After making a change, a team should ask: what did we expect to happen? what did happen? were there unintended consequences? what was the best thing about this change? The worst? what might we do next? Too often, people avoid reflecting on failure. Remember that teams often learn very important lessons from failed tests of change. Briefly describe the changes made with your improvement project that failed. Use these questions as a basis for discussion. If your improvement project does not apply, you may choose a change you have made in the past.
