Win Interview
A win interview is a win/loss interview conducted with a buyer who chose the vendor. In a standard program, win interviews make up roughly a third of the total interview count, commonly 10 out of a 20-to-30-interview target, with the remainder going to loss interviews.
The Confirmatory Role Win Interviews Play
Win interviews don’t carry the same weight as loss interviews for surfacing new concerns, because a win can happen for a range of reasons, favorable timing, a strong rep relationship, a competitor’s misstep, that are genuinely difficult to isolate. Their value is comparative. A concern that shows up repeatedly across loss interviews gets tested against the win set: if the same issue never appears in a single win interview, it points to a real, specific gap for a segment of buyers. If it does appear in wins, described as something the buyer noticed but ultimately tolerated, it suggests a lower-urgency problem rather than a dealbreaker.
What Win Interviews Cover
A win interview typically follows the same interview questionnaire structure as a loss interview, covering the buying process, evaluation criteria, competitive comparisons, and whether the vendor’s messaging resonated. The difference is in what the buyer is being asked to reflect on: not why they walked away, but what specifically tipped the decision, and whether any concerns nearly changed the outcome.
Why Win Interviews Alone Aren’t Enough
A program built entirely on win interviews would miss the sharper, more actionable signal that loss interviews tend to produce. Wins confirm what losses reveal; they rarely reveal something on their own that a loss interview set hasn’t already surfaced. This is the reasoning behind weighting a program toward losses rather than splitting interviews evenly.
A Practical Example
A program’s loss interviews repeatedly surface a specific integration gap as a reason deals didn’t close. Checking the ten win interviews against that finding shows the same gap mentioned twice, both times as something the buyer noticed but worked around rather than something that nearly killed the deal. That comparison tells the team the gap is real but not urgent, a conclusion the loss interviews alone couldn’t support.
