Definition of 'Critical Path Analysis' A project-management technique that lays out all the activities needed to complete a task, the time it will take to complete each activity and the relationships between the activities. Also called the "critical path method", critical path analysis can help predict whether a project can be completed on time and can be used to reorganize the project both before starting it, and as it progresses, to keep the project's completion on track and ensure that deliverables

PROJECT CONTROL WITH PERT/CPM CPM (Critical Path Method) determines the longest path and the critical activities along this path in a project network; the project completion time can't be shorter than the duration of this longest path unless such techniques as time crashing are used. PERT (Program Evaluation and Review Technique) incorporates probabilistic elements into the computation of activity durations and hence the project completion time; PERT uses optimistic (o), most probable (m)

D Follow this sequence: 1. Construct the Network diagram. 2. Check the network diagram. 3. Add durations to the activities. 4. Identify all paths through the network. 5. Identify the critical path (CP) and scheduled duration. 6. Calculate slack times (float) for each activity. 1. Construct the Network diagram. Using the AIB method: Draw a box on the left labeled "Start" Add boxes to the right of this box for activities with no predecessors, in the example A, and B. Connect these

Production management Critical Path Method (CPM): 1) Critical Event: An event in the project which cannot be delayed by any amount of time beyond its earliest occurrence time without affecting total project completion time. 2) Critical Activity: An activity whose start or completion cannot be delayed by any amount of time without affecting total project completion time. Float of critical activity is zero. Necessary and sufficient conditions for identifying critical activities:
