Be aware of the classic mistakes. Create lists of "worst practices" to avoid on future projects. Start with the list in this chapter. Add to the list by conducting project postmortems to learn from your team's mistakes. Encourage other projects within your organization to conduct postmortems so that you can learn from their mistakes. Exchange war stories with your colleagues in other organizations, and learn from their experiences. Display your list of mistake s prominently so that people will see it and learn not to make the same mistakes yet another time.
