Read the brief, then put up to three outputs side by side, each with the LLM judge’s verdict on every check. Highlights mark what a PM had to fix.

The brief

You're a Staff PM at Crate. In four weeks, the exec team decides which of two bets gets our two squads next half, and both bets rest on a theory of why customers are leaving. We have three weeks for 12 customer calls of 45 minutes. Write the guide for them. It should include: the learning goals; the questions, with timings, for the two kinds of people we'll talk to; guidance for whoever runs the calls; any changes you'd make to the plan below; and what we'd need to hear to back each bet, or neither. Keep it under 1,500 words. The exec team will read it before the calls start.

What the model was given8 items: About Crate, The decision, CEO, Ana Ferreira, CPO, Marcus Hill, Exit survey (41 churned customers, last 12 months), Implementation and CRM data, The call plan, Notes from Customer Success and Legal
About CrateWarehouse management software for mid-size third-party logistics companies (3PLs). 340 customers, $22M ARR. Gross logo churn rose from 11% to 18% over the last year.
The decisionBet A: integrations with warehouse robotics (autonomous carts, pick-assist robots). Bet B: rebuild implementation so customers go live faster. Two squads for the next half go to one of them.
CEO, Ana Ferreira“We're losing warehouses because they're automating and we don't talk to their robots. Every lost customer I've spoken to mentions it.”
CPO, Marcus Hill“We lose them in the first year because implementation takes forever. They're gone before they ever see the value.”
Exit survey (41 churned customers, last 12 months)A single-choice question, 'Why are you leaving?'. Missing features or integrations: 46%. Too hard to implement: 22%. Price: 17%. Other: 15% (free-text box, left blank by all but two). 'Missing features or integrations' was the first option in the list.
Implementation and CRM dataMedian time from signing to go-live: 94 days; the contract promises 45. Customers who went live after 90 days churned at 2.4× the rate of the rest in their first year. 3 churned customers moved to a competitor with robotics integrations; robotics was cited in 9 lost new-logo deals. We don't know when in the year churned customers decided to leave.
The call plan12 calls: 6 with customers who churned in the last 9 months, 6 with at-risk customers (health score red). On each account we want to talk to the warehouse operations manager who used Crate every day and, separately, the VP of Operations or COO who signed the contract. Ana wants to run 4 of the calls with former customers she knows personally.
Notes from Customer Success and Legal5 of the 6 at-risk accounts are in renewal talks, and Customer Success is offering them discounts. Interviewers must not discuss pricing, discounts or what's on our roadmap. Every call must start by asking permission to record.
What a strong answer doesThe answer key the graders mark against

A guide that tests both theories fairly and leaves room for a third: the goals ask what actually drove each decision to leave or doubt, when it happened, and who made it, with questions that could disprove robotics (did they automate, did robots come up before they decided, what did they switch to and why) and implementation (how long go-live took, what happened in those months, whether value arrived) alike. It treats the exit survey as weak evidence (single choice, integrations listed first, 'Other' left blank) and the 2.4× figure as a correlation to probe, not a cause. The core is a timeline of the account: the story from signing to the moment they decided to leave or started doubting, with sequential probes. It has separate tracks for the daily user (what went wrong day to day) and the signer (how the decision was made, what alternatives they weighed), fits 45 minutes with timings, and opens with consent to record. It guards the calls: no pitching, pricing, discounts or roadmap promises, with a script for when an at-risk customer asks, and it addresses Ana's bias: she has a public view and personal relationships, so she should observe or take notes rather than lead, or at minimum use the same script and have her calls read separately. It ends with decision signals: what pattern across the 12 would back Bet A, what would back Bet B, and what would back neither (price, a business change, a missing capability that isn't robotics).

Critical failures (cap the score at 40)

Output

Crate churn research: decision guide

Decision: In four weeks, allocate two squads next half to robotics integrations (A), implementation redesign (B), or conclude that neither retention thesis is sufficiently supported.

Research window: Three weeks; twelve 45-minute interviews. These calls will test explanations and reconstruct decisions—not estimate how common each churn cause is across 340 customers.

