From 18 graded outputs by 9 models. 33% were usable with at most a quick edit.

Reliably right

Asks what people did, not what they think96% pass
Core questions ask for specific recent actions and events ('What happened next?', 'Who did you call?'), not opinions or predictions.
Sonnet 5.5 · API · Why are warehouses leaving? Two execs, two theories
Tests both theories fairly92% pass
Both theories get questions that could disprove them (e.g., no action on robotics, happiness after slow go-live), and open-ended timeline questions leave room for a third cause.
Sonnet 5.5 · API · Why are warehouses leaving? Two execs, two theories
Different questions for user and signer92% pass
The guide has distinct tracks: daily user questions focus on day-to-day experience and workarounds, signer questions on the decision process and alternatives.

Where it slips

Marks what to cut if the call runs over28% pass
The guide includes timed sections that add up to 45 minutes but does not say what to cut if time runs short, nor does it mark must-ask questions.
GPT-6.1 Sol · API · Why are warehouses leaving? Two execs, two theories
Doesn't trust the default reason47% pass
The plan names the pre-selected default as a bias but does not use the behaviour columns to show that most 'too expensive' cancellers had stopped cooking; it only picks two contrasting individuals without the aggregate pattern.
GPT-6 Astra · ChatGPT · Too expensive, by default

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.

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.
Judd AntinLenny’s Podcast
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.
Bob MoestaLenny’s Podcast
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 the PM for retention at Sprig. The execs each have a theory about why subscribers cancel (below). Plan next week's six churn interviews: who to recruit from the cancellation list and why, and the guide the interviewers will use, in no more than 900 words. Two of the interviewers are new to it. The files are attached.

What the model was given5 items: About Sprig, exec_hypotheses.md, cancel_form.md, cancellations_last_quarter.csv, research_constraints.md

About SprigA meal-kit subscription: recipes and ingredients delivered weekly. Subscribers can skip a week or cancel any time.

# What the execs think (for the research)

- CEO: "It's price. Competitors discount harder."
- Head of Food: "Our recipes are too repetitive after a few months."
- Head of Ops: "Late deliveries."

Retained subscribers (for comparison): 81% cooked at least 3 recipes a week in their first month; 34% of cancellers did.

# Research constraints

- Six calls, 30 minutes each, next week. The researcher can recruit from the cancellation list (consent to contact is on file for all of them).
- Two of the PMs running calls are new to interviewing.

What a strong answer doesThe answer key the graders mark against

Reads the cancellation data before trusting it: 'Too expensive' is the top reason (156 of 300), but it's the pre-selected first option, and 118 of those 156 had skipped two or more deliveries and cooked two or fewer recipes in the last four weeks: they'd stopped using the product before they left. Overall 204 of 300 skipped two or more deliveries. So the guide investigates what happened to the cooking habit, and price as one hypothesis to test rather than the answer. Recruits deliberately from the list across the patterns: people who stopped cooking and picked 'too expensive', people who kept cooking and still picked 'too expensive' (the real price cases), and people who said recipes got repetitive. The guide asks about specific recent weeks (the last box they skipped, what happened to the food, what they ate instead), each exec hypothesis has a question whose honest answer could disprove it, questions don't lead or mention price first, the guide fits 30 minutes with timings and marks what to cut, and gives the new interviewers prompts for digging deeper. Notes that the default on the cancel form should be removed.

Sprig Churn Research Plan & Interview Guide

Why Our Current Data is Misleading

Before recruiting, we must look at how our exit survey distorts reality: 1. Default Bias: "Too expensive" is pre-selected. Half our cancellers leave it checked, but their free-text responses and behavioral data tell a different story: 79% of cancellers cooked 3 or fewer recipes in their final 4 weeks, and most skipped multiple deliveries. 2. The Value-Perception Trap: When food goes uncooked ("kept piling up in the fridge", "didn't have time to cook", "too much food for two"), the effective cost-per-meal skyrockets. Subscribers aren't necessarily leaving because of sticker price or competitor discounts; they are leaving because paying for food you end up throwing away feels expensive.

Our 6 interviews will test the execs' hypotheses (Price, Recipe Fatigue, Delivery) against this underlying Utilization/Lifestyle Fit problem.

Recruitment Plan (6 Participants)

Note: Invite 2–3 backups per slot using the backup IDs provided.

1. The "Default Price" Low-Utilizer (Tests CEO Hypothesis vs. Waste) * Recruit: S-8016 (Backup: S-8029) — 14 weeks, "Too expensive (pre-selected)", skipped 4/6, cooked 0, free text: "kept piling up in the fridge". * Why: Represents our largest churn segment. Left the default reason checked, but stopped cooking entirely and threw food away. Tests if "price" actually means "wasted food."

