A Time-to-Value Event Timing Specification
Specify four things: the start event (account creation, first login, or first session — they differ by days for self-serve and by weeks for sales-led), the value event (the single action that means the product worked for them, not a proxy like 'completed onboarding'), the exclusion rules (test accounts, users who never returned after signup, accounts created by your own team), and the statistic (median, not mean — a handful of accounts that activate after six months will drag a mean into meaninglessness). Then report the distribution alongside the headline, because a median of three days made up of half the users in one hour and half in a week is two different products.
Time-to-value appears in board decks and onboarding reviews with no shared definition, which means two teams can report different numbers for the same product and both be right. The specification takes an hour and ends the argument.
Put it into practice
1. Choose the start event and justify it
Account creation measures your whole funnel including activation friction; first login measures the product experience. Both are defensible; pick one, write down why, and keep it stable.
2. Pick a value event that would survive a customer interview
The action a user would describe as 'it worked'. 'Finished the checklist' is a proxy for your process, not their value — if the two differ, measure theirs.
3. Write the exclusion rules
Internal accounts, obvious tests, and users who never returned after signup. Excluding the never-returned group changes the number significantly, so state the choice rather than letting the query decide it.
4. Use the median and show the distribution
Means are wrecked by long-tail activations. Publish the median with the 25th and 75th percentiles so the shape is visible.
5. Segment before drawing conclusions
Self-serve versus sales-assisted, plan tier, and use case. A single blended number usually hides two populations with different journeys and different fixes.

Copy this structure into your review document and record your observed result for each row.
| Decision | Options | Chosen | Rationale |
|---|---|---|---|
| Start event | signup / first login / first session | ||
| Value event | the action meaning 'it worked' | ||
| Exclusions | internal, test, never-returned | ||
| Statistic | median + IQR | median + IQR | means distort |
| Segmentation | self-serve vs assisted, plan |
A failure worth checking
The proxy value event: time-to-value is defined as completing the onboarding checklist, so the team optimises the checklist and the number improves every quarter while renewals do not move. They measured their own process getting faster, not customers reaching value — and the metric actively rewarded shortening the checklist rather than helping anyone.
Common questions
Should time-to-value include weekends?
Use calendar time for the headline, because that is what the customer experiences. Business-hours variants are useful for diagnosing sales-assisted flows and should be reported separately if at all.
What if different segments have different value events?
Then report per segment with each definition stated. One blended number across genuinely different use cases is less useful than two honest ones.
