Disciplines

Disciplines are "containers" used to organize activities of the process. There are nine main disciplines in the Rational Unified Process, and they represent a partitioning of all roles and activities into logical groupings by areas of concern or specialty (see Figure 3-5). The nine core disciplines are divided into six technical disciplines and three supporting disciplines.

Figure 3-5. Nine core disciplines

The technical disciplines are as follows :

• Business modeling discipline

• Requirements discipline

• Analysis and design discipline

• Implementation discipline

• Test discipline

• Deployment discipline

The supporting disciplines are as follows:

• Project management discipline

• Configuration and change management discipline

• Environment discipline

Although the names of the six technical disciplines may evoke the sequential phases in a traditional waterfall process, you will see in Chapter 4 that the phases of an iterative process are quite different and that these disciplines and the activities and workflows they contain are revisited again and again throughout the lifecycle. The nine main disciplines are discussed in detail in Chapters 7 through 15.
