Can my sales team do win-loss themselves?

No. The independence of the interviewer is the value. Buyers will not share with sales reps what they'll share with an independent researcher.

How many interviews per quarter is enough?

15-25 is the minimum that produces useful pattern-spotting. Below 15 you're working with anecdotes; 25+ produces robust quarterly segmentation.

How long should a win-loss programme run?

Continuous, by quarter. The value compounds — patterns that appear in 4 consecutive quarters carry more weight than single-quarter findings.

Win-Loss Analysis

Win-loss analysis is the structured practice of interviewing recent buyers — both those who chose you and those who chose a competitor — to surface the actual decision criteria, competitive perception and product gaps driving the buying outcome.

01/In Depth3–5 paragraphs

Internal sales-team explanations of wins and losses are systematically biased. Reps overweight skill in wins and pricing in losses. Independent third-party interviews surface the actual decision criterion, which is usually a mix of perceived risk, internal politics, and specific product/service gaps invisible to the sales team.

Standard format: 15-50 interviews per quarter (mix of recent wins and recent losses), trained third-party interviewers, structured findings with verbatim quotes, quarterly executive review.

Win-loss is highest-ROI for companies with sales cycles of weeks to months, where the buyer can articulate their decision process. Lower-ROI for very long enterprise cycles (where the decision is too institutional) or very short consumer purchases (where the decision is too automatic).

Common outputs feed sales enablement (better battle cards), product roadmap (specific gaps surfacing repeatedly), pricing (where price sensitivity is materially different from internal assumptions), and competitive positioning.
