Iterations Iterations are generally two to three weeks long with releases being every one to three months. Management and Staff Relationships Trust between staff and the manager is essential. The manager provides direction for change incrementally. The manager does not assign work, but sets priorities and shows what should be done. The manager may not assign the work to individuals if the trust relationship between the group and manager is healthy enough.
Communication is essential.
The manager must get the team to make good decisions. The manager measures project velocity while the team reports progress. Project velocity is the ratio between estimated time and real calender time. Too many metrics become meaningless. The business and development sides must be understanding and work closely together.
