Total float, also known as project slack, refers to the amount of time a task can be delayed without affecting the completion date of the project. It is a crucial concept in project management as it provides flexibility in scheduling and resource allocation.
Key Facts
- Definition: Total float refers to the amount of time that a task can be delayed without affecting the completion date of the project.
- Calculation: Total float can be calculated by subtracting the early finish date of an activity from its late finish date.
- Critical Path: Total float is used to identify critical activities in a project. Critical activities have zero or negative total float, meaning any delay in these activities will delay the project’s completion date.
- Resource Allocation: Total float helps project managers in resource allocation. Activities with high total float can be delayed, allowing resources to be allocated to critical activities.
- Schedule Flexibility: Total float provides flexibility in project scheduling. It allows project managers to adjust the timing of non-critical activities without impacting the project’s overall timeline.
- Project Control: Monitoring the total float of activities helps project managers track the progress of the project and identify potential delays or bottlenecks.
- Risk Management: Total float is considered in risk management strategies. Activities with low total float are more susceptible to delays and should be closely monitored to mitigate risks.
Calculation
Total float is calculated by subtracting the early finish date of an activity from its late finish date. The early finish date is the earliest possible date a task can be completed, while the late finish date is the latest possible date a task can be completed without delaying the project.
Critical Path
Total float is used to identify critical activities in a project. Critical activities have zero or negative total float, meaning any delay in these activities will delay the project’s completion date. These activities are crucial for the project’s success and require close monitoring and management.
Resource Allocation
Total float plays a significant role in resource allocation. Activities with high total float can be delayed, allowing resources to be allocated to critical activities. This flexibility helps project managers optimize resource utilization and avoid resource constraints.
Schedule Flexibility
Total float provides flexibility in project scheduling. It allows project managers to adjust the timing of non-critical activities without impacting the project’s overall timeline. This flexibility is essential for accommodating changes, unforeseen circumstances, and risk mitigation strategies.
Project Control
Monitoring the total float of activities helps project managers track the progress of the project and identify potential delays or bottlenecks. By keeping track of total float, project managers can take proactive measures to address potential issues and ensure the project stays on schedule.
Risk Management
Total float is considered in risk management strategies. Activities with low total float are more susceptible to delays and should be closely monitored to mitigate risks. Identifying and addressing risks early on can prevent delays and disruptions to the project schedule.
Conclusion
Total float is a valuable tool in project management that provides flexibility, facilitates resource allocation, and aids in project control and risk management. Understanding and effectively managing total float enables project managers to optimize project schedules, minimize delays, and enhance project success.

FAQs
1. What is total float?
Total float is the amount of time a task can be delayed without affecting the completion date of the project.
2. How is total float calculated?
Total float is calculated by subtracting the early finish date of an activity from its late finish date.
3. What is the significance of total float in project management?
Total float provides flexibility in scheduling, resource allocation, and project control. It helps identify critical activities, optimize resource utilization, and mitigate risks.
4. How does total float differ from free float?
Total float considers both the free float and any delay that can occur without delaying the project’s finish. Free float, on the other hand, only considers the flexibility in scheduling non-critical activities.
5. How can total float be used to optimize project schedules?
By understanding total float, project managers can identify non-critical activities that can be delayed to accommodate changes, unforeseen circumstances, or resource constraints. This flexibility helps optimize the project schedule and minimize delays.
6. How does total float aid in resource allocation?
Total float helps project managers allocate resources efficiently. Activities with high total float can be delayed, allowing resources to be allocated to critical activities or activities with low total float. This optimization ensures efficient resource utilization and avoids resource conflicts.
7. How is total float used in project control?
Monitoring total float helps project managers track the progress of the project and identify potential delays or bottlenecks. By keeping track of total float, project managers can take proactive measures to address potential issues and ensure the project stays on schedule.
8. How does total float contribute to risk management in projects?
Total float is considered in risk management strategies. Activities with low total float are more susceptible to delays and should be closely monitored to mitigate risks. Identifying and addressing risks early on can prevent delays and disruptions to the project schedule.
