Activity duration estimation plays a crucial role in determining the critical path and float time during project planning. Accurate estimates are essential for identifying the critical path, which is the longest sequence of activities that must be completed on time for the project to be completed on schedule. Inaccurate estimates can lead to delays and impact the critical path. Float time, which is the amount of time an activity can be delayed without impacting the project schedule, is also dependent on accurate activity duration estimates.
To ensure accurate estimates, it is important to define the work breakdown structure (WBS) and identify the activities and their sequence. Resource allocation and leveling should also be considered to ensure that resources are properly assigned and not over-allocated. Milestones should be identified to mark progress towards project completion, and risks should be managed and contingency plans developed to mitigate potential issues. Schedule compression techniques can be used to shorten the project schedule without impacting the critical path, but improper use can lead to quality issues and cost overruns. Time constraints should also be considered when developing the project schedule. Regular review and updates of the project schedule are necessary to ensure accuracy and avoid delays and cost overruns.

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Critical path and float are the same thing. | Critical path and float are two different concepts in project planning. The critical path is the longest sequence of tasks that must be completed on time for the project to finish on schedule, while float refers to the amount of time a task can be delayed without affecting the overall project timeline. |
| Float is not important in project planning. | Float is an essential concept in project planning as it helps identify which tasks have flexibility in their timelines and which ones do not. This information can help with resource allocation, risk management, and decision-making during the execution phase of a project. |
| Only activities on the critical path need to be closely monitored. | While activities on the critical path require close monitoring, other non-critical activities may also impact overall project performance if they experience delays or changes in scope or resources allocated to them. Therefore, all activities should be monitored regularly throughout a project’s lifecycle regardless of whether they are part of its critical path or not. |
| A shorter critical path always means less risk for a project. | A shorter critical path does not necessarily mean less risk for a project since it could still contain high-risk tasks that require careful management and mitigation strategies to ensure successful completion within their allotted timeframe. |
| Once identified, the critical path cannot change during a project’s lifecycle. | The critical path can change during a Project’s life cycle due to various factors such as unexpected events like weather conditions or supply chain disruptions that affect task durations or dependencies between tasks being re-evaluated based on new information gathered from stakeholders‘ feedback about progress made so far towards achieving goals set out at inception stage etcetera . It is therefore crucial always to review your plan periodically against actual results achieved so far along each activity line item listed therein before making any adjustments where necessary going forward until final delivery date. |