1. Learning goals

  1. Reconstruct the departure sequence: What happened between signing, implementation, first value, operational problems, searching for alternatives, and deciding to leave?
  2. Identify the decisive mechanism: Was robotics incompatibility or implementation friction necessary to the departure, merely contributory, or a justification offered afterward?
  3. Find actionable scope: Which integrations or implementation changes could plausibly have prevented the problem? Could two squads address them within a half?
  4. Look for competing explanations and counterexamples: Other missing capabilities, service failures, customer-side constraints, or business changes may explain both delays and churn.
  5. Separate operational pain from buying decisions: Did daily users and economic buyers experience the same problem and agree on why the relationship failed?

Starting evidence is suggestive, not conclusive. The survey’s broad, first-listed integration option does not establish robotics demand. The 2.4× churn association does not establish that delays caused churn. Competitor destinations do not establish purchase motives; nine lost prospects are acquisition evidence, not retention evidence.

2. Changes to the call plan

Resolve the interview arithmetic. Twelve accounts with two separate interviews each would require 24 calls. Within the limit, recruit six accounts, interviewing both roles separately: twelve calls total.

Use four churned accounts and two at-risk accounts. This prioritizes actual decisions and reduces exposure to active renewal negotiations while retaining prospective evidence.

Select accounts purposively from the eligible pool, not through executive relationships:

  • Include late and on-time go-lives, plus a failed/never-live implementation if available.
  • Include known robotics signals and accounts without them.
  • Include first-year and longer-tenure departures.
  • Seek counterexamples: late implementation without abandonment; robotics discussion without an actual deployment or switch.

Do not attempt a fully balanced matrix with six accounts. Document selection, refusals, substitutions, and gaps. Check whether the nine-month churn window excludes relevant cases from the annual churn rise; expand to twelve months if needed.

For at-risk accounts, prioritize the one outside renewal talks. CS must confirm that participation—or refusal—will not affect commercial treatment. If a renewal makes independent research impractical, substitute another eligible account.

Ana should not lead interviews with former customers she knows. Use a neutral researcher or PM who owns neither bet. Ana can help recruit through a standard invitation and review consented recordings afterward. Avoid executive attendance that could suppress criticism.

Before calls, prepare a factual account timeline from CRM, implementation logs, support records, and available usage data. Keep interpretations separate. Examine cohort definitions and potential confounders behind the 2.4× figure.

3. Interview guides

Both guides total 45 minutes. Ask open questions first; introduce the two hypotheses only after the participant’s unaided account.

Guide A: Warehouse operations manager

TimeQuestions
0–4 minFirst words, before recording: “May we record this conversation for internal research? Saying no is completely fine; we can take notes instead.” Wait for permission before starting recording. Explain that this is research, not a sales or renewal conversation; participation is optional. “What did you personally own, and during which period?”
4–10 min“What was happening in the warehouse when you chose Crate? What job did you expect it to improve? How would you have recognized success?”
10–20 min“Walk me through signing to the first real production use.” Probe planned versus actual milestones, dependencies, workarounds, ownership, and first useful outcome. “Tell me about a specific day when progress stalled. What happened next?” If never live, trace the last completed milestone and stopping point.
20–30 minChurned: “When did you first think Crate might not work for you? Describe the incident. What happened between that and leaving?” At-risk: “How is Crate working today? Describe the most recent serious problem. Has anyone discussed changing systems? What has actually happened so far?” For both: “What did this cost operationally—time, throughput, errors, or customer commitments? Who saw it?”
30–39 min“What changes in equipment or workflow occurred during this period?” Then probe robotics neutrally: “Were robots evaluated or deployed? Which systems, for what workflow, and when? What specifically could Crate not do? What workaround did you try?” Separately: “Once implementation ended—or stalled—what problems remained?” Do not assume either issue existed.
39–45 min“Which issue mattered most, and what makes you say that? If only that issue had been resolved then, what would still have made Crate unsuitable?” Ask for optional, redacted supporting artifacts and names of decision participants. Summarize the timeline and invite corrections: “What important explanation have I missed?”

