1. Re-pull a trailing 12 months of won, lost, and churned outcomes
A refresh starts with new evidence, not last year's charts. Export every closed-won, closed-lost, and churned or heavily-contracted account from the last 12 months, snapshotted with the firmographics as they looked at opportunity creation rather than enriched today. Include industry, employee count, revenue band, geography, tech stack, buying committee size, acquisition channel, sales cycle length, ACV, gross margin, and 12-month net retention. Line it up next to last year's pull so cohort sizes and win rates are directly comparable. The three cohorts answer the three questions the refresh needs to settle: who still buys, who no longer buys, and who buys but churns.
- Export closed-won with firmographics frozen at opportunity creation, not today.
- Export closed-lost with loss reason, stage of death, and competitor if captured.
- Export churned and down-sold accounts with churn reason and tenure at churn.
- Lay the pull next to last year's cohorts so year-over-year drift is readable.
Tip: If enrichment vendors changed mid-year, re-run the pull with both the old and new enrichment snapshots so you can tell which drift is market signal and which is tooling noise.

2. Recompute lift on every existing ICP dimension
Take each dimension from the current ICP and recompute its win-rate lift and retention lift against the new 12-month pull. A dimension that was pulling 1.8x last year and now runs at 1.1x is drifting toward noise. A dimension that still clears 1.5x is a keeper. Score both win-rate lift and retention lift separately so you catch the dimensions that still close fast but churn in month 11. Keep the sample size behind every number visible so a reviewer can tell which lift is signal and which is a small-cell artifact. The output of this step is a single ranked table of existing dimensions by current lift, with the delta against last year called out.
Tip: Any dimension that drops below 1.3x lift this year is on probation. Any that drops below 1.0x in both win rate and retention is a retirement candidate, not a keeper.

3. Mine the new data for emerging patterns and buyer-title evolution
The refresh is not just a scorecard on last year's profile; it is a search for what has started working that was not in the profile at all. Re-cluster the fresh won and expansion cohorts and look for traits with 1.5x lift or higher that are not already in the ICP. Pay particular attention to buyer-title evolution: the champion role that closed deals last year may have been replaced by a different title, a committee may have grown or shrunk, or a new economic buyer may have appeared. Watch for use-case patterns too: a feature shipped mid-year may have unlocked a new vertical that is now punching above its weight. Flag every new candidate dimension with its lift, cohort size, and a one-line hypothesis for why it works.
- Re-cluster winners and expansions on all attributes, not just the current ICP ones.
- Compare buyer titles, committee size, and economic buyer against last year.
- Isolate use-case patterns that correlate with features shipped during the year.
- Score every new candidate dimension on win-rate lift and retention lift before promoting it.

4. Identify firmographic shifts in your winning cohort
Markets drift and the shape of your winner drifts with them. Compare this year's winning cohort to last year's on every firmographic axis: are you winning smaller or larger accounts, moving upmarket or downmarket, expanding into new geographies, winning in verticals you did not previously target, or losing ground in a stronghold vertical? Firmographic shifts rarely show up as a single trait change; they usually appear as a composite. A size band that grew by 20 percent of your wins paired with a new vertical mix and a longer sales cycle is a signal that your motion itself is shifting, not just the profile. Document each shift with the delta, the suspected cause, and whether it should harden into the next ICP or stay on watch for another quarter.
Tip: Separate signal from noise by requiring at least two consecutive quarters of movement before promoting a firmographic shift into the official ICP.

5. De-ICP the cohorts that stopped working
The hardest part of a refresh is removing dimensions and segments that were in last year's ICP. A de-ICP decision is a formal retirement of a dimension, vertical, size band, or buyer motion that no longer earns its spot. Pull every cohort that fell below 1.0x on both win rate and retention lift and write a short retirement memo for each: what it was, why it worked once, what changed, and what the team should do with the pipeline that still sits inside it. Add the retired cohort to the anti-ICP with a clear disqualification line so BDRs stop sourcing it, marketing stops targeting it, and CS stops staffing new onboarding plays for it. De-ICPs protect capacity for the dimensions that still earn their keep.
- List every dimension, vertical, or size band below 1.0x on win and retention lift.
- Write a one-page retirement memo for each with cause and current pipeline exposure.
- Move the retired cohort into the anti-ICP with an explicit disqualification line.
- Decide whether in-flight pipeline inside the retired cohort runs to close or gets reassigned.
Tip: If sales leadership resists a de-ICP, offer a six-month sunset where the cohort is still allowed in pipeline but no new target lists, campaigns, or SDR capacity point at it.

6. Publish the refreshed ICP with a year-over-year changelog
A refresh that lands as a Slack message disappears by Monday. Publish the new ICP as a one-page artifact with the full year-over-year changelog beside it: dimensions kept, dimensions retired, new dimensions added, buyer-title changes, firmographic shifts, and the anti-ICP additions. Show the lift numbers behind every call so a skeptical rep or marketer can audit the math. Version the document so anyone can diff this year against last year. Link it from every GTM template that depends on the ICP: the sales qualification script, the marketing brief, the demand-gen target list, the CS onboarding plan, and the territory design doc. If a new hire cannot read the artifact in 10 minutes and tell you what changed, the changelog is too long.
Tip: Keep the main artifact one page and push the lift math into a linked evidence sheet. The changelog is the thing GTM reads; the sheet is the thing a skeptic audits.

7. Reset target lists, lead scoring, and sales plays against the new ICP
The refresh only matters if it changes what shows up in a rep's queue on Monday. Rebuild the target account list against the refreshed dimensions, both inside the CRM and in whatever outbound tooling the SDR team runs. Reweight the lead scoring model: dimensions that gained lift get more points, retired dimensions move to zero or negative, and new buyer titles enter the scoring table. Update sales plays so the discovery, qualification, and disqualification language reflects the new buyer evolution and the de-ICP cohorts. Marketing rebuilds segments, paid-media audiences, and nurture tracks against the same list. CS updates onboarding plays and health-score inputs against the retention lift findings. Lock the next quarter plans to the refreshed ICP so nothing in-flight quietly runs against the old profile.
- Rebuild the CRM target account list and outbound tooling filters against the new dimensions.
- Reweight the lead scoring model with new dimensions in and retired dimensions out.
- Rewrite sales qualification, discovery, and disqualification scripts for the new buyer evolution.
- Reset marketing segments, paid-media audiences, and nurture tracks against the refreshed ICP.
- Update CS onboarding plays and health-score inputs against the retention-lift evidence.

8. Retrain GTM and lock the next review date
A refreshed ICP that does not get retrained against is a document, not a program. Run a working session with each GTM function the week the artifact ships so sales, marketing, demand gen, SDR, and CS all walk through the changelog, the new dimensions, and the retired cohorts out loud. BDRs practice the new disqualification lines for the de-ICPs so the cuts stick on live calls. Marketing presents the new target lists back to sales for sign-off. CS presents the new onboarding plays back to the account team. Then lock the next refresh date on the calendar: a quarterly lift re-check and a full annual refresh with named owners for each. Treat the ICP like production code: versioned, reviewed, owned, and backtested every release.
- Hold a working session with sales, marketing, demand gen, SDR, and CS the week after publish.
- Rehearse the new disqualification lines for every de-ICP cohort out loud with BDRs.
- Walk the new target lists and sales plays back through sales leadership for sign-off.
- Put the next quarterly lift check and next annual refresh on the calendar with named owners.
Tip: If no one owns the next refresh on the calendar, the current refresh starts rotting the day it ships. Name a RevOps owner and a product marketing co-owner before the working session ends.
