Software development companies started to adopt the principles of Extreme Programming and Agile Development to help reduce risk in a world where change is inevitable. To help adapt to this inevitable change, agile principles call upon feedback and a lot of it. Many people understand the importance of customer feedback (advice during requirements meetings, user acceptance testing, etc…) and unit tests, which gives developers instant feedback several times a day. An equally important source of feedback comes from the testing team who can provide quick, quality feedback.
