What Is Slack and Float in Project Management and How to Manage Them

date icon

In project management, “float” or “slack” is the amount of time a task can be delayed without affecting the deadlines of subsequent tasks or the project’s final delivery date. The former is called “free float”, and the latter is called “total float”. Besides, there are two popular tools carrying the same names. Read this article till the end to learn more about these apps and their key functionality.

How Do I Find Float?

The simplest way to compute slack is to subtract the time you’ve allotted to complete a task from the time the task actually takes. For example, if you’ve allotted 10 days for a task, but it only takes you 6 hours to complete, your slack is 4 days. Tasks with zero floats can be considered part of the “critical path” because any delay on these tasks means a delay to the project deadline itself.

To compute the total float, you need to add up the free float of all the other tasks in the project. If the number is positive, you have that much room to finish a project in case of delays or problems. If the number is negative, you don’t have enough time for the project, and it will most likely miss the deadline.

How Can I Maximize Float?

In order to maximize float in project management, you need to identify your critical path and calculate the amount of float in each non-critical task path. It will help if you visualize the project using a Gantt Chart or PERT diagram.

Gantt Chart is a bar chart that illustrates the project plan based on its tasks and timelines.

With these tools, you can reshuffle tasks and consolidate all of your non-critical tasks into as few task chains as possible. You can then reassign resources and work schedules to focus on the critical chain and to increase team productivity and efficiency. It may not change the amount of float, but it will get you the most out of those spare hours.

Make sure you revise your float estimates as the project goes on. If one task takes longer than expected, you have the option of using up estimated float from a task further down the calendar. Some project managers add a little bit more float than necessary as a safety measure against unexpected delays.

Of course, there will be circumstances where your project gets delayed, no matter how well you manage your float time. Learn from these delays and account for them the next time you schedule a project.

Slack and Float Apps in Project Management: Are They Useful?

So are these applications useful in project management? For sure! Each tool solves its own tasks. If you need a dedicated solution to help you ease out the project management process, it’s better and easier to choose a multifunctional tool to cover the full cycle of project delivery.
