively communicate updates, progress, and potential issues pertaining to their respective components. The occurrence of delays or miscommunication in the dissemination of information can impede the integration process, ultimately resulting in misunderstandings or conflicts [59, 60]. The establishment of effective communication channels, such as scheduled meetings

*Perspective Chapter: Digital Twin Technology as a Tool to Enhance the Performance of Agile… DOI: http://dx.doi.org/10.5772/intechopen.112489*

or digital collaboration platforms, can greatly facilitate the timely and transparent exchange of information.

Nevertheless, in the case of a complex project, different Scrum teams may run different sprint cycles or have divergent development timelines. The integration of their products can pose certain challenges. The occurrence of misalignment in timelines can potentially result in undesirable delays or compel teams to operate on incomplete components, thereby adversely affecting the overall integration process [61]. One potential solution to address these challenges and facilitate a seamless integration process is to coordinate and synchronize sprint cycles or to establish clear dependencies and sequencing of work between teams. By doing so, teams can work together more effectively and efficiently, ultimately leading to a more successful outcome. In addition, it is important to note that as the development process advances, modifications made to a particular component may potentially trigger a series of consequential impacts on other components that rely on it. The task of coordinating and managing changes and dependencies can prove to be quite challenging, particularly when multiple Scrum teams are involved [62]. Well-defined change management procedures, efficient communication channels, and a cooperative strategy for handling interdependencies can significantly reduce risks and guarantee a smooth integration of modifications into the overall product [63, 64].

In summary, it is imperative to acknowledge that the seamless integration of products from diverse Scrum teams necessitates efficient knowledge dissemination and collaboration. Each team possesses a wealth of valuable insights and expertise that are directly related to their respective components. Nonetheless, the inadequate dissemination and use of this valuable knowledge has the potential to impede the straightforward assimilation process. Facilitating cross-team collaboration, promoting knowledge transfer sessions, and fostering a culture of open communication can effectively encourage the exchange of ideas, insights, and best practices. This way of working, in turn, can significantly enhance the integration of different products. As we will see in the next section, it is imperative to acknowledge that in the context of physical product development, the DT can take the form of an indispensable tool for facilitating seamless and effective knowledge transfer among teams.

#### **4. Agile project management and digital twin: a powerful combination for complex projects**

As evidenced in the preceding section, the integration of products that various Scrum teams have developed can present certain challenges, particularly regarding interfaces and the communication of information. To achieve successful integration, it is essential to address interface compatibility, ensure clear and comprehensive interface specifications, facilitate timely information exchange, synchronize development timelines, promote knowledge sharing and collaboration, manage changes and dependencies, and implement continuous integration and testing practices of the product increments [65]. These factors play a critical role in ensuring that the integration process runs smoothly and efficiently. Therefore, it is imperative to prioritize these aspects and allocate adequate resources toward their implementation.

The solution proposed by this chapter is the integration of DT into an APM framework, such as Scrum. This integration is illustrated in **Figure 2**. The benefits of employing a DT in the complex levels of APM for the development of physical products are manifold. We will expound upon these advantages in the ensuing section.

**Figure 2.** *Scrum framework using DT for complex physical product development.*

By using this technology throughout the project, one can take a proactive approach toward addressing the challenges that might arise in complex projects despite the proper use of an agile approach.

#### **4.1 Digital twin: a solution for managing complexity in agile project management of physical products**

In the realm of complex physical product development projects, DT technology assumes an essential position, particularly when multiple teams are engaged in the development of diverse subsystems [66]. In complex projects, teams are often frequently geographically dispersed [67]. Consequently, the collaboration process, as well as the combination of the evolution of their subproducts and the results of testing from prototyping, can become even more challenging. However, it is worth noting that the integration process can be significantly streamlined through the use of DT technology. By leveraging the virtual representation of the physical product or subsystem, teams can effectively collaborate and exchange information regarding the project's evolution. This approach enables seamless teamwork and promotes efficient communication among team members [11].

The use of DT technology in APM enables each team to develop its specific subproduct independently, with a concentrated emphasis on its designated areas of expertise. The premise at hand is that the DT functions as a shared point of reference, facilitating cooperation and integration among the teams in question [68]. DT technology offers a collaborative platform that enables teams to visualize, analyze, and interact effectively with their respective subproducts. The use of DT technology fosters a sense of alignment and facilitates the integration process, which is a significant source of risk in complex projects. This way of working is shown schematically in **Figure 3**. The implementation of DT technology will enable teams to integrate their subproducts seamlessly in a virtual environment, facilitating the analysis of multiple interfaces and the refinement of their product backlogs.

