What this question tests
Basic project-execution metric literacy: knowing which schedule metric actually predicts risk versus which just looks reassuring.
How to approach it
- Clarify what 'tight schedule' means here: a fixed launch date with real slip risk.
- Reject vanity metrics like percent of tasks closed, since that hides whether the critical path is on track.
- Propose schedule variance on the critical path: days ahead or behind plan for the sequence of tasks that actually gates launch.
- Pair it with a leading indicator: weekly burn-down rate of remaining critical-path work.
- Add a risk metric: number of open blockers or dependencies past their due date.
- State the guardrail: don't let schedule pressure hide quality, so track defect count alongside.
What a strong answer includes
- Distinguishes critical-path variance from overall task completion, the key insight interviewers look for.
- Gives an example: a 3-day critical-path slip in week 2 of a 6-week project is a bigger signal than 80% of tasks done.
- Mentions blocker aging as an early-warning metric, not just a lagging one.
Common mistakes
- Answering with 'on-time delivery percent' alone, a lagging binary metric with no diagnostic value mid-project.
- Not distinguishing the critical path from all tasks.
Likely follow-up questions
- How would you communicate a 2-day slip to stakeholders?
- What would make you pull the launch date forward as a guardrail?
