Win-Loss Analysis SKILL.md
The Win-Loss Analysis skill makes Claude, Codex or another AI agent set up and run a programme that asks buyers why they chose or rejected you. It analyses CRM outcomes, selects recent wins, losses and no-decisions, runs neutral buyer interviews, codes reasons with a consistent taxonomy, compares CRM and buyer reasons, finds patterns by segment and competitor and turns findings into actions with owners.

When a deal is lost, the CRM usually says "price" or "no decision", typed by a rep at the end of a long quarter. Buyers tell a different story: the demo didn't show their use case, the competitor's champion was stronger, procurement found a security gap, or the case for change was never made. Win-loss analysis asks buyers directly why they chose, or didn't choose, you, then turns the patterns into changes in positioning, product, pricing, enablement and process.
This skill sets up and runs a win-loss programme: selecting deals, interviewing buyers (not reps), coding reasons, analysing patterns by segment and competitor, and turning findings into actions with owners.
Operating principles
- Talk to buyers, not reps. Rep-entered loss reasons are often wrong or incomplete.
- Include wins. Knowing why you win is as useful as knowing why you lose.
- Neutral interviewers. Buyers speak more freely to someone outside the sales team.
- Code consistently. A stable reason taxonomy makes patterns visible over time.
- Close the loop. Every quarter, findings must change something.
Deal selection
| Deal type | Why include |
|---|---|
| Recent losses to competitors | Direct competitive insight |
| Recent wins | What works, to repeat |
| No-decision outcomes | Often the biggest hidden loss |
| Churned customers (early) | Where the sale promised more than the product delivered |
| Large or strategic deals | Highest value lessons |
Aim for 10 to 20 interviews per quarter, balanced between wins and losses, focused on deals closed in the last 90 days.
Reason taxonomy (starting point)
| Category | Examples |
|---|---|
| Product fit | Missing capability, integration gap, usability |
| Value and price | Price, ROI unclear, packaging mismatch |
| Sales experience | Responsiveness, demo relevance, trust in rep |
| Competitor strength | Better relationship, perceived leader, bundling |
| Risk and trust | Security, compliance, references, company size |
| Decision process | Champion left, budget frozen, no urgency |
| Implementation | Effort, timeline, change management |
When to use, and when not to
Use it when win rates change, when entering new segments, after pricing or packaging changes, when a competitor gains ground and as an ongoing quarterly programme.
Don't use it for general customer research about usage (customer-research-interviews) or for one-off competitor tracking (competitive-intelligence).
Inputs to ask for, in one message
- CRM export of closed deals for 6 to 12 months: outcome, reason, competitor, size, segment, cycle length.
- Contacts for recent wins and losses who agreed to be contacted.
- Existing loss reason fields and any past win-loss work.
- Budget for incentives and an interviewer (internal neutral team or third party).
- Stakeholders who will act on findings (product, sales, marketing, leadership).

When to use this skill, and when not to
Use it when win rates change, when entering new segments, after pricing or packaging changes, when a competitor gains ground and as an ongoing quarterly programme.
When a deal is lost, the CRM usually says price or no decision, typed by a rep at the end of a long quarter. Buyers often tell a different story: an irrelevant demo, a stronger champion elsewhere, a security gap or no clear reason to change. Win-loss finds out which.
Don’t use it for general usage research (use Customer Research) or ongoing competitor tracking (use Competitive Intelligence).
Example prompts
- “Set up a quarterly win-loss programme.”
- “Our CRM says we lose on price. Is that true?”
- “Write a win-loss interview guide.”
- “Analyse these 15 interviews and find patterns.”
- “Why are no-decision deals rising?”
Example output
The skill returns a fixed structure. A shortened example for an imaginary site:
# Win-loss readout: Q3 2026, example HR software Deals: 15 interviews (8 losses, 5 wins, 2 no-decision) CRM said: price (most losses) Buyers said: competitor demoed payroll integration with their provider; value unclear Actions 1. Demo library by payroll provider (enablement) 2. Mid-market value calculator (marketing) 3. Battlecard landmines on integration depth (PMM)
Buyers are interviewed by someone outside the sales team, because they speak far more freely to a neutral person.
What the agent needs from you
The skill asks for a CRM export of closed deals with outcome, reason, competitor, size and segment, contacts for recent wins and losses, existing loss reason fields, budget for incentives and an interviewer, and the stakeholders who will act on findings.
