You mentioned the 4+1 model, how do you personally use it?

Model 4+1 architectural views are used for structuring and documenting the system architecture from different perspectives:

• Logical View — describes the main components and their interactions, helping to understand the system structure from a developer's point of view.

• Process View — models the dynamic behavior, data flows, and control, which is important for assessing performance and parallelism.

• Physical View — reflects the deployment of components on hardware resources, aiding in infrastructure planning.

• Development View — shows the organization of code and modules, facilitating maintenance and scaling.

• Use Case View — describes key usage scenarios, linking all views and ensuring understanding of requirements.

In practice, I create diagrams and documentation for each of these views, which helps the team better understand the architecture, identify bottlenecks, and coordinate changes.
