Iterative Development

To minimize the risk of project failure, your development process can be iterative and incremental. Using an iterative technique means feedback from a phase can cause reiteration of a previous phases. For example, a significant performance issue might require a UI redesign that causes a reiteration of subsequent phases.

Using an incremental technique means that the best way to mitigate the risks of using new technology, such as Siebel Task UI, is to begin with a smaller scope, deliver it to customers, and then use customer feedback to incrementally create functionality. For brevity, this chapter does not fully describe iterations and incremental releases. However, most implementations include iterations and incremental releases, and it is recommended that you plan for them.
