Applying low and high estimates

Can I apply uncertainty (Low, Most Likely, High values) to a group of tasks, and how does it work with summary tasks?

Yes. You can apply uncertainty to:

Individual activities

Groups of activities

If applied to a summary task, the uncertainty will automatically apply to all subtasks beneath it.

Best Practices

Use summary tasks for bulk adjustments when tasks share similar uncertainty characteristics.

Avoid applying uncertainty at both summary and subtask levels simultaneously—this can create confusion.

Group tasks logically (e.g., by phase or deliverable) before applying uncertainty.

Validate that grouped tasks truly share similar risk profiles.
