Step 1 — Write the outcome
One sentence, observable, customer-side. 'The customer has completed the core task themselves, once, without help.' Not sessions delivered, not documents sent, not a signed acceptance form.
Test it against the last five customers. If you cannot say confidently whether each reached it, the sentence is not observable enough yet.
Step 2 — Build the milestone spine
Four to six milestones. Each carries an owner, a target day, an exit condition and a defined slip action. Fewer is better: six milestones the team completes beats twelve steps the team half-completes.
| Field | Purpose |
|---|---|
| Name | What is achieved, phrased from the customer's side |
| Owner | One named role accountable for reaching it |
| Target day | Days from start, not a calendar date |
| Exit condition | How anyone can verify it is genuinely complete |
| Required input | What must exist before this milestone can start |
| On slip | The specific action when the target day passes |
Step 3 — Fix the front door
Most onboarding delay originates before onboarding starts. The sales-to-delivery handoff decides whether day one begins with work or with discovery.
- Scope and deliverables as sold, in writing, attached to the record.
- Named customer sponsor and day-to-day contact, with roles.
- Anything promised verbally during the sale, captured explicitly.
- Access, data and dependencies listed with an owner on the customer side.
- Start date agreed with the delivery owner before it is communicated.
Step 4 — Instrument, then run
Represent milestones in the system of record
Dated tasks or stages on the customer record. Not a spreadsheet, not a project tool nobody else opens.
Alert on the slip, to someone with authority
Target day passed without exit condition met, routed to whoever can reallocate capacity or contact the sponsor.
Review weekly by exception
Only accounts with slipped milestones or unresolved blockers reach the agenda. Everything else is fine by definition.
Close with a real handover
A short document: what was delivered, what remains open with owners and dates, who owns the relationship now, and the ongoing cadence.
Step 5 — Improve from the pattern
After ten to fifteen customers, one milestone will dominate the slip statistics. That is the design defect, and it is usually upstream: incomplete handoff input, a dependency the customer cannot supply that fast, or a target day that was never realistic. Fix the design rather than reminding the team to try harder.
- Time to value
- Days from start to the outcome sentence being true. The onboarding metric that predicts retention.
- Milestone slip rate
- Share of customers missing at least one target day. Design signal, not a performance rating.
- Handoff rejection rate
- How often delivery rejects an incomplete handoff. Rising is healthy at first; falling later means the front door improved.
- Open items at handover
- How much unfinished work leaks into steady state. Should trend to near zero.