Guide B: VP Operations or COO

TimeQuestions
0–4 minUse the same recording-permission opening and research boundaries. “What was your role in selection, implementation oversight, and the decision to stay or leave?”
4–10 min“What business outcome justified choosing Crate? What deadline or event made that outcome important? What expectations were set?”
10–22 minChurned: “Walk me from the first concern to the decision to leave. When was that decision effectively made, rather than formally communicated? Who influenced it? What alternatives did you evaluate?” At-risk: “How are you evaluating whether Crate is working? Has a change been proposed or authorized? What evidence and next steps are involved?” Separate firsthand knowledge from reports by others.
22–31 min“What specific event most changed your confidence? What did you do afterward? What attempts were made to recover the relationship?” Churned: “What did you choose instead, and what requirement made it preferable? Is it operating successfully yet?” At-risk: “What requirements would any alternative have to meet?”
31–39 minTest both explanations, varying their order between interviews. “What role, if any, did implementation timing play? When did it affect your judgment?” “What role, if any, did warehouse automation play? Was there an approved project, named equipment, deployment date, or demonstrated integration requirement?” “Which problems would have remained if each had been solved?”
39–45 min“What would Crate have needed to change, by what date, to alter your decision?” Treat this counterfactual as weaker evidence than actions already taken. “What evidence might contradict your explanation?” Request optional artifacts, recap, and invite corrections.

4. Interviewer operating rules

  • Be curious, not persuasive. Do not quote Ana, Marcus, survey percentages, or the churn correlation.
  • Probe concrete events: “When?” “Who?” “What happened next?” “How do you know?” Distinguish recollection, inference, and observed action.
  • Do not discuss pricing, discounts, or roadmap commitments. If raised: “I can’t discuss commercial terms or future plans here; your account team can handle those separately.” Do not promise escalation outcomes.
  • Interview roles separately; do not reveal the other person’s answers. Disagreement is evidence to investigate, not average away.
  • Use a neutral note-taker. After each call, record chronology, spontaneous versus prompted reasons, supporting evidence, contradictions, and confidence.

5. Evidence required for the decision

Back A if multiple independent accounts—including actual departures—show committed robotics adoption, a specific blocking Crate incompatibility before the departure decision, failed workarounds, and credible evidence that resolving it would have preserved the relationship. Shared, feasible integration needs must emerge. Generic “missing features,” aspirational automation, or competitor capabilities alone do not qualify.

Back B if multiple accounts—including actual departures—show preventable implementation failures preceding loss of confidence, concrete operational consequences, and a credible path from faster successful activation to retention. Identify repeatable Crate-owned bottlenecks. Delays driven mainly by customer readiness, complexity, or already-failing relationships weaken this case.

Back neither if accounts remain contradictory, both theories depend on hypothetical claims, another mechanism dominates, or neither intervention fits the capacity and time available. If both qualify, compare affected retention exposure, intervention feasibility, and remaining uncertainty—not interview vote totals.

Run two pilot calls in week one, finish most interviews in week two, and reserve week three for remaining calls and synthesis. Produce one evidence sheet per account; paired interviews count as one account, not two confirmations. The final readout should combine those cases with cohort data, explicitly separate causality from correlation, and state what remains unproven before recommending either allocation.

Churn Discovery Calls: Discussion Guide

For: exec team (read before calls start), interviewers, note-takers Timeline: week 0 for data pull and recruiting, weeks 1–3 for calls, week 4 for synthesis and recommendation

Why we're doing this

Both bets rest on a theory we haven't tested. The data we have can't settle it:

  • The exit survey doesn't separate the theories. "Missing features or integrations" (46%) was listed first, it was a single choice, and it combines robotics with every other feature gap. The free-text box was almost always left blank.
  • The robotics evidence is thin for churn. 3 churned customers moved to a competitor with robotics integrations. That is 3 of roughly 60 churned accounts. The 9 lost new-logo deals are about acquisition, not churn.
  • The implementation evidence is a correlation. Customers who went live after 90 days churned at 2.4× the rate. But complex customers may both take longer to go live and churn more for other reasons.
  • We don't know when or why the leave decision formed. That is the question the calls exist to answer.