2. The High-Usage Price Chiller (Tests True Price Sensitivity) * Recruit: S-8056 (Backup: S-8096) — 29 weeks, "Too expensive (pre-selected)", skipped 1/6, cooked 12, free text: "cheaper at the supermarket". * Why: Cooked 3 meals/week right up to cancellation (matching our retained user benchmark) with zero waste, yet still felt it was too expensive. Tests the CEO's hypothesis on a user who actually got full utility.

3. The Long-Tenure "Bored" Subscriber (Tests Head of Food Hypothesis) * Recruit: S-8057 (Backup: S-8246) — 53 weeks, "Recipes got repetitive", skipped 4/6, cooked 3, no free text. * Why: Actively changed the dropdown to "Repetitive" after a year of loyalty and recent skipping. Tests genuine menu fatigue vs. seasonal routine changes.

4. The Time-Poor "Repetitive" Subscriber (Tests Menu Fatigue vs. Cooking Effort) * Recruit: S-8022 (Backup: S-8013) — 20 weeks, "Recipes got repetitive", skipped 4/6, cooked 3, free text: "didn't have time to cook". * Why: Selected "repetitive" at 5 months, but wrote they had no time. Did the flavors get boring, or did the 45-minute prep work become a chore?

5. The "Too Much Food" Down-Sizer (Tests Plan Flexibility) * Recruit: S-8006 (Backup: S-8240) — 29 weeks, "Too expensive (pre-selected)", skipped 0/6, cooked 8, free text: "too much food for two". * Why: Consistently cooked 2 meals/week without skipping, but felt overwhelmed by volume. Tests if inflexible portion/box sizes are driving "price" churn.

6. The Early-Tenure Ops Failure (Tests Head of Ops Hypothesis) * Recruit: S-8097 (Backup: S-8152) — 2 weeks, "Delivery problems", skipped 2/6, cooked 10, no free text. * Why: High intent (cooked 10 meals in a very short window) but churned immediately citing delivery. Isolates pure operational failure during the critical first-month habit-building window.

30-Minute Interview Guide

Golden Rules for New Interviewers

Don't ask about the future or hypotheticals: Never ask "Would you have stayed if it were 20% cheaper?" (People always say yes). Ask what actually happened.
Ask for stories, not opinions: Instead of "How were the recipes?", ask "Walk me through the last box you unpacked."
Don't lead the witness: Do not mention their survey selection ("I see you cancelled because of price"). Let them bring it up.
Embrace silence: Count to 5 in your head after they finish speaking. They will often fill the silence with the real truth.

1. Intro & Warm-up (3 mins)

"Hi [Name], thanks for joining. I'm [Name] on the product team at Sprig. We're talking to former subscribers to understand how Sprig fit into your life and where it fell short. There are no right or wrong answers—criticism won't hurt my feelings, it actually helps us improve. Do you mind if I record this just for internal notes?"

2. The Origin & Early Habit (5 mins)

Goal: Understand the job they hired Sprig to do and their first-month habit.
"Take me back to when you first signed up for Sprig. What was going on in your life that made you want to try it?"
"In that first month, what did a typical week with a Sprig box look like?"

3. The Last Box (10 mins) — CRITICAL SECTION

Goal: Uncover the behavioral reality of food waste, prep time, and portion sizes.
"Think about the very last Sprig box that arrived at your door. Walk me through what happened to that box from the moment you brought it inside."
Follow-up: "How many of those meals did you end up cooking?"
If meals went uncooked: "What got in the way of cooking the others? What ended up happening to those ingredients?" (Listen for: guilt of throwing away food, fridge clutter, unexpectedly busy evenings).
"Looking back at the last month or two before you cancelled, I noticed you skipped a few weeks. How did you decide whether to get a box or skip?"

4. The Trigger & Executive Probes (9 mins)

Goal: Pinpoint the exact moment of cancellation and test exec hypotheses without leading.
"What was the exact moment you decided, 'Okay, I'm going to cancel my subscription today'?"
Use the relevant probe below based on what they bring up (or their profile):
If they mention Price / Value: "When you felt it wasn't worth the cost, how were you doing that math? Did you switch to another meal kit, or what are you doing for dinners now?"
If they mention Recipes / Food: "When you logged in to pick recipes toward the end, what was going through your head? Was it the flavors, the ingredients, or the time/effort to cook them?"
If they mention Volume / Leftovers: "How did the amount of food in the box match up with what your household actually eats?"
If they mention Delivery: "Tell me specifically what happened with the delivery. How did that impact your plans for the week?"

5. Wrap-up (3 mins)

"If a friend asked you today whether they should try Sprig, what would you tell them?"
"Is there anything else about your experience we didn't cover? Thank you so much for your time!"

Strategic Recruitment Plan

The cancellation form pre-selects "Too expensive", severely skewing quantitative data toward price. Furthermore, while 81% of retained users cook ≥3 recipes/week in month 1, only 34% of churned users do—suggesting retention is fundamentally won or lost on habit formation, pace, and food waste guilt (evident in recurring free-text notes like "kept piling up").

