How it’s graded

Each check is built on how world-class product and growth leaders do this work, as they’ve described it on Lenny’s Podcast, and names the leader it comes from.

  1. Designed to falsify

    For each learning goal, does the guide include a question whose honest answer could show the team's hypothesis is wrong?

    Passes when Every learning goal has at least one disconfirming, non-leading question, such as asking about the last time they had the problem and what they did instead.

  2. Asks what people did, not what they think

    Are the core questions about specific things the person actually did recently, rather than opinions, predictions or hypotheticals?

    Passes when The core of the guide asks for recent, specific instances (the last time, what happened, what they did) and follows up on them; opinions and predictions are absent or clearly secondary.

  3. Doesn't lead the witness

    Are the questions free of leading wording, of pitching the idea, and of hints at the answer the team hopes for?

    Passes when Questions are neutral and open, and the idea is not described (or only at the very end, after the problem questions).

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)
  • Includes questions that promise roadmap items or discuss pricing or discounts with customers in renewal talks
  • Asks customers to choose between robotics and implementation as the reason they left

Output

Customer Interview Guide: Why Are Customers Leaving?

Owner: Staff PM | Calls: 12 × 45 min, over three weeks | Readout: before the exec decision in four weeks

1. Learning goals

  1. Timing: When did the customer first consider leaving, and what was happening then (signing, go-live, first 90 days, renewal)? This tells us whether churn is decided early or late.
  2. Reasons, in their order: What were the reasons for leaving or staying, ranked in the customer's own words, before we prompt anything?
  3. Automation: Are they automating their floor, which systems do they need Crate to connect to, and was that gap a blocker or a workaround?
  4. Implementation: Where did time go between signing and daily use, and who was waiting on whom?
  5. Alternatives: What did they evaluate instead, and what did that option do better?

2. Changes to the plan (please read before the calls start)

  1. Ana should not run calls with accounts she knows. Personal relationships make candid criticism less likely, and Ana is the sponsor of Bet A. She can provide introductions and read the notes afterward. Neutral interviewers run those four calls on accounts she doesn't manage.
  2. The plan implies 24 conversations, not 12. Each account has two contacts. I propose 12 × 45-minute calls with the operations manager on every account, plus a 20-minute executive call (VP/COO) on as many accounts as we can reach, aiming for six.
  3. Rebalance the sample. Churned accounts are 9 of the 12 calls, and the at-risk sample is weighted toward accounts in renewal talks (see point 4). Within the churned group, make sure we have at least three go-lives over 90 days and three under 90, and at least three accounts running automation and three that aren't. Without this spread, we can't tell robotics from implementation.
  4. Renewal talks distort at-risk answers. Five of six at-risk accounts are negotiating renewals with discounts on the table. Customers will say what helps their negotiation, and we can't fully control for that. Treat at-risk answers as evidence of current pain, not reasons for churn. If possible, swap two at-risk accounts for churned accounts from months 9–12 of the exit survey window.
  5. Pull data this week, not after the calls. Get churn-notice dates, go-live dates, and integration usage for all 41 churned accounts. This lets us test the timing question quantitatively.
  6. Don't treat the exit survey as proof. Missing features was the first option, the "Other" box was almost empty, and the question forced one answer. The 46% doesn't tell us it's robotics. Use these calls to check it.
  7. Agree the decision thresholds now (section 5), before we hear anything.

3. Questions and timings

Opening (3 min), verbatim: > "Before we start, may I record this? It's for internal research only, and I'll share unattributed summaries. You can stop at any point. We're not selling anything today, and I can't discuss pricing, offers, or product plans. I want to understand what happened for you."

A. Context (5 min) - Walk me through your warehouse operation and your role in it. - What does Crate do for you day to day, or what did it do before you stopped using it?

B. The timeline (12 min) Most important block. Get dates. - Walk me through the last time you were seriously considering leaving [or: seriously worried about the relationship]. When did that start? - What was happening at that point? Who was involved? - When did it become a real decision? What triggered it? - Probe for dates: "Roughly which month was that? What was going on at go-live?"

C. Reasons, unprompted (8 min) Don't mention robotics yet. - Looking back, what were all the reasons, in order of importance? - What made the difference between staying and leaving? - If we'd fixed one thing, would you have stayed? - What did you look at instead? What did it do that we didn't?

D. Automation (7 min) Only after block C. - What has changed on your floor over the past two years? Any carts, pick-assist robots, or other automation? - Which systems does Crate need to connect with? How did your team work around the gap? - Was that a blocker, or a nice-to-have? - Did anyone raise it in a renewal or evaluation discussion?

E. Implementation (8 min) - How long did it take from signing to your team using Crate daily? - Where did the time go? Who was waiting on whom? - When did your team first feel it was working?

F. Close (5 min) - If you were us, what would you fix first? - Is there anything I should have asked?

Executive variant (20 min): Spend the time on blocks A, B, and C, plus: how the decision was made and who approved it; what they evaluated; how automation fits into their operating plan for the next 12 months; and what they told their team about Crate.

At-risk variant: Replace "what made the difference between staying and leaving?" with "what's working well today and what's getting in the way?" Do not ask about renewal, pricing, or whether they plan to stay.

