1. What is float in a project schedule?
Float refers to a person assigned to a project but not assigned to a task. That person “floats” between tasks.
Float is extra time available to accomplish a task before that task impacts some other aspect of the project schedule, such as the end date.
Float is the amount of extra time that is embedded in a project estimate to account for uncertainty.
2. What project scheduling technique is used to calculate the amount of float?
The Earned Value Analysis technique.
The Responsibility Accountability Matrix, or RACI Matrix.
The Critical Path Method technique.
3. What is the difference between total float and free float?
Total float is the sum of all task-level float throughout the project. Free float is the float provided to the project by the stakeholders in the Project Charter.
Total float is the sum of all task-level free float for a path within the network diagram. Free float is the task-level float that represents time available before the task impacts the end of the project.
Total float is float available to a task before it impacts the end date of the project and free float is the float available to a task before it impacts another task.
