Difference Between CPM and PERT

Program Evaluation and Review Technique (PERT) and Critical Path Method both are project schedule development and analysis techniques. Both these techniques establish the critical path in a schedule network diagram. However, both CPM and PERT use different approach to arrive at the critical path and activity duration estimates. The following blog post highlights difference Between CPM and PERT. Read More

Project Management Formulas

There are a number of project management formulas to perform quantitative analysis, but from pmp exam point of view there are a few important ones. Key areas such as Earned Value Analysis, Critical Path Analysis, and Procurement Management require use of Quantitative skills. Hence, this post enumerates important mathematical formulas required for Project Management Professional (PMP) certification exam. Read More

Program Evaluation And Review Technique

Program Evaluation and Review Technique (PERT) is a project schedule development and analysis technique that represents a sequence of activities and activity relationship in a graphical format. PERT uses Arrow Diagram Method (ADM) technique to construct the network diagram. Activity-on-Arrow is an example of ADM method. PERT uses three-point estimation technique to arrive at the estimated duration. Read More

Schedule Network Analysis Methods

Project schedule network analysis is an analytical technique to identify critical path in a schedule network diagram and generate critical activities. It further specifies the degree of schedule flexibility in a given network logic. The output of schedule network analysis is a schedule model. This project schedule model serves as a basis for project execution, analysis, controlling and reporting. Read More

Project Schedule Development Process

Project schedule development process is an iterative process and continues through out the project as work progresses. Project schedule is updated as the duration, resource estimates change on account of changes to project scope and budget. Anticipated risks may occur or disappear and this may also result is updating the project schedule. Before we start… Read More
