Trend analysis is not necessarily part of each tracking cycle, but it is useful to examine the trends in the status data at least during project reviews. Use trend analysis to detect budget, schedule, and other problems as early in the project as possible. If trend analysis reveals a need for negotiating project changes, such as the project end date, the budget, staffing, or project deliverables, deal with this as soon as possible. The earlier you propose needed changes, the more likely you will be to get support and agreement. Waiting too long to confront trends often leads to canceling projects.