Twelve calls can show us how customers decide to leave. They can't show us how many leave for each reason. The CRM pull below fills that gap, and the calls and the data should be read together.

1. Learning goals

  1. When did the leave decision form, and what triggered it? In the first months or later? During implementation, after go-live, or around an automation project?
  2. Does implementation delay cause churn, or just come with it? If delay mattered, was the cause on our side (fixable by Bet B) or on theirs (data readiness, their staffing)?
  3. Is automation a real driver? Are customers actually automating? Did Crate's lack of robot integration block them, or did it come up afterwards as a reason?
  4. Do signers and daily users tell the same story? Executives may cite strategy (automation). Operations managers may cite experience (implementation, usability).
  5. Are the reasons something else entirely? For example: price, support, acquisition, consolidation, or a non-robotics feature gap.

2. Changes to the plan

1. Pull CRM data in week 0, before the first call. For every account that churned in the last 12 months, pull: - tenure at churn - days from signing to go-live - whether they run or were deploying automation (ask CS and account managers) - where they went

Also answer one question: did the rise from 11% to 18% churn come from first-year customers? If it did, that supports Bet B. If the increase is among long-tenured accounts, that points toward Bet A. This may be the most decisive single fact we get, and it costs a day.

2. Replace at-risk accounts that are in renewal talks. Five of the six are negotiating discounts. They have a reason to exaggerate complaints, and a call with them could easily drift into pricing. Use red-health accounts that are not in active renewal. If there aren't enough of those, add churned accounts instead.

3. Fix the call count. The plan says 12 calls, but two people on each of 12 accounts is 24 calls. Within the 12, I propose 8 accounts:

GroupAccountsWho we interviewCalls
Churned, paired4Signer and ops manager, separately8
Churned, signer only2Signer2
At-risk, not in renewal2Signer2
  • Split the churned accounts so that 3 left in their first year and 3 left later.
  • Include at least one account that moved to a competitor with robotics integrations.
  • Signers get priority because they made the decision.
  • The paired accounts let us compare what the signer says with what the daily user saw.
  • If we can fund 24 calls, pair every account.

4. Ana should not interview her own contacts. Anyone will soften or reshape their story when the CEO asks, especially a CEO they know and whose view they may already have heard. Her contacts also aren't a random sample of the people who left.

My suggestion: - Her contacts can enter the pool if they fit the sampling groups, but a neutral interviewer runs those calls. - Ana and Marcus both listen to the recordings. - If Ana wants to speak with former customers personally, those calls are valuable for the relationship. We run them in addition to the 12 and don't count them as research.

The same rule applies to Marcus: neither exec interviews.

5. Offer a thank-you gift to former customers, such as a gift card. It must not be a credit or discount on Crate.

3. Discussion guide: VP Ops / COO (signer), 45 minutes

0–3 min · Opening - Ask permission to record. If they say no, don't record and take notes only. - Say: "This isn't a sales call. I can't discuss pricing or our product plans. I'm here to understand your experience, good and bad."

3–8 min · Context - "Tell me about your business and how it's changed over the last two years." - "What were your biggest operational priorities this past year?"

8–22 min · The decision story (the core of the call) - Churned: "Take me back to the first moment you started to wonder whether Crate was right for you. What was going on?" - At-risk: "Tell me about the last time you seriously questioned renewing." - Build a timeline with follow-ups: - "When was that, relative to signing?" - "What happened next?" - "Who else was involved?" - "What alternatives did you look at?" - "When was the decision final?" - "What finally tipped it?"

22–30 min · Expectations and early months - "When you signed, what did you expect Crate to do for you, and by when?" - "How did going live compare to what you expected?" - "When, if ever, did you first see the value you signed up for?"

30–37 min · Operational direction - "What investments in the warehouse have you made or planned: equipment, systems, staffing?" - "What did you need your WMS to do as part of those?" - If they mention automation: "How did Crate fit, or not? What did you do about it?"

37–42 min · Prompted check - Hand over a card of possible reasons: implementation time, robotics/automation integration, other missing features, ease of use, support, price, business change. - Rotate the order on every call. The survey showed the first option gets picked more. - Ask: "Pick the top three for you." Then: "Which one, if it had been different, would have changed the outcome?"

