What is Programme Evaluation and Review Technique (PERT ) ?
Programme Evaluation and Review Technique (PERT) is an effective visual network method specifically designed for planning, monitoring, and controlling complex and unique projects. PERT offers a systematic approach that ensures project success by breaking down the entire project into smaller, manageable activities and establishing their interdependencies within a network diagram.
The process of developing a PERT involves several key steps:
- Activity Breakdown: The project is carefully dissected into smaller activities, enabling a more granular analysis and logical sequencing of tasks.
- Interdependency Identification: The relationships and dependencies between the activities are thoroughly examined and accurately represented in the network diagram, providing a comprehensive view of the project’s structure.
- Time Estimation: Each activity is assigned three-time estimates: the optimistic or shortest time, the pessimistic or longest time, and the normal or most likely time. These estimates facilitate a more realistic assessment of activity durations.
- Critical Path Determination: The critical path, the longest path in terms of time, is identified within the network diagram. It signifies the sequence of activities crucial for timely project completion. Any delays along the critical path directly impact the overall project timeline.
- Plan Refinement: Based on the critical path analysis, the initial project plan is carefully reviewed, modified, and improved to effectively control and minimize the time required for project completion. This ensures that the project stays on track and any potential delays are mitigated.
Techniques of Control- PERT and CPM
Techniques of control are vital for effective management and achieving organisational goals. These techniques include financial control, quality control, inventory control, process control, strategic control, and personnel control. They involve managing financial resources, ensuring product/service quality, optimizing inventory levels, enhancing operational efficiency, aligning with strategic goals, and evaluating employee performance. By employing these control techniques, businesses can maintain quality, efficiency, and profitability for long-term success.
