This document provides information on project management techniques PERT and CPM. It defines them as quantitative network analysis techniques used for decision making. PERT is a probabilistic model used for non-repetitive projects like program planning, where activity times are uncertain. CPM is a deterministic model used for repetitive projects like construction, where activity times are known. The document outlines the key steps and uses of PERT/CPM, including planning, scheduling, resource allocation, controlling, and developing network diagrams to analyze tasks and represent relationships between activities.

2. Combination of inter related
activities
Executed in logical sequence
Accomplishment of a desired
objective

3. The emphasis was on completing the
program in the shortest possible time
Developed By the US navy for planning
and control of Polaris missile program
PERT
The emphasis was on the trade-off between
the cost of the project and its overall
completion time
Developed by DU Pont to solve project
scheduling problems
CPM

4. Uniform wide acceptance
Performance evaluation
External program review
Internal program review
Controlling resource allocation
Planning resource requirements
Prediction of deliverables

5. Construction of a Dam or Canal
Construction of a building or highway
Maintenance or Overhaul of aircrafts
Space Flights
Designing a Prototype of a Machine
Development of Supersonic Planes

6. 1. PLANNING
2. SCHEDULING
3. ALLOCATION OF RESOURCES
4. CONTROLLING

7. Use the Network to help plan, schedule,
Compute the critical path.
Assign time and/or cost estimates to each activity
Draw the "Network" connecting all the activities.
Develop the relationships among the activities.
Define the Project. The Project should have only a single start activity and a single finish activity.

8. Drafting the design of
Programme or Project
Project Evaluation of drafted
Programme or Project
Project Review of evaluated
Programme or Project

9. To analyze and represent the tasks
involved in completing a given project
Accommodates the variation in event
completion time
Event-oriented technique rather than
start- and completion-oriented
Commonly used in conjunction with the
critical path method

10. Activity
Event
Constraints
Network
Diagram
Critical Path

12.  Both are Quantitative Techniques of Network
Analysis
 Both are used as tools for Decision Making
 Both involve drawing & analysis of Network
Diagram on various scores

13. PERT
Probabilistic Model
Non-repetitive jobs like
planning scheduling of
programmes
Results calculated on basis of
Event
Related with activities of
uncertain time
CPM
Deterministic Model
Repetitive jobs like
residential construction
Results calculated on
basis of activities
Related with activities of
well known time

14. Reduction in
cost
Elimination of Risk
in Complex activity
Flexibility
Optimization of Resources
Reduction of Uncertainties

15. Network charts tend to be large
Lack of a timeframe on most PERT/CPM charts makes it
harder to show status
When PERT/CPM charts become unwieldy, they are no longer
used to manage the project
Planning & Implementation required