42–45 min · Close - "What should I have asked?" - "Who else should we talk to?" - Thank them.

4. Discussion guide: Warehouse operations manager, 45 minutes

0–3 min · Opening - Same as the signer call: recording permission and ground rules.

3–10 min · Daily work - "Walk me through a typical day using Crate." - "What other tools or spreadsheets did you use alongside it?"

10–22 min · Implementation story - "Tell me what happened from signing to go-live." - "What took longest?" - "What were you waiting on, and who was it waiting on?" - "When did it start working the way you needed?" - Get specific episodes, not a verdict. Always ask whether a delay came from us, from them, or from a third party.

22–32 min · Gaps and workarounds - "Tell me about the last time Crate got in your way." - "What equipment or automation runs on your floor? How does information move between it and Crate?" - "What manual steps did that create?"

32–37 min · The decision - "Were you part of the decision to leave or renew? What would you have told leadership?"

37–42 min · Prompted check - Same card as the signer call, with a new random order.

42–45 min · Close - Same as the signer call.

5. Guidance for interviewers

Stay neutral - Don't say "robotics," "automation," or "implementation" before the prompted check, unless the interviewee says it first. What people raise unprompted is our strongest evidence. - Ask about specific past events ("the last time…", "walk me through…"), not opinions or hypotheticals. Treat "we'd have stayed if you'd had X" as weak evidence. - Use their words, not ours. Don't correct them or defend Crate. - In paired accounts, use different interviewers where possible. Never tell the second person what the first one said.

Stay within the rules from Legal and CS - Pricing or discounts: "That's outside what I can cover today. I'll let your account team know you'd like to discuss it." Then tell CS. - Roadmap: "I can't speak to product plans, but I'll make sure what you've said reaches the people who make them." Never promise a feature. - If there's no recording consent, don't record. The note-taker writes verbatim quotes where possible.

Process - A note-taker joins every call. - Within 24 hours, fill in the debrief template: - primary reason, in their words - the decision timeline, with the month the doubt started - robotics raised unprompted? (Y/N) - implementation raised unprompted? (Y/N) - was the delay caused by us, them, or both? - top three from the card - the best quote - Hold a 30-minute team review of the debriefs every Friday.

6. What would back each bet

Each account gets classified by its primary cause, meaning the thing that started or tipped the decision. When signer and ops manager disagree, record both views; don't average them.

Back Bet A (robotics) if: - In at least 3 of the 6 churned accounts, automation was raised unprompted and came before the leave decision. - The customer had a live or funded automation project that Crate blocked or made harder. - Ops managers describe concrete workarounds between robots and Crate. - The CRM pull shows churn concentrated in longer-tenured accounts, with meaningfully more automating churners than the 3 we already know about. - Warning sign: robotics only comes up at the card, or appears in the timeline after the decision was already made. That suggests it's a justification, not a cause.

Back Bet B (implementation) if: - In at least 3 of the 6 churned accounts, doubt formed during or soon after a slow implementation, often phrased as "never saw the value" or "lost confidence." - Ops managers put the main delays on our side: our process, staffing, data migration, or configuration. Those are what a rebuild would fix. - The CRM pull shows the rise in churn comes mostly from first-year customers. - Warning sign: delays were mostly on the customer's side (their data wasn't ready, they didn't have staff). A faster process on our end would then help less than the 2.4× figure suggests.

Back neither if: - Primary causes are spread across several reasons with no clear lead, such as price, support, consolidation or acquisition, or a feature gap unrelated to robotics. - Or signers and ops managers consistently tell different stories that neither bet addresses.

In that case, I'd recommend a smaller fix aimed at whichever cause leads, plus a better-designed exit survey, rather than committing two squads on a weak signal.

If both show up: check whether automating customers are also the ones with the slowest implementations. If they are, those customers' problem is really integration work during setup, and the recommendation should address that directly instead of forcing a choice between A and B.

In week 4, I'll bring the exec team a one-page summary that combines the call findings with the CRM figures, a recommendation, and our confidence in it.

