The correct answer is D. All the above.
A CPM family includes CPA (Critical Path Analysis), CPP (Critical Path Plotted), and MCE (Minimum Cost Expenditure).
CPA is a project management technique used to analyze and plan the scheduling of a project. It is a network diagramming technique that shows the sequence of tasks required to complete a project and the dependencies between those tasks.
CPP is a graphical representation of the critical path in a CPM network. The critical path is the longest path through the network, and it determines the shortest possible time to complete the project.
MCE is a technique used to minimize the cost of completing a project. It involves identifying the critical path and then scheduling the tasks on that path so that they are completed at the lowest possible cost.
CPM is a valuable tool for project managers because it can help them to:
- Identify the critical path and the tasks that must be completed on time to avoid delays
- Estimate the time and cost required to complete the project
- Identify and manage risks
- Monitor progress and make adjustments as needed
CPM is a complex technique, but it can be very helpful for managing complex projects.
