Critical Path
Think of it as your project's backbone—the sequence of must-complete tasks that sets your absolute fastest completion time. Miss a deadline here, and your whole project timeline shifts.
Slack/Float
Your breathing room. It's how much you can delay a task before it starts affecting when your project wraps up. Tasks on the critical path? They have zero wiggle room.
Dependency (FS, SS, FF, SF)
Relationships between tasks. FS (Finish-to-Start): most common, task B starts after A finishes. SS (Start-to-Start): both start together. FF (Finish-to-Finish): both finish together. SF (Start-to-Finish): rare, task B finishes when A starts.
Gantt Chart
A visual project management tool showing tasks as horizontal bars along a timeline, illustrating start dates, durations, and dependencies.
Milestone
A significant point or event in the project, typically with zero duration, marking the completion of a major phase or deliverable.
Early Start/Finish
The earliest possible time a task can start or finish based on predecessor dependencies.
Late Start/Finish
The latest time a task can start or finish without delaying the project completion.
🧮 Critical Path Formulas
▼
Early Start (ES)
ES = Max(Predecessors' Early Finish)
Early Finish (EF)
EF = ES + Duration
Late Finish (LF)
LF = Min(Successors' Late Start)
Late Start (LS)
LS = LF - Duration
Total Float/Slack
Float = LS - ES = LF - EF
Critical Path Condition
If Float = 0, then task is on Critical Path