Crate customer research guide: why are warehouses leaving?

Purpose: In three weeks, learn whether churn is more plausibly driven by missing robotics integrations (Bet A), slow implementation (Bet B), or something else. These calls are for understanding customers’ experiences—not selling, negotiating renewals, or validating either executive’s theory.

Learning goals

For each account, establish:

  • What happened, and when? Separate implementation, go-live, first value, automation needs, and the point when leaving became likely or decided.
  • What mattered most? Distinguish a decisive problem from a feature request, contributing frustration, or reason offered after the fact.
  • What evidence supports the explanation? Look for actual workflow impact, workarounds, alternatives evaluated, and actions taken—not just opinions or hypotheticals.
  • What might change the outcome? Explore credible counterfactuals without promising anything.
  • What else explains churn? Surface causes beyond A and B.

Recommended plan changes

The proposed 12 calls cannot cover both the daily user and contract signer on all 12 accounts: that would require 24 interviews. Keep the 12-call cap, but interview two roles separately at each of six accounts: three churned accounts and three red-health accounts, with one warehouse operations manager and one VP of Operations/COO per account. This gives paired perspectives and preserves both customer situations, but is a small, directional sample—not a prevalence estimate. Select accounts for varied implementation times and automation situations where possible; don’t choose only accounts with known robotics issues.

Do not have Ana conduct four calls with former customers she knows personally. Her involvement risks courtesy bias and leading the conversation. Use an independent interviewer; ideally don’t include personal contacts in this small core sample. If one is included, disclose the relationship, and have Ana neither attend nor receive attributable notes.

Because five at-risk accounts are in renewal talks and receiving discount offers, use an interviewer outside the account/renewal team. Tell participants their answers won’t affect service or renewal discussions. Don’t share interview content with the account team in a way that could be used in negotiation. Follow Legal’s recording requirement below.

45-minute guide: churned customers

TimeQuestions
0–3Start by asking: “May I record this conversation?” If no, take notes instead. Explain the purpose, that there are no sales or renewal implications, and that we won’t discuss pricing, discounts, or roadmap.
3–7“What was your role in choosing and using Crate?” “What did your warehouse need the system to help you do?”
7–18“Take me through your experience with Crate, from signing through the decision to leave.” “When did you first consider switching? What happened just before that?” “Who was involved, and when was the decision effectively made?”
18–27“How did implementation and go-live go?” “Where, if anywhere, did it take longer or require more effort than expected?” “What was the impact on your operation?” “When did you first get value from Crate?”
27–35“Did automation or robotics play a role in your warehouse during this period?” If yes: “What equipment or workflow?” “How did it work with Crate?” “What did you do when it didn’t?” “When did this become a problem relative to the decision to leave?”
35–41“What alternatives did you consider, and what drove the choice?” “What, if anything, could realistically have changed your decision?” “What was the most important reason—not just one frustration?”
41–45“What haven’t I asked that matters?” “Is there anything we should correct about our understanding?” Thank them.

27–35“How, if at all, does automation or robotics fit into your operation?” If relevant: “What equipment or workflow?” “How does it work with Crate today?” “What workarounds do you use?” “When did this become important?”
35–41“Have you considered alternatives to Crate? What prompted that, if so?” “What would need to be true for Crate to work well for your operation?” “What are the most important unresolved issues?”
41–45“What haven’t I asked that matters?” “Is there anything we should correct?” Thank them.

Guidance for interviewers

  • Ask the questions as written, but follow the participant’s timeline. Use neutral probes: “What happened next?” “Can you give me an example?” “How do you know?”
  • Don’t offer Ana’s or Marcus’s theories, mention the exit-survey results, or ask leading questions such as “Would robots have saved you?” Ask about events before asking for interpretations.
  • Separate when an issue occurred from when the participant says it mattered. Probe for specific actions and evidence: evaluations, workarounds, escalations, or a switch decision.
  • Don’t discuss pricing, discounts, renewal negotiations, or roadmap. If asked about roadmap, say you can’t speak to future plans. Don’t make promises or relay an interview answer as a renewal signal.
  • Interview roles separately. Record role and account context in notes, but distinguish direct experience from second-hand views. Afterward, write a short timeline, leading cause(s), evidence, and uncertainties for each account.
  • Treat recordings and notes as confidential; use only with consent and Legal-approved handling. Don’t present anecdotes as representative of all customers.

