XP Principle 1: Allow Rapid Feedback

The principle of rapid feedback enhances the value of feedback by pumping the received feedback back into the XP environment as quickly as possible. The business receives rapid feedback in days and weeks, and developers receive rapid feedback in seconds and minutes. This is all accomplished by selecting XP practices that provide this type of feedback.

For example, acceptance tests are written during an iteration starting with the first iteration. In a waterfall approach, these tests would not be available until the end of the project. Acceptance tests provide the business with rapid feedback in days and weeks, instead of months or years.

Another example of rapid feedback is unit tests, which we will discuss later in this chapter when we cover the seventh XP practice of testing. This provides the developers with rapid feedback in seconds and minutes, instead of a waterfall approach where this type of feedback may not be available for weeks or months.
