Win/loss analysis
Win/loss analysis is the practice of investigating closed deals (won, lost, no decision) to extract patterns that improve future deals.
The classical version of win/loss runs on a quarterly cadence. A researcher or PMM interviews a sample of buyers after the deal closed, writes up themes, and presents findings to leadership. The deliverable is a slide deck or a report.
The method works in theory. In practice it has three weaknesses. It is slow, so findings arrive too late to influence the next deal. It is recency-biased, because researchers interview the buyers who remember the most and are willing to talk. And it is sample-limited, because nobody has time to interview every buyer.
There is a newer version, continuous win/loss, that runs on call recordings and CRM data instead of interviews. Every deal becomes a data point automatically. Patterns surface in weeks, not quarters. The trade-off is that raw call data is harder to interpret than a structured interview. The two methods are complementary, not substitutes.
The Amdahl view
Quarterly win/loss is too slow to influence the next deal. Continuous win/loss is the version that compounds. If the sales team cannot ask why did our last five Series B losses cite pricing and get an answer cited to calls, the win/loss program is a research project, not a learning system. The point of win/loss is to change behavior in the next deal, not to fill a slide at the end of the quarter.