What would support each bet?

Support Bet A (robotics integrations): In multiple independent accounts, a specific robotics workflow or integration gap caused meaningful operational friction, and that issue arose before the decision to leave or seriously consider leaving. Stronger evidence: an actual robot deployment or concrete plan, a costly workaround, and a competitor selected or evaluated for this capability. A feature mention alone—or robotics cited in a new-logo deal—doesn’t establish that it drove existing-customer churn.

Support Bet B (faster implementation): In multiple accounts, implementation delays or effort materially postponed go-live or first value, caused operational consequences, and preceded the decision to leave or consider leaving. Stronger evidence: specific preventable blockers, an unmet expectation, and a credible account that earlier go-live would have changed the outcome. The 94-day median, 45-day promise, and 2.4× association make this worth testing, but do not prove causation.

Support neither / remain uncertain: The call evidence points more strongly to another cause; A or B appears only after the decision; accounts describe issues without meaningful consequences; or evidence is mixed and no cause consistently precedes churn. Don’t force a winner from 12 interviews. Compare patterns across accounts, not individual interview counts, and triangulate with CRM timelines and other churn evidence. The exit survey’s single-choice format, first-listed feature option, and sparse free text limit what it can establish.

Where they differ 6

Uses the supplied evidence correctlyMixedWrongRight
GPT-6 Astra · ChatGPT

It invents current data sources by saying to prepare timelines from support records and usage data, which are not supplied.

Opus 5.5 · Claude

It invents or overstates a few current-situation facts, including 'roughly 60 churned accounts' and 'the survey showed the first option gets picked more'.

GPT-6 Luna · API

Every statement about the current situation is taken directly from the supplied context, with no invented facts.

Addresses the actual decisionMixedRightRight
GPT-6 Astra · ChatGPT

It does not commit to one answer early; it only states the decision frame and later gives evidence thresholds, leaving the exec team without a clear recommendation.

Opus 5.5 · Claude

It gives the exec team a clear decision rule for Bet A, Bet B, or neither, with thresholds and warning signs.

GPT-6 Luna · API

The guide clearly states what evidence from the calls would back Bet A, Bet B, or neither, which is the decision framework the exec team needs.

Respects explicit constraintsMixedWrongRight
GPT-6 Astra · ChatGPT

It respects the no-pricing/roadmap and consent constraints, but it does not mark must-ask questions or say what to cut if time runs short, and it introduces unsupported data sources.

Opus 5.5 · Claude

It exceeds the 1,500-word limit and proposes replacing the at-risk cohort in a way that changes the supplied plan beyond the brief's constraints.

GPT-6 Luna · API

The guide respects all constraints: it includes learning goals, timed questions for both customer types, interviewer guidance, plan changes, and decision signals; it stays under 1,500 words; it enforces no pricing/roadmap discussion and recording consent.

Avoids unsupported claimsRightMixedRight
GPT-6 Astra · ChatGPT

It labels exec theories and survey/correlation evidence as suggestive rather than established, though it still has a minor unsupported data-source claim.

Opus 5.5 · Claude

It presents the first-option bias and the 'roughly 60 churned accounts' figure as established facts when the supplied evidence does not support them.

GPT-6 Luna · API

Interpretations like the exit survey's limitations and the 2.4× association are clearly labeled as not proving causation, not presented as established fact.

Produces the required deliverableRightMixedRight
GPT-6 Astra · ChatGPT

It provides learning goals, timed two-role questions, interviewer guidance, plan changes, and decision signals within the length, and the exec team could act on it with light edits.

Opus 5.5 · Claude

The guide is complete and usable, but it is over the requested length.

GPT-6 Luna · API

The output is a complete call guide with all requested sections, written for the exec team, and well under 1,500 words.

