Node Representation

  • Activity label is the name of the activity represented by that node.
  • Earliest Start is the date or time at which the activity can be started at the earliest.
  • Earliest Finish is the date or time at which the activity can be completed at the earliest.
  • Latest Start is the date or time at which the activity can be started at the latest.
  • The latest Finish is the date or time at which the activity can be finished at the latest.
  • Float is equal to the difference between the earliest start and latest start or earliest finish and latest finish.

Critical Path Method for Project management

Critical Path Method (CPM) is a method used in project planning, generally for project scheduling for the on-time completion of the project. It helps in the determination of the earliest time by which the whole project can be completed. There are two main concepts in this method namely critical task and critical path.

What is a Critical task in project management?

It is the task/activity that can’t be delayed otherwise the completion of the entire project will be delayed. It must be completed on time before starting the other dependent tasks....

What is the Critical path in project management?

It is a sequence of critical tasks/activities and is the largest path in the project network. It gives us the minimum time which is required to complete the entire project. The activities in the critical path are known as critical activities and if these activities are delayed then the completion of the entire project is also delayed....

Benefits of using the critical path method in project management:

Show the project schedule visually. Highlight important tasks with CPM. Use CPM to find and handle risks. CPM helps the project team communicate better....

How to find the critical path in a project:

Step 1: Identify all tasks required to complete the project Step 2: Determine the sequence of tasks Step 3: Estimate the duration of each task Step 4: Draw a network diagram Step 5: Identify the critical path Step 6: Calculate the float Step 7: Monitor the critical path...

Rules for Designing the Activity-on-Node network diagram:

A project network should have only one start node A project network should have only one end node A node has a duration Links normally have no duration “Precedents” are the immediate preceding activities Time moves from left to right in the project network A network should not contain loops A network should not contain dangles...

Forward Pass in Critical path in project management:

Backward Pass in Critical path in project management:

The backward pass is carried out to calculate the latest dates on which each activity may be started and finished without delaying the end date of the project. Assumption: Latest finish date = Earliest Finish date (of project)....
