上游充通大粤 Project Control Process SHANGHAI JLAO TONG UNIVERSITY The key to effective project control is measuring actual progress and comparing it to planned progress on a timely and regular basis and taking corrective action immediately to get the project back on track. To keep track of which activities have been started and/or completed,when they were started and/or completed,and how much money has been spent or committed

上游充通大学 Effects of Actual Schedule Performance SHANGHAI JIAO TONG UNIVERSITY Actual progress-whether faster or slower than planned- will have an effect on the schedule of the remaining, uncompleted activities of the project. Actual finish times(AFs)of completed activities will determine the earliest start and earliest finish times for the remaining activities in the network diagram,as will as the total slack

Effects of Actual Schedule Performance Actual progress — whether faster or slower than planned — will have an effect on the schedule of the remaining, uncompleted activities of the project. Actual finish times (AFs) of completed activities will determine the earliest start and earliest finish times for the remaining activities in the network diagram, as will as the total slack

When the customer request a change,impact on the project should be estimated
