Task Dependencies
Define relationships between tasks to manage the order of work. Dependencies show which tasks must finish before others can start.
Dependency Types
| Type | Code | Meaning |
|---|---|---|
| Finish-to-Start | FS | Task B can’t start until Task A finishes |
| Start-to-Start | SS | Task B can’t start until Task A starts |
| Finish-to-Finish | FF | Task B can’t finish until Task A finishes |
| Start-to-Finish | SF | Task B can’t finish until Task A starts |
Finish-to-Start (FS) is the most common dependency type. For example: “Design must finish before Development can start.”

Viewing Dependencies
Blocking & Blocked
Each task shows:
- Blocking — Tasks that can’t proceed until this task is done
- Blocked by — Tasks that must complete before this one can start
Gantt Chart
Dependencies are visually represented as arrows on the Gantt Chart, making it easy to see the workflow sequence.
Critical Path
The critical path identifies the chain of dependent tasks that determine the minimum project duration.
Circular Dependency Protection
Tickmark automatically checks for circular dependencies (A → B → C → A) and prevents them from being created.
