Program Evaluation and Review Technique

First Question? (What Project and Identifying Name)

• Task Identification: All project activities are broken down into smaller, manageable tasks.
• Task Sequencing: The order in which tasks must be completed is determined.
• Time Estimation: Three-time estimates are assigned to each task:
• Optimistic time (O): The shortest possible time to complete the task.
• Pessimistic time (P): The longest possible time to complete the task.
• Most likely time (M): The most probable time to complete the task.
• Network Diagram: A visual representation of the project, showing the sequence of tasks and their dependencies.
• Critical Path Analysis: Identifies the sequence of tasks that must be completed on time for the entire project to finish on schedule.
• Probability Analysis: Calculates the probability of completing the project within a specific timeframe.

 

Key Benefits of PERT

• Identifies critical path: Helps focus on the most important tasks.
• Manages uncertainty: Accounts for variations in task durations.
• Improves project planning and control: Provides a structured approach to project management.
• Facilitates communication: Visualizes project dependencies and timelines.

 

 

 

 

 

 

 

 

CPM

While PERT focuses on time estimation and probability analysis, CPM (Critical Path Method) emphasizes the determination of the critical path and resource allocation. In practice, PERT and CPM are often used together.

Critical Path Method (CPM): This is a project management technique used to identify the sequence of activities that directly impact the project's overall duration. It's often used in conjunction with PERT.

1. Task Identification: All project activities are broken down into smaller, manageable tasks.
2. Task Sequencing: The order in which tasks must be completed is determined.
3. Time Estimation: A single, most likely time estimate is assigned to each task.
4. Network Diagram: A visual representation of the project, showing the sequence of tasks and their dependencies.
5. Critical Path Analysis: Identifies the longest sequence of tasks (critical path) that determines the project's overall duration.
6. Resource Allocation: Assigns resources based on task dependencies and critical path activities.

 

Key Benefits of CPM

• Clear project timeline: Provides a visual representation of the project schedule.
• Focus on critical activities: Identifies tasks that directly impact project duration.
• Efficient resource allocation: Optimizes resource utilization.
• Risk management: Helps identify potential bottlenecks and delays.
• Cost control: Enables better cost estimation and management.
