Engagement success is measured against specific outcome metrics agreed in the engagement letter at the start. The metrics vary by engagement type. For market-entry engagements: licence application submitted by X date, first regulator response received without material clarification rounds, day-zero launch metrics meeting plan (FTDs per month, CAC band, day-30 retention).
For CRM rebuild engagements: re-segmentation completed and live by X date, lifecycle programmes redesigned by Y date, measurable improvement in retention at 30 and 90 days inside 12 months. For multi-market sequencing engagements: three markets sequenced and live to plan, no material operating-model failures, unit economics holding up at each stage. Monthly strategic review covers progress against these metrics openly.
Where metrics are not being hit, the conversation is about why and what to do, not about defending the engagement. Engagements that are not producing outcomes get adjusted (scope change, focus shift) or terminated; running an engagement that is not delivering would be dishonest to the operator. The honest framing on measurement: most consulting engagements in the industry are measured on activity (deliverables shipped, hours worked, slides produced) rather than outcomes.
Measurement against pre-agreed outcomes is operator-side discipline. It is harder for both sides because it forces clarity at the start, but it is the only honest way to assess whether the engagement is actually working.
