and that flow is modeled in an easy-to-understand way. It provides structure to the business flows that arise, but the real value is the conversations involved. You can build a software system from the models or simply use the knowledge gained from the discussions to better understand and refine business processes.

explain applications and their systems from the general to the particular. This means that we can explain a system in 5 minutes, in 1 hour or in 5 hours. The 4 phases of the model are: system context, container diagram, component diagram, and code. https://c4model.com/ https://structurizr.com/ Molecular structure of natural rubber Visualize your Architecture (C4 diagrams)
• Prevent the architecture definition from drifting over time. • Set architecture guidelines in the team • Automated tests with technical agreements at team level Goals
