8.6 Conclusion

The detailed design process presented in this chapter is driven by a number of the methodological principles discussed in Chapter 3. Approaches have been described for soliciting end-user input to support design decisions, considering context during design, and focusing the process on conversational design. We have also introduced a set of design principles that should guide design decisions.

Skill at applying the process will take experience in designing real applications. To illustrate the process in operation and to show some of the issues, decisions, and trade-offs that arise during detailed design, in Chapter 14 we continue the sample application for Lexington Brokerage, showing the detailed design phase. However, first we discuss the design principles in detail and show how they are applied to detailed design decisions (Chapters 9 13).