By means of the integration that DT technology facilitates, agile teams are able to gain a comprehensive view of the entire scenario, even when they are geographically dispersed across different regions of the globe. Every team has the opportunity to make a valuable contribution to the DT by providing its respective subproduct, thereby ensuring that all components are seamlessly integrated. Virtual integration eliminates the necessity for physical conveyance of prototypes, diminishes temporal delays, and facilitates instantaneous collaboration [11]. The integration of

*Perspective Chapter: Digital Twin Technology as a Tool to Enhance the Performance of Agile… DOI: http://dx.doi.org/10.5772/intechopen.112489*

#### **Figure 3.**

*Several agile teams exchanging information and refining their respective product via DT.*

collaboration tools and communication channels within the DT platform serves to strengthen teamwork among geographically dispersed teams. Team members are able to engage in effective communication, exchange valuable feedback, and arrive at mutually beneficial decisions through the employment of the virtual platform.

DT technology facilitates the remote monitoring and control of physical entities, even in geographically dispersed locations, particularly in complex projects. Project teams have the ability to conduct remote assessments of performance, detect any anomalies that may arise, and take the appropriate actions as needed. The implementation of remote monitoring and control systems has proven to be a highly effective means of enhancing operational efficiency, minimizing the necessity for physical presence, and facilitating prompt responses to any arising issues [69]. Furthermore, DT technology offers advantages that transcend the development phase because it continues to provide value throughout the entire product lifecycle.

In essence, the use of DT technology within the context of complex APM of physical products yields significant benefits to project coordination. The project's success is achieved through the facilitation of iterative design and testing processes as well as the rapid synchronization of teams involved in module prototyping and simulations. Through the development of virtual prototypes of tangible entities and the subsequent exploration of diverse design alternatives in a virtual environment, the necessity for physical prototypes is significantly diminished. The development team has the opportunity to use integrated real-time data from a multitude of sources, including but not limited to sensors, IoT devices, and monitoring systems [70]. The capability to share data guarantees that additional stakeholders, including clients, are granted access to the latest and most accurate information. In complex projects, the exchange of real-time data diminishes the possibility of operating with obsolete or contradictory information, thereby augmenting project efficacy and agility. Henceforth, DT not only serves as a resolution to the numerous specific obstacles encountered during

the development of physical products, but it also has the potential to further improve APM across various knowledge domains of project management.

To summarize, the implementation of a DT in an agile project that involves numerous geographically dispersed teams collaborating on a complex new product yields several benefits. The provision of a shared reference point for all stakeholders facilitates collaboration and knowledge sharing. The DT's capacity for real-time functionality facilitates expeditious decision-making and adaptability. The use of virtual testing and experimentation has proven to be a highly effective means of reducing costs and expediting the development process. Furthermore, the implementation of DT technology elevates the general quality and robustness of the product, resulting in heightened levels of customer satisfaction.

#### **4.2 Enhancing agile project performance with digital twin technology**

As we have demonstrated, APM offers a comprehensive framework for effectively tackling the intricacies of complex projects. Moreover, it is noteworthy that the DT constitutes a virtual platform that enables teams to combine their efforts, gain a comprehensive visualization of the entire system, and conduct integration testing in a virtual environment. The integration of DT technology with complex physical product projects can yield numerous benefits for project management. For instance, by using virtual representations, stakeholders can be more effectively engaged, project scope can be managed with greater efficiency, product quality can be ensured, costs can be optimized, delays can be minimized, and technical risks can be mitigated.

The concept of DT presents a remarkable opportunity for collaborative efforts in project management. This innovative solution proves particularly advantageous in the development of complex physical products, especially when dealing with teams that are geographically dispersed. By facilitating the integration of subproducts, DT technology enables seamless collaboration among team members, thereby enhancing the overall efficiency of the project. This particular feature enables the product owner, in particular, to examine and deliberate upon the entity from various angles, thereby enhancing lucidity and minimizing ambiguity in conversations with customers.

DT technology offers a virtual replica of complex products, allowing stakeholders to seamlessly engage with and visualize the product in a realistic and intuitive manner [71]. This visualization serves as a valuable tool for stakeholders because it enables them to gain a comprehensive understanding of the product's behavior, capabilities, and potential challenges. This, in turn, facilitates informed decision-making, which is crucial for the success of the project. Stakeholders are encouraged to engage actively in the development process by providing constructive feedback, offering insightful suggestions for improvement, and ensuring that their unique requirements and expectations are effectively addressed. Such active participation is highly valued by most stakeholders and can significantly enhance the overall quality of the development process. The use of DT technology promotes cooperation and cultivates a shared sense of responsibility among stakeholders, ultimately leading to enhanced project results and heightened stakeholder satisfaction.