4. Guidance for interviewers

  • Two people per call: one leads, one takes notes. No one from Sales or Customer Success on the call.
  • Don't name robotics, the 46% figure, or our hypotheses. Don't ask leading questions ("Isn't it frustrating that…?").
  • Ask about specific past events, not hypotheticals ("Would you use…?"). Ask "What else?" until they run out.
  • Let silence work. Don't fill it.
  • Don't promise anything. If asked about features or fixes: "I'll pass that on, but I can't say what we'll build."
  • Pricing or discounts: Don't engage. Say "I can't discuss that today. I'll make sure your account team knows you raised it." Record their words verbatim and tell Customer Success after the call. CS owns the follow-up.
  • Debrief within two hours. Fill in one template: go-live and churn dates, reasons in the customer's order, whether robotics came up unprompted or after a prompt, implementation duration, and up to three verbatim quotes.

5. What we'd need to hear

Thresholds are directional. Twelve calls can't prove anything, but they can show whether a theory holds up.

Back Bet A (robotics integrations) if: - At least 5 of 12 name a specific automation system that Crate can't connect to as a primary reason for leaving or evaluating alternatives. This should come up in block C or D, not only after prompting. - At least 3 say the integration would have changed the outcome. - The decision to leave happened late in the contract, not during implementation. - Churned accounts that ran automation churned for reasons that match the exit survey.

Back Bet B (faster implementation) if: - At least 5 of 12 say the decision started during go-live or in the first 90 days. - They name specific bottlenecks: data migration, configuration, waiting on our team, or connecting to their existing systems. - At least 3 say faster go-live would have kept them. - In the pulled data, go-live time separates churned accounts from retained ones more sharply than automation does.

Back neither if: - Reasons are spread across price, service, reporting, or other issues, with no dominant theme. - Robotics comes up, but few customers have automation projects planned in the next 12 months. - Implementation was slow, but the decision to leave was made at renewal for unrelated reasons. - The real driver is weak executive sponsorship or a lack of internal champions, which neither bet addresses.

If neither bet is backed, the readout should say so directly and name the pattern that did emerge. Don't force a choice between A and B if the evidence points elsewhere. If the evidence supports both, the readout should say which has stronger support and what would change that conclusion.

Claims the judge couldn’t find in the brief

A PM could use most of it after light edits, but the unsupported data-source claim and missing must-ask/cut guidance require re-checking and revision before running the calls.

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.

Needs more than a quick edit11 of 13 checks passed

The guide lacks separate question tracks for the daily user and the decision-maker, and it doesn't prioritize questions for time management. A PM would need to add role-specific questions and mark must-asks, which is more than a quick edit.

Output

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.

45-minute guide: red-health customers

Use the same opening and close. Do not imply that Crate can fix an issue or influence renewal terms.

TimeQuestions
0–3Start by asking: “May I record this conversation?” If no, take notes. Explain that this is research, not a sales or renewal conversation; participation won’t affect service or renewal discussions.
3–7“What is your role in using or overseeing Crate?” “What does a successful warehouse operation look like for you?”
7–17“How has your experience with Crate unfolded so far?” “When have things gone better or worse than expected?” “What is working well today?”
17–27“Where are you in implementation and go-live?” “What has taken the most effort or time?” “What value, if any, have you realized so far?” “What is the operational impact of anything that remains difficult?”
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.

Check by check

Where the outputs differ comes first. Open a check to read the judge’s reasons. “Mixed” means the two graders disagreed.

Where they differ 5

Uses the supplied evidence correctlyMixedMixedRight
Haiku 5.5 · API

The claim 'Customers will say what helps their negotiation' is an unsupported behavioural statement not derived from the context.

GPT-6 Astra · ChatGPT

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

GPT-6 Luna · API

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

Addresses the actual decisionRightMixedRight
Haiku 5.5 · API

Section 5 clearly lays out what patterns would back Bet A, Bet B, or neither, satisfying the requirement for decision signals.

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.

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 constraintsRightMixedRight
Haiku 5.5 · API

The output is under 1,500 words, includes all requested elements, and enforces pricing/roadmap silence with a script.

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.

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 claimsMixedRightRight
Haiku 5.5 · API

The statement 'Customers will say what helps their negotiation' is presented as fact without caveat or support.

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.

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.

Different questions for user and signerRightRightWrong
Haiku 5.5 · API

Distinct tracks exist for the operations manager (main 45-min guide) and the executive (20-min variant focusing on decision process).

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.

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
Haiku 5.5 · API

The timed sections sum to 48 minutes, exceeding the 45-minute limit, and the guide does not mark what to cut if time runs short.

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.

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 7

Identifies material uncertaintyRightRightRight
Haiku 5.5 · API

It explicitly treats the exit survey as weak evidence, notes the small sample cannot prove anything, and says what to do if neither bet is backed.

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.

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.

Produces the required deliverableRightRightRight
Haiku 5.5 · API

It delivers a complete interview guide in the required form for the exec team, within the word limit.

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.

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.

Tests both theories fairlyRightRightRight
Haiku 5.5 · API

Open questions on reasons come first; automation and implementation are probed separately with neutral questions, giving both theories equal chance to fail.

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.

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
Haiku 5.5 · API

Consent is requested at the start, a script deals with pricing/roadmap inquiries, and the CEO is instructed not to run calls with accounts she knows.

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.

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
Haiku 5.5 · API

Every learning goal includes open, non-leading questions that can yield answers disproving the team's hypotheses (e.g., asking if automation was a blocker or nice-to-have).

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.

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
Haiku 5.5 · API

Core questions ask about the last time they considered leaving, what happened, and what they did, focusing on specific past events.

GPT-6 Astra · ChatGPT

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

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
Haiku 5.5 · API

Questions are neutral (e.g., 'What has changed on your floor?', 'Was that a blocker, or a nice-to-have?') and avoid pitching or hinting at desired answers.

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.

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.