To evaluate exec hypotheses (Price, Recipe Repetition, Delivery) against these underlying behavioral dynamics, we will recruit six subscribers across distinct behavioral archetypes:

ID	Weeks Subscribed	Skips (Last 6 Wks)	Cooked (Last 4 Wks)	Form Reason	Free Text	Rationale & Hypothesis Tested
:---	:---	:---	:---	:---	:---	:---
S-8056	29	1	12	Too expensive	Cheaper at supermarket	CEO (Price): High cooking engagement, low skips. Tests whether high-value cooks leave for discounted competitors vs. grocery shopping.
S-8196	57	2	1	Repetitive	[None]	Head of Food (Repetition): Long tenure; actively changed radio button to "Repetitive"; cooking volume collapsed. Tests recipe fatigue threshold.
S-8072	23	1	8	Delivery problems	[None]	Head of Ops (Delivery): High cook volume; deliberately chose "Delivery problems". Tests if logistical failures break established habits.
S-8016	14	4	0	Too expensive	Kept piling up in fridge	The "Food Guilt" Trap: High skips, zero cooking. Tests if "Too expensive" is actually guilt over uneaten food and subscription velocity.
S-8006	29	0	8	Too expensive	Too much food for two	Portion/Household Mismatch: Highly engaged, zero skips, but churned. Tests unit economics and portion sizing vs. true price sensitivity.
S-8120	4	0	10	Too expensive	Cheaper at supermarket	Early Onboarding Drop-off: Active cook (10 recipes) who dropped at Week 4 discount cliff. Tests initial value proposition and promo-hopper behavior.

Backup recruits: S-8044 (Repetitive), S-8115 (Delivery), S-8038 (Price/High engagement).

Interviewer Guide (30 Minutes)

> Interviewer Note (for new PMs): > 1. Never mention their cancel form response. It was pre-selected and biases answers. > 2. Focus on stories, not opinions. Don't ask "Was it too expensive?" Ask "Walk me through the last box you unpacked." > 3. Embrace 3 seconds of silence. Let the participant fill pauses.

#### 1. Welcome & Rapport (3 mins) * "Thanks for taking the time! I’m [Name], a product manager at Sprig. We’re working to make our boxes better, and we learn the most from people who decided Sprig wasn't right for them." * "There are no right or wrong answers, and you won’t hurt my feelings. I’m recording this for notes—is that okay?"

#### 2. The Early Days & Habit Formation (7 mins) Goal: Understand the baseline expectation and initial activation (testing month-1 cooking habit). * "Think back to when you first signed up for Sprig. What was going on in your life that made you want meal kits?" * "Walk me through your first couple of weeks. How often were you cooking the meals?" * "Did you cook with someone else? How did the portion sizes fit your household?"

#### 3. The Turning Point & Kitchen Reality (12 mins) Goal: Neutral deep dive to evaluate price, delivery, repetition, and food waste without leading. * "Think about the last box you received before canceling. Walk me through what happened from the moment it arrived to when you decided to cancel." * If Ops signal: "Did it arrive when and how you expected? How did that affect your week?" * If Food signal: "How did picking your meals feel toward the end compared to the beginning? Did you feel excited by the menu?" * If Fridge/Time signal: "Did you ever have ingredients left over when the next box arrived? How did you handle that?" * "I noticed you skipped a few deliveries [or never skipped]. How did skipping fit into your routine?" * "Tell me about the specific moment you went to the website to hit 'Cancel'. What tipped you over the edge that day?"

#### 4. The Alternative & True Cost (5 mins) Goal: Test CEO hypothesis (competitors vs. grocery vs. takeout). * "Now that you aren't using Sprig, what are you doing for dinner on busy weeknights?" * "Did you try or consider any other meal kits or services? Why or why not?" * "When you think about the total cost of Sprig, what felt like the biggest driver of whether it was 'worth it'?"

#### 5. Wrap-Up (3 mins) * "If you had a magic wand and could change one thing about Sprig so that it fit your life perfectly, what would it be?" * "Thank you so much for your candor. We’ll send your $30 gift card within 24 hours."

Post-Interview Debrief Checklist (Immediately after call)

Capture within 10 minutes in Slack/Notion: 1. Primary root cause: (e.g., Recipe boredom, Food waste guilt, Box delivery timing, Absolute price, Household mismatch). 2. True competitor: (e.g., Trader Joe’s, HelloFresh, Takeout, Cooking from pantry). 3. Exec hypothesis validation: Did this support CEO, Food, or Ops? (Yes/No/Partial + 1-sentence quote).

Claims the judge couldn’t find in the brief

S-8120 cooked 10 recipes in 4 weeks and dropped at Week 4 discount cliff.
