Critical Path
The longest sequence of dependent tasks that determines the minimum project duration. Any delay in critical path tasks delays the entire project.
Slack/Float
The amount of time a task can be delayed without affecting the project completion date. Tasks on the critical path have zero slack.
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
