Part 2. Project Initiation

When developing use cases it is extremely important that the use case model’s place in the overall system development effort be well understood. When embarking on the system development effort, it can be tempting to jump in and start use case modeling right away. Although use cases were created to be applied in the early stages of system development, and although they are a very flexible technique, they are not the only technique that can be used to understand and model the system.

One of the greatest areas of both leverage and risk when developing a software system is in the initial scope of effort. This is where the overall concept of how the system will operate and support the business environment evolves. The ...
