How do you develop metrics for a project?

Question

Start from the outcome the project exists to deliver, then work backward to
things you can measure. A practical sequence:

1. Anchor on the “why.” Write the goal as a change in the world, not an
activity. “Launch the new checkout” is an output; “reduce checkout abandonment”
is an outcome. If stakeholders can’t agree on this sentence, metrics won’t fix
it, so settle it first.

2. Pick one primary success metric. This is the number that tells you whether
the project worked (e.g., conversion rate, p95 latency, cost per transaction).
One metric forces clarity; five “primary” metrics let everyone declare victory.

3. Add leading indicators. The primary metric often lags by weeks or months.
Leading indicators are earlier signals that you’re on track: adoption rate,
feature usage, experiment results, error rates in canary. These are what you
manage to week to week.

4. Add guardrail metrics. These catch the damage you might do while chasing the
goal. If you’re optimizing speed, guard on error rate and cost; if you’re
pushing adoption, guard on support tickets and churn.

5. Track execution health separately. Delivery metrics (milestones hit, scope
change, burn-down, dependency risk) tell you whether the program is healthy, not
whether the product succeeded. Keep the two apart so on-time delivery doesn’t
get mistaken for impact.

6. Make each metric operational. For every metric, define:

* Exact formula and data source

* Baseline (measure before you ship, or you can’t show change)

* Target and timeframe, ideally agreed with the business owner

* Owner and review cadence

7. Validate before committing. Ask: can we actually instrument this? Is it
something the team can influence? Could it be gamed? Would a change in it
actually change a decision? If not, drop it.

8. Review and adjust. Revisit at milestones. Retire metrics nobody acts on, and
be explicit when targets change and why.

A compact example: for an app performance project, the primary metric might be
p90 cold-start time, leading indicators would be the share of users on the
optimized build and per-release regression counts, guardrails would be crash
rate and battery usage, and execution health would be milestone status across
the platform teams involved.
