**4.3 Outcome**

When considering all the various themes discussed in this chapter, it appears that tacit knowledge is a knowledge that is created unconsciously, at any moment, within our brains. This knowledge plays a key role in the interactions between people and digital information systems in the exchange of information necessary for ongoing decisionmaking related to their activities. For example, we believe that an individual's behavior is triggered by information that, in a given context and situation, is interpreted through its interpretative framework and becomes tacit knowledge that makes it act in the form of interactions with other individuals and the digital information system.

Moreover, our constructivist and sociotechnical approach and the distinction we make between data, information, and knowledge led us to develop a model called "Organizational Information and Knowledge System (OIKS)" [2, 18]. This model is a local subset of the organization's sociotechnical system (individuals interacting between themselves, with machines, and with the system itself). In this model, individuals and their interactions with the digital information system are represented. It has become a reference in our thought patterns.

In the following Section 5, considering all the various themes discussed in this chapter, we study an example of *ad hoc* infrastructures that can be used in the age of new normal described Section 2.
