CPM is A. Synthesising in concepts B. Is built of activities oriented programme C. Is based on time estimate D. All the above

The correct answer is D. All the above.

CPM stands for Critical Path Method. It is a network analysis technique used in project management to plan and schedule a project. It is based on the concept of a critical path, which is the longest sequence of activities in a project that determines the overall project duration.

CPM is built on the following principles:

• Activities are represented by nodes in a network diagram.
• The precedence relationships between activities are represented by arrows in the network diagram.
• The duration of each activity is estimated.
• The critical path is determined by finding the longest path through the network diagram.
• The earliest and latest start and finish times for each activity are determined.
• Float is the amount of time that an activity can be delayed without delaying the project.
• The critical path activities have zero float.
• Non-critical path activities have positive float.
• CPM can be used to identify and schedule critical path activities, to calculate float for non-critical path activities, and to develop a project schedule.

CPM is a powerful tool for project management. It can help to ensure that projects are completed on time and within budget. It can also help to identify and manage risks.

Here is a brief explanation of each option:

• Option A: Synthesising in concepts. CPM is a method for planning and scheduling projects. It is based on the concept of a critical path, which is the longest sequence of activities in a project that determines the overall project duration.
• Option B: Is built of activities oriented programme. CPM is a network analysis technique. It is built on the concept of a network diagram, which is a graphical representation of the activities and precedence relationships in a project.
• Option C: Is based on time estimate. CPM is based on the estimation of the duration of each activity in a project. The critical path is determined by finding the longest path through the network diagram, taking into account the estimated durations of the activities.

I hope this helps!
