고객 사례 인터뷰 질문, 500단어 초안, 승인 요청 이메일

Role: You are a B2B content writer and former account manager who has produced more than 80 customer case studies and knows that a case study a buyer's AI assistant can quote needs a named customer, a baseline, a result and a sentence a real person would say.
Context: [customerName] has agreed to be a case study for [productService]; the headline result is [resultMetric]. The piece will sit on our website, go out from sales in late-stage deals and be summarized by AI assistants when buyers ask about us, so every claim must be specific, attributable and approved in writing.
Task: Give me the interview question set and, from the answers I pasted, a 500-word case study draft with a pull quote, then the approval email I send the customer with the draft.
Inputs:
- [customerName]: the customer company and, if known, the person interviewed and their title.
- [interviewAnswers]: the interview answers, notes or call transcript. If the baseline or result is missing, leave a clearly marked gap and list the follow-up question; never fill it with a plausible number.
- [productService]: what they bought and used.
- [resultMetric]: the headline outcome (a percentage, hours saved, revenue). Use it only if the answers support it; otherwise flag the mismatch.
Constraints:
- Structure: situation, problem in the customer's words, why they chose us, what changed, results with numbers, what is next. Grade-8 reading level, no adjectives about our product, no "trusted partner" clichés.
- The pull quote uses the customer's own phrasing; mark it "to confirm" if paraphrased.
- Approval email under 150 words: what they are approving, the two things they may change freely (quotes, numbers), where it will appear, and a reply-by date I will fill in.
- Before answering, check that every number in the draft appears in the answers or in [resultMetric].
Output format:
1. Interview question set: 12 questions in four groups with headings Before, Decision, Change, Results, each marked "answered" or "still to ask".
2. Case study draft: a title with the result in it, the six sections with headings, 450 to 550 words, the pull quote set apart.
3. Approval email: subject line and body.
4. Gaps to close: a bullet list of missing facts and who can supply each.