The optimization of product design is a crucial objective in the development of complex products. In this regard, DT presents a potent platform that can be leveraged to attain this goal. Using the virtual environment, teams have the opportunity to examine various design iterations thoroughly, evaluate their efficacy, and ultimately make informed design decisions based on data-driven insights [72]. The capacity to iterate expeditiously within the digital realm enables the attainment of more efficient *Perspective Chapter: Digital Twin Technology as a Tool to Enhance the Performance of Agile… DOI: http://dx.doi.org/10.5772/intechopen.112489*

and effective design optimization, culminating in products that surpass or meet customers' expectations.

The implementation of DT technology offers a valuable opportunity for teams to examine various design alternatives thoroughly. This process allows for the identification of the optimal design configuration that effectively balances performance, cost, and other critical factors. The use of DT technology in the optimization of product design serves to augment the overall competitiveness and marketability of the end product [73]. Furthermore, the use of DT technology empowers teams to validate the functionality of a product, optimize its performance, and ensure that it meets the desired quality standards.

In the same token, in the realm of product design, quality assurance is an indispensable element of complex product development projects. In this regard, DT technology plays an essential part in guaranteeing the quality of the product. DT technology facilitates a virtual environment that allows for comprehensive testing, simulations, and performance evaluations [11]. This innovative approach empowers teams to monitor the behavior and performance of the product closely, thereby enhancing the overall quality of the result of the project. The use of DT in APM facilitates the prompt identification and rectification of any design deficiencies, inadequacies, or operational hindrances.

It is also important to note that in the realm of project management, it is frequently the case that the overall success of a given endeavor is contingent upon the expeditiousness with which it is brought to fruition [74]. The ramifications of project timeline delays can be quite substantial, particularly in the realm of complex product development. However, DT technology can be instrumental in mitigating such delays by enabling teams to swiftly execute iterations, simulations, and scenario planning [11, 75]. By simulating various scenarios and evaluating their effects on project timelines, teams can effectively identify and address potential delays in the development process.

In addition, it is worth noting that APM's collaborative and transparent approach, when coupled with the remarkable abilities of DT technology, promotes seamless communication and alignment among all team members and stakeholders, which helps mitigate any potential delays that may arise as a result of miscommunication or misalignment. In the case of complex product development, effective cost control is an essential component that transcends only timely completion. In this regard, DT technology presents a host of significant benefits. The use of DT's virtual environment empowers teams to effectively optimize resource allocation and efficiently identify opportunities for cost-saving measures. Through the process of simulating diverse scenarios, teams are able to evaluate the effects of multiple factors on costs, thereby enabling them to make informed decisions that optimize resource use. The use of DT technology also enables effective collaboration and communication among teams that are geographically separated, thereby diminishing the necessity for physical presence and the accompanying travel expenses [11, 73]. Another important benefit of the use of DT in APM is that the capacity to identify and rectify design deficiencies or performance inadequacies in the initial stages of the development process serves to mitigate the expenses associated with extensive rework or redesign.

It is imperative to remember that complex product development naturally entails technical risks [76, 77]. However, the use of DT technology also effectively alleviates these risks. The DT platform offers a virtual environment that enables teams to create models and simulate complex technical systems. This allows for the identification of potential issues, evaluation of various design alternatives, and informed

decision-making to mitigate risks. The implementation of a proactive risk management approach can effectively decrease the probability of encountering technical setbacks, rework, or failures, thereby augmenting the project's overall triumph. When managing complex projects, DT with APM entails more than just basic risk management. In fact, it incorporates learning and knowledge management into the mix. As teams engage with DTs, they acquire valuable insights and knowledge regarding the product and its behavior. The insights are subsequently shared among the organization's members via DT. This process of knowledge transfer not only facilitates the dissemination of valuable information but also nurtures a culture of perpetual learning within the organization [78, 79].

The knowledge and insights gained from past projects can be effectively used in upcoming projects, resulting in enhanced levels of efficiency and efficacy. The use of DT as a knowledge repository enables teams to conveniently access and capitalize on prior experiences, thereby mitigating the possibility of reiterating errors and fostering the adoption of optimal methodologies. The implementation of DT technology enables organizations to bolster their capabilities and expertise through the facilitation of learning and knowledge management, which leads to improved project outcomes and heightened competitiveness in the market.

In summary, the mutually beneficial connection between APM methodologies applied to complex product development and the use of DT technology presents significant advantages for businesses. APM is a highly adaptable and iterative approach that enables swift responsiveness to evolving customer requirements and market dynamics. DT technology offers a virtual depiction of the tangible product, facilitating continuous monitoring, experimentation, and evaluation during the entire duration of the product's existence. The amalgamation of these two fundamental concepts engenders a robust framework that enables the optimization of product development while concurrently augmenting customer satisfaction.
