What is the critical path?

The longest chain of dependent tasks that determines the earliest project finish date. Delays on the critical path delay the project; tasks with float can slip without moving the end date.

What is float or slack?

Float is how long a non-critical task can delay without pushing the project end date. Zero float means the task is on the critical path.

Do I need software to find the critical path?

Small schedules can be traced by hand; most teams use planning tools once dependencies multiply. The value is keeping dependencies current as the plan changes.

Can PMHub show dependency chains?

Blueprint includes dependency chain views alongside Gantt-style timelines so you can see driving relationships on Pro plans.
