# 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

# Project Selection Methods Top 5 Criteria

Project selection methods have a vital role during project initiating phase. In fact during the project selection process a project manager rarely has any involvement. However, knowing the essentials of the project selection process adds value to the overall project execution. Moreover, those aspiring for the pmp certification examination need to know the basics of project selection criteria. 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

# Earned Value Management Challenges

Earned value management system is a robust methodology to integrate schedule, scope, and cost baselines of a project. EVM is an analytical tool that also uses variances to track schedule and cost performance of a project. It further uses efficiency indicators to forecast project health. Though EVM analysis offers numerous benefits, implementing this technique offers some challenges. Read More

# Variance Analysis In Project Management

Project variance analysis is an important technique that allows project teams to constantly compare planned performance with actual project data. Hence, it assists project teams in identifying and analysing deviations in project performance. In simple terms, variance analysis is the variation between plan and actual project performance. It further helps to identify causes and assess severity of deviation. Read More
