Planning and dependencies
- A dependency means one task needs something from another before it can proceed. Write the dependency explicitly rather than assuming every task can run in parallel.
- A useful task description states the output, owner and deadline. A measurable outcome makes it possible to check whether the task is complete.
- An estimate is a planning assumption, not a guarantee. Allow for uncertainty and update the plan when a dependency or available resource changes.
Worked example
Proofreading takes one day and must finish before a two-day print job begins. With no gap between tasks, what is the shortest total duration?
- The print job depends on completed proofreading.
- The tasks cannot overlap under the stated rule.
- Add the durations: 1 + 2 = 3 days.
3 days
Watch for: Starting a dependent task before its prerequisite is finished. Treating a vague activity such as improve service as a measurable output.
