Win-loss analysis is a regular review of closed deals, won and lost, that uses buyer interviews and deal records to learn why buyers decided as they did.
Running a win-loss program
A team picks a set of recently closed deals each month or quarter, records the rep's view of each outcome, then has someone outside the deal team interview the buyer. The interview is one of three sources that work best together, alongside the rep's debrief and the CRM and call data.
The buyer's view matters because reps often misread their own losses: in Anova Consulting's studies, reps had the full and accurate reason 40% of the time, part of it 28% of the time, and were completely wrong 32% of the time. Each outcome is coded to fixed reasons, and the counts show what to change. For a sales manager, the useful codes name the buyer evidence that was missing, so the same gap can be found and coached in open deals. Our deal risk guide lists that evidence by stage.
Example
This example is illustrative. A rep logs a lost $50,000 deal as "price." The buyer interview says the CFO never saw why the problem mattered this year, and price only came up after that. Coded to evidence, the loss is "signer never heard the case." The manager finds four open deals with the same gap, and each rep plans a call with the champion to bring the signer in, working out the ask with Caty first.
In each rep's 1:1 that week, the manager's question comes straight from the coded loss: "Has the person who signs heard, from someone on their own team, why this has to be fixed this year?" "The champion says the CFO is on board" is the answer that lost the $50,000 deal. A date, a name and what the CFO said is the answer that keeps the next one.

FAQ
Who runs win-loss analysis?
RevOps, enablement or product marketing usually owns the program. Someone outside the deal team should interview the buyer, because buyers are more candid with a neutral person. Front-line managers use the findings on their open deals.
What is the difference between win rate and win-loss analysis?
Win rate is a number: deals won divided by deals closed. Win-loss analysis explains the number, by asking buyers and reviewing deals to find out why each one was won or lost.
How often should a sales team do win-loss analysis?
Most teams do best with a monthly review of five to ten recently closed deals, with the counts reviewed each quarter. A small regular cycle keeps findings fresh enough to use on deals that are still open.
