## Learning objectives
- Distinguish activity from a useful outcome.
- Include preparation, review, and correction in a time comparison.
- Recognize the limits of a productivity claim.

## Exercise

## Your response
- Scenario and scope:
- Assumptions and open questions:
- Proposed answer or decision, with reasons:

## Verify your response

- When will you review this response?

## Principle to retain
Measure the complete task at a consistent quality level. A faster first draft can still produce more total work.
