Project management involves the planning, monitoring, and control of people, process, and events that occur during software development. Everyone manages, but the scope of each person's management activities varies according his or her role in the project.

High frustration caused by personal, business, or technological factors that cause friction among team members. “Fragmented or poorly coordinated procedures” or a poorly defined or improperly chosen process model that becomes a roadblock to accomplishment. Unclear definition of roles resulting in a lack of accountability and resultant finger-pointing. “Continuous and repeated exposure to failure” that leads to a loss of confidence and a lowering of morale.

This is accomplished by working hard (very hard) to understand the problem that is to be solved and then setting realistic objectives and expectations. Maintain momentum. The project manager must provide incentives to keep turnover of personnel to an absolute minimum, the team should emphasize quality in every task it performs, and senior management should do everything possible to stay out of the team’s way.
