Monitoring and controlling a project is a process to track, review and revise the project activities which can be done by project manager to ensure the project is on right track and creates the deliverables in accordance with the project activities. I think projects that adaptive and extreme are least stable than traditional projects because traditional projects are clear and well understood; therefore, it is more stable. Sometime well planned projects require a change from time to time. However change costs money, time and risk associate with that change. Regularly monitoring the progress helps to ensure that there is no unpleasant surprise as the project unfold. I believe most essential phase of the design control is variance report. Variance report generated by the earned value management system (quality control system). It compares what has actually happened on a project against what was expected to happen on the project. Variance report indicates actual value and a percentage of the difference to achieve better performance on a project activities such as cost and duration. Project variance reports are expressed as what was supposed to have happened since the last reporting cycle called “current period” and what was supposed to have been done on the project since it started known as “Cumulative variance.”
