**2. Concept of PLM**

PLM is above all a business strategy. It can be defined as an approach collaborative management of product information throughout its life cycle [6].

We also adopt the vision of Francis Bernard, co-founder of Dassault Systemes and creator of CATIA computer-aided design software that considers PLM is a business solution that allows simulating virtually the reality of the digital product: the complete life of the product and its environment, integrating all partners in a collaborative mode [7].

A PLM system automates and simplifies the process of developing new products. This system manages critical product information, product life cycle, and value chain. PLM systems maximize development efforts of new products and significantly increase the company's performance [8].

**4. Methodology of designing the product and its supply chain**

We will exploit the PLM approach in our methodology by:

• Simultaneous design of the product and its supply chain:

to manage the growing pressure of supply chains [11].

• Capitalization and archiving of all data.

PLM connects employees to enable them to collaborate and centralize the process of the development of new products. It simplifies the steps by which one must pass for design and manufacture and support the products offered by the company. A PLM system organizes the development from the point of view of customer constraints, production costs, sales history, or other information about the existing products in the business [9].
