The 100-Day Integration Velocity Score

How to apply

Step 1

Identify the six measurement dimensions

Consolidated billing, single SSO, merged engineering on-call, combined CRM, unified incident response, shared compensation framework.

Step 2

Set the day-zero baseline

Capture the as-of state at deal close. For each dimension, mark whether the dimension is unified, partially unified, or operating in parallel.

Step 3

Track days-to-completion against the cohort

For each dimension, log the day on which it transitions to unified. The Velocity Score combines completion percentage and pace-vs-cohort into a single 0–100 metric.

Step 4

Re-score weekly during the 100 days

Weekly cadence is the operating-partner reporting frequency. Trend lines reveal which dimensions are slipping and which are ahead of plan.

Step 5

Compare against retention outcomes

At day 180, compare the day-100 Velocity Score against actual customer and staff retention. Calibration data flows back into the cohort dataset for the quarterly refresh.

PE Operating Partners running 100-day plans need a measurable number, not status updates. Status updates are how integrations fail without anyone noticing until day 90, when the LOI assumptions are already in retreat. The 100-Day Integration Velocity Score exists because we got tired of writing post-mortems on integrations that “felt fine in week six” and produced 80% retention at day 180.

What the score predicts

The Score is calibrated against Human Renaissance integration engagements where we tracked both the day-100 metric and the day-180 retention outcomes. The correlation is consistent: Velocity Score above 75 at day 60 produces customer retention above 95% at day 180. Velocity Score below 50 at day 60 produces customer retention below 85%, regardless of what the headline status report claimed at the time.

The six dimensions

Each dimension has a published cohort benchmark in days-to-completion. The cohort is the anonymized aggregate of Human Renaissance engagements, refreshed quarterly. Dimensions are weighted differently — single SSO and merged engineering on-call carry the most retention signal because they touch end-user experience and engineering attrition simultaneously.

The cohort dataset

The aggregated benchmarks ship at /research/turnaround-index-2026 (Tech Middle-Market Turnaround Index) with a downloadable CSV and methodology page. Individual engagement data stays confidential.

Where the Score gets used

In every Migration & Integration engagement, the topic hub for which is here, and in every Performance Improvement engagement that touches a recently-acquired entity. We measure it weekly, surface trend lines in the Operating Partner dashboard, and use it to escalate weeks before the integration would otherwise show up as a problem.

Frequently asked

What does the Velocity Score measure?

Six dimensions of post-close integration speed: days to consolidated billing, days to single SSO, days to merged engineering on-call, days to combined CRM, days to unified incident response, days to shared compensation framework. Each dimension is benchmarked against the anonymized Human Renaissance cohort.

Why 100 days?

100-day plans are the standard PE operating-partner cadence. Velocity Score measurement at days 30, 60, 90, and 100 produces a leading indicator for whether the integration will hit the 180-day retention numbers buyers underwrote.

What's a healthy Velocity Score?

A Velocity Score above 75 (out of 100) at day 60 correlates with the 95%+ post-merger customer retention bands in the Human Renaissance cohort. Below 50 at day 60 is an early-warning signal that the integration plan needs to be re-architected — typically by replacing the integration management office leadership or adding interim capacity.

Is the cohort dataset public?

The cohort is anonymized and refreshed quarterly. The aggregated benchmarks (median days, percentile ranges) are public. Individual engagements remain confidential under our advisory engagements.
