Definition
Start-to-Start (SS) is a type of task dependency where one task (Task B) cannot start until another task (Task A) has started. However, Task A does not need to finish before Task B begins.
Example:
Imagine building a house:
- Task A: Pouring the foundation.
- Task B: Installing plumbing.
Plumbing installation can start as soon as the foundation pouring begins—it doesn’t have to wait for the foundation to be fully dry.
Why It Matters:
- Helps manage parallel workflows.
- Increases efficiency in complex scheduling.
- Optimizes project timelines by reducing idle time.
SS dependencies are commonly used in construction, manufacturing, and Agile software development where multiple processes run simultaneously.
