Software Architect's Handbook

Step 4 – Evaluate scenarios

In this SAAM step, the scenarios are evaluated. For each of the direct scenarios, the software architect demonstrates how the architecture can execute it. For any indirect scenarios, the team should identify what has to be changed (for example, modification/addition/deletion of components) in order to execute each one. The team should estimate the level of effort necessary to change the system so that it can execute indirect scenarios.
