What is Float? And, What is Slack? in Project Management

In this video, I will answer the question, what is float? Or, if you prefer, what is Slack? (not the software)
Float as schedule flexibility
It is the amount of time a project activity can slip before it has an adverse effect on another scheduled activity
Float = slack
Some people reserve float to mean how long you can over-run a task without implications. They use slack to refer to how long you can delay the start of a task without implications.
Free float
The amount of time that a scheduled activity can be delayed without affecting the start of successor activities - aka task float or activity float
FF = ES(b) - EF(a)
Total float
The amount of time that a scheduled activity can be delayed without affecting the end of the project - aka project float.
TF = LF - EF or LS - ES
Project float can also refer to the amount of time a project can be delayed without affecting the end-user or client
Negative float
If your project will be delayed, this is the time between when you can finish a task and when you need it finished to assure completion on schedule.
Critical Path
Longest path through a network. Will have the least float - possibly zero
All activities on the critical path should have zero float - UNLESS you schedule in float as a deliberate risk mitigation measure
