Limitations of PERT/CPM
The following are the limitations of PERT/CPM:
- Estimation Challenges: One of the limitations of PERT/CPM is the inherent difficulty in accurately estimating the time and cost involved in various project activities. Estimation errors can introduce unpredictability and make the PERT chart less reliable as a control tool for effective project management.
- Time-Centric Focus: PERT/CPM is primarily suited for projects where time plays a critical role. It shines in managing and controlling time-sensitive projects, but its applicability may be constrained when other factors, such as cost or quality hold greater significance in project outcomes.
- Limited Applicability to Simple Projects: PERT/CPM may have limited utility in handling straightforward, routine, and repetitive projects. Its strength lies in tackling complex and unique projects that require intricate analysis and involve multiple interdependent activities. In cases of continuous processes or projects with a streamlined and predictable flow, PERT/CPM may not provide substantial advantages.
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.