Different questions for user and signerRightRightWrong
GPT-6 Astra · ChatGPT

It has separate timed tracks for the daily warehouse operations manager and the VP/COO signer, matched to operational experience versus decision process.

Opus 5.5 · Claude

It provides distinct 45-minute tracks for the signer and the daily operations manager.

GPT-6 Luna · API

The guide does not provide distinct question tracks for the daily warehouse operations manager and the executive who signed; it only differentiates churned vs at-risk customers, with the same questions for both roles within each track.

All got wrong 1

Marks what to cut if the call runs overWrongWrongWrong
GPT-6 Astra · ChatGPT

Timings add to 45 minutes, but the guide does not mark must-ask questions or specify what to cut if time runs short.

Opus 5.5 · Claude

It provides timings but does not mark must-ask questions or say what to cut if the call runs over.

GPT-6 Luna · API

Although timed sections add up to 45 minutes, the guide does not mark must-ask questions or say what to cut if time runs short, so an interviewer could run out of time without covering the most critical probes.

All got right 6

Identifies material uncertaintyRightRightRight
GPT-6 Astra · ChatGPT

It names key unknowns such as survey bias, correlation versus causation, timing of churn decisions, confounders, and renewal exposure, and says how calls and data checks would resolve them.

Opus 5.5 · Claude

It names the key unknowns—timing of the leave decision, whether delay causes churn, and whether automation is a real driver—and says how calls and CRM pulls would resolve them.

GPT-6 Luna · API

It names key unknowns (exit survey weakness, correlation vs causation, timing of churn decision) and says how the calls will resolve them through patterns and timelines.

Tests both theories fairlyRightRightRight
GPT-6 Astra · ChatGPT

It asks open timeline questions before introducing either theory and gives both robotics and implementation questions that could disprove each, while leaving room for third causes.

Opus 5.5 · Claude

It gives both robotics and implementation equal chances to be disproved and leaves room for a third cause.

GPT-6 Luna · API

Both the robotics and implementation theories get questions that could disprove them, open timeline questions come first, and the guide explicitly leaves room for a third cause.

Protects the calls and the accountsRightRightRight
GPT-6 Astra · ChatGPT

It starts with recording consent, bans pricing/discounts/roadmap, gives a script if raised, and concretely removes Ana from leading calls with people she knows.

Opus 5.5 · Claude

It includes recording consent, scripts for pricing/roadmap, and a concrete plan to keep Ana from leading calls with her contacts.

GPT-6 Luna · API

It gives a clear rule and script for pricing/roadmap questions, starts with recording consent, and addresses Ana's bias by recommending she not lead calls and, if a contact is included, that she not attend or receive attributable notes.

Designed to falsifyRightRightRight
GPT-6 Astra · ChatGPT

Each learning goal has disconfirming probes, including counterexamples, timing of decisions, failed workarounds, and questions about what would still have caused churn.

Opus 5.5 · Claude

Each learning goal has questions that could falsify the corresponding hypothesis, such as timing, cause of delay, and unprompted automation mentions.

GPT-6 Luna · API

Every learning goal has questions whose honest answers could disprove the hypothesis, such as asking when automation became a problem relative to the decision to leave.

Asks what people did, not what they thinkRightRightRight
GPT-6 Astra · ChatGPT

The core questions ask for specific events, timelines, actions, alternatives evaluated, and what happened next, with hypotheticals clearly secondary.

Opus 5.5 · Claude

The core questions ask for specific past events, timelines, and actions rather than opinions or hypotheticals.

GPT-6 Luna · API

Core questions ask for specific past events and actions (e.g., 'When did you first consider switching? What happened just before that?'), with opinions and predictions clearly secondary.

Doesn't lead the witnessRightRightRight
GPT-6 Astra · ChatGPT

Questions are open and neutral, hypotheses are introduced only after unaided accounts, and the guide does not pitch either bet or ask customers to choose.

Opus 5.5 · Claude

It explicitly avoids naming robotics or implementation before the prompted check and uses neutral, open questions.

GPT-6 Luna · API

Questions are neutral and open; the guide avoids mentioning either executive's theory until after the participant's own timeline, and prohibits leading probes.
