In project management, Task Dependency refers to the logical relationship between tasks that determines the sequence in which they must be executed. Some tasks are interdependent, meaning one cannot start or finish without another task reaching a specific stage. Understanding dependencies is crucial for creating accurate project schedules, ensuring that tasks flow smoothly, and avoiding bottlenecks that could delay project completion.
Types of Task Dependencies:
- Finish-to-Start (FS): Task B cannot begin until Task A is completed. (Most common dependency)
- Start-to-Start (SS): Task B can only start when Task A starts.
- Finish-to-Finish (FF): Task B can only finish when Task A finishes.
- Start-to-Finish (SF): Task B cannot finish until Task A starts. (Least common)
Importance of Managing Dependencies:
- Ensures logical task sequencing.
- Prevents bottlenecks and delays.
- Aids in resource allocation.
