Design plan

If you sit down to design and develop more that a simple system, such as a whole network stuffed with services such as Systems Management Server, Exchange 20030, and Windows Server 2003, a design roadmap helps. Such a roadmap typically exists in the form of a governing document known simply as a design plan.

Design plans normally also list the various approaches that you intend to take in your architecture and design methodology. Following is a short list of items that we put into our own design plans:

♦ Choice of architectural framework or approach, such as the Zachman Framework

♦ Design methodology, such as the System Development Life Cycle model, Rational Unified Process (RUP), and so on

♦ Risk-management approach

♦ Documentation lists and various documentation styles
