Does a business need a CPM and a PERT? Explain. (500 words)

Introduction (100 words)
- Point out that CPM and PERT are two important tools in planning and controlling projects.

Comparing CPM and PERT (250 words) (I am sharing only one sentence to clarify the written output) CPM is widely used in construction and other industries, while PERT is commonly applied in technology, aerospace, and other complex projects.
- CPM employed for projects where activity lengths are given; creating a critical path to concentrate the efforts.
- Uncertainty in project duration is one of the PERT cases; probability statement on deadline is its output.

- CPM generates a Gantt-chart which is prone to fluctuations; PERT finds opportunities where CPM cannot be applied.
- Not excluding them it is also breaking down projects into activities, is using network diagrams as well as identifying critical path.

When to Use CPM and PERT: A quick (100 words)sentence.
- CPM is good option for typical projects in case the complexity of the project and the time/resource estimates are reasonable.
- PERT is the best for a complex, irregular project that involves a lot of unknown variables.

Market for enterprise (50 words)
- The majority of firms would need a combination of CPM and PERT methods unless the work schedule is quite straightforward.

Rationale (200 words)
- Projects, even some regular ones, have some underlying uncertainty.
- Companies on occasion play a role of dealing with projects that are either straightforward or have multi-level complexities.
- CPM and PERT are used interchangeably as they allow the planner to use the planning methodology more flexibly.
- Combination gives realistically-based timeframes, discloses consequences, and demonstrates the interdependence of various project activities therefore.

Conclusion (100 words)
- Briefly explain through project the management metrics of CPM and PERT to make a business to plan every level of complexity and future projects.
