Difference between Crashing and Fast tracking.
Crashing and Fast Tracking are both schedule compression techniques used in project management to reduce the overall duration of a project. However, they differ in terms of method, cost, risk, and when they are applied. Here’s a breakdown of the key differences between Crashing and Fast Tracking:
| Aspect | Crashing | Fast Tracking |
|---|---|---|
| Method | Involves adding more resources (labor, equipment, or money) to critical path tasks to reduce their duration. | Involves overlapping tasks that were originally planned to be done sequentially, allowing them to be performed in parallel. |
| Cost | Increases costs due to the additional resources needed. | Typically does not increase direct costs but may lead to hidden costs like rework. |
| Risk | Lower risk compared to fast tracking but can still lead to resource overload and diminishing returns if not managed properly. | Higher risk of errors, rework, and coordination issues because tasks may be started before their predecessor is fully completed. |
| Impact on Quality | May affect quality due to rushed work, particularly if too many resources are added too quickly. | More likely to affect quality, as overlapping tasks can lead to errors or unfinished work. |
| Best Use Case | Used when there’s flexibility in the budget but a strict deadline must be met. Best when additional resources can reduce time without excessive cost. | Used when a project needs to finish faster, and tasks can be overlapped without requiring extra resources. Suitable when budget constraints exist but deadlines are tight. |
| Effectiveness | Can be highly effective in shortening the schedule, but only for tasks where adding resources speeds up progress. | Can also be effective but depends on how well the tasks can be overlapped without causing delays or quality issues. |
| Example | Adding more workers to construction or increasing overtime to speed up task completion. | Starting software testing while development is still in progress, or initiating interior work while structural work is ongoing. |
Key Differences:
- Crashing adds more resources to speed up work on critical tasks, resulting in higher costs.
- Fast Tracking overlaps tasks to reduce the timeline, increasing risks and coordination challenges but generally not impacting direct costs as much as crashing does.
Both techniques aim to reduce the project timeline, but crashing focuses on spending more resources, while fast tracking focuses on reorganizing tasks.
