Principle 12 - Reflect. Improve. Repeat.

“At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.”

One of the main concepts of agile methodologies is the concept of iteration and continuous improvement. Iteration allows the teams to correct or fix mistakes before it is too late, it also helps teams learn from their mistakes and continually improve the process and their performance. This, in turn, ensures that the end product is of very good quality and closely reflects the customer’s requirements.
