Side Effects
                    • Weekly stakeholder demos retained
                    • Weekly retrospectives retained
                    • Team and Product Owner
                          conversations happened naturally &
                          frequently

Natural Evolution
                • Instead of holding weekly formal
                          retrospectives, retrospect and fix
                          problems as they happen.