How this skill hands off to related skills
Win-loss findings change the rest of the set: battlecards in Competitive Intelligence, Positioning and Messaging, Pricing, Sales Enablement and the ICP.
How to run Win-Loss Analysis step by step
- Install the skill as
win-loss-analysis/SKILL.md. - Export closed deals for 6 to 12 months.
- Select recent wins, losses and no-decisions.
- Recruit buyers through a neutral interviewer.
- Interview and code reasons with quotes.
- Share the readout and track actions.
Situations this skill handles
Win-loss programmes meet familiar obstacles. The skill handles these situations:
| Situation | What the skill does |
|---|---|
| Buyers will not talk | Surveys, third parties and higher incentives |
| Few deals | Interviews most of them |
| Sales resists | Shares wins too |
| Product disputes findings | Shares recordings and revenue at stake |
| Enterprise deals | Two or three stakeholders per deal |
| Rising no-decisions | Builds the case against the status quo |
What makes this skill different
Most loss analysis reads CRM fields. This skill asks buyers, includes wins and no-decisions, codes reasons consistently so trends show over time and compares what the CRM said with what buyers said.
Every quarter ends with actions and owners across positioning, product, pricing and enablement, followed by win rate tracking.
Practical tips from real projects
- Buyers, not reps.
- Include wins.
- Neutral interviewers.
- Close the loop every quarter.
A worked example: an HR software company saw most losses recorded as price in the CRM. Fifteen buyer interviews told another story. In mid-market deals, buyers chose a competitor because its demo showed payroll integration with their own provider, while the company demoed generic features. Price came up only when value was unclear. Actions included a demo library by payroll provider, a value calculator for mid-market buyers and new battlecard landmines about integration depth. Mid-market win rates rose over the next two quarters and price-related losses fell.
Deal selection balances recent losses to competitors, recent wins, no-decision outcomes, early churn and large or strategic deals, focused on those closed in the last 90 days so buyers remember clearly.
The reason taxonomy starts with seven categories: product fit, value and price, sales experience, competitor strength, risk and trust, decision process and implementation. Each deal gets one primary and up to two secondary reasons, each with a quote, and the taxonomy changes only when patterns demand it so trends stay comparable.
The interview guide covers what prompted the search, who was involved, which options were considered including doing nothing, which criteria mattered, how each vendor performed, what tipped the decision and what the losing vendors could have done differently. For wins it adds what nearly made the buyer choose someone else.
Comparing CRM reasons with buyer reasons is often the most useful table in the readout: price frequently turns out to mean unclear return on investment, lost to competitor often means a more relevant demo, no decision usually means no compelling reason to change and missing feature can mean a workaround nobody showed.
Findings are shared by audience: product hears about capability gaps and integrations, sales about demo relevance and competitor handling, marketing about messaging and proof, and leadership about trends, revenue at stake and decisions needed.
Recruiting works best with a short, respectful request from someone outside the sales team: a clear purpose, a 20-minute call, an incentive or charity donation and a promise that nothing said will be used to sell. Response rates rise when the request comes soon after the decision and when buyers know their feedback will be acted on.
The programme is measured by interviews completed each quarter, the share of deals with buyer-verified reasons, win rates in segments where actions were taken and the share of actions completed on time. These numbers show whether win-loss is changing the business or just producing reports.
When buyers will not talk, short surveys, third-party interviewers and higher incentives help. When deals are few, interviewing most of them still reveals patterns. When sales resists, sharing wins alongside losses shows the programme helps reps win more. When product teams dispute findings, recordings and quotes tied to revenue at stake settle the discussion.
Each quarter ends with a short readout and a list of owned actions.
Frequently asked questions
What is win-loss analysis?
Interviewing buyers after a decision to learn why they chose or rejected you, then coding reasons and acting on patterns.
Why not rely on CRM loss reasons?
They are entered by reps under time pressure and are often wrong or incomplete; buyer interviews give a truer picture.
Should wins be included?
Yes. Knowing why you win is as valuable as knowing why you lose.
Who should interview buyers?
Someone outside the sales team, either an internal neutral team or a third party.
How many interviews per quarter?
Often 10 to 20, balanced between wins and losses and focused on deals closed in the last 90 days.
What happens to findings?
A quarterly readout with actions and owners, then tracking of win rates in the affected segments.
