Control Schedule

Posted on June 4, 2009 by


The Control Schedule process is one of the 42 project management processes described in the fourth edition PMBOK®. It’s one of the six Time knowledge area processes, and one of the ten Monitoring and Controlling processes. The primary purpose of this process is to update progress and manage any changes to the project schedule. The Project Management Plan contains the Schedule Baseline and the Schedule Management Plan which outlines how changes to the schedule are to be made. The most recent Project Schedule is compared to Work Performance Information in order to gauge how well the project is on-schedule. Comparing actual progress to planned progress is called Variance Analysis, and this leads to the output of Work Performance Measurements. With the mathematical calculations involved, Project Management Software and Scheduling Tools are useful for ease of making schedule changes. If the work needs to be performed over a shorter duration of time, Schedule Compression techniques such as crashing and fast-tracking may be needed. Adjusting Leads and Lags and Resource Leveling are other tools to adjust the schedule. When changes are needed, there will be Change Requests which go through the Perform Integrated Change Control process. Updates may also be needed to Organizational Process Assets, the Project Management Plan, and Project Documents.
