What is PERT and CPM ?

Project is a task designed to accomplish singular goal . Such as developing software, product .  In project involves some batch work . 

Project Management - 

• Project Planning
• Project Scheduling 
• Project Control 

CPM - Critical Path Method

PERT - Program Evaluation and Review Techniques

1. CPM and PERT are used to project Scheduling.
2. CPM and PERT are network models
3. CPM was developed by ' Du Pont ' in 1950.
4. PERT was developed by 'U S Navy ' in 1950.
5. In beginning CPM was used to design chemical plant . 
6. In beginning PERT was used to Polaris Submarine Launched Missile Project.

CPM :

1. Deterministic Approach
2. Onetime Estimated 
3. Activity Oriented 
4. Float Concept

PERT : 

1. Probabilistic Approach
2. Three times Estimate
3. Event Oriented 
4. Slack Concept

Steps of PERT and CPM :

1. Project Objectives and work breakdown structure ( wbs) 
2. Precedence and Activities
3. Network
4. Time and cost estimates 
5. Longest path - critical path
6. Use the network to plan , schedule , moniter and control the project .
