However, as you progress through the patterns and practices, you'll build on what you have so far and uncover more of the framework components and how best to implement them to meet the quality characteristics. What you have so far would not be "client-ready," but it is good enough for further design and planning meetings. You are looking to get a complete view of the application and its functionality so that you can really start to apply the patterns and practices and concentrate on the key areas. The diagrams and flows help to walk through the conceptual solution. The requirements specified in Chapter 13 identified a number of batch jobs, and this chapter provides an overall view of the functionality and requirements.
