# win-loss-analysis — Day 4 research skill The Example 1 Day 4 skill. Reads your won + lost sales-call transcripts and writes a pattern-level analysis to `marketing/win-loss/win-loss.md`. This is the evidence base under positioning, messaging, and ICP — every claim in those docs should trace back to something a real buyer said here. --- ## When to use - Day 4 of Example 1: before `/icp-research` + `/positioning`, so the strategy reads from real buyer language - You have a fresh batch of 5+ won/lost call transcripts - A quarter closes and you want to refresh why deals moved - Churn spikes and you need the pattern, not the anecdote ## When NOT to use - For a single account's interview prep (use `/customer-interviews` — not in V2 quickstart) - For behavioural simulation of a buyer (use `/icp-behavioural` — not in V2 quickstart) - When you have fewer than ~5 transcripts — patterns need volume; below that you get anecdotes, not signal ## Two rules apply before any analysis - **Redact PII first** — [`.claude/rules/pii-redaction.md`](../../rules/pii-redaction.md). Mask end-customer names, emails, and account numbers before processing; keep roles, company, and deal context. - **Bind every claim to evidence** — [`.claude/rules/evidence-bound-outputs.md`](../../rules/evidence-bound-outputs.md). Every pattern cites a verbatim quote + speaker, or it lowers its confidence. No invented quotes. ## How it works 1. Inputs: sales-call transcripts (Gong, Fireflies, Otter, Granola, Zoo
