Because winning the evaluation answers a question the buyer was not stuck on. Most of these deals are lost to indecision rather than to a competitor, and the people who saw it coming raised it to one person who could not act on it neutrally. The technical win is real. It is just not the thing that was blocking the decision.
The pattern is familiar enough that most presales leaders can describe it without being prompted. The team is selected. The architecture is approved. Security signs off. Somebody says you are clearly the strongest option.
Then the deal slows. The date moves once, politely. It moves again. Eventually it is not lost so much as abandoned, and the post mortem says budget, or timing, or priorities changed.
Those explanations are what people say. They are rarely what happened.

That changes what the technical win is worth. A technical evaluation establishes that the product can do the job. It does not establish that anybody is going to be held responsible for changing anything, which is the question that actually stalls these deals.
A buyer who is afraid of making a mistake is not reassured by a better demo. They are reassured by somebody removing the risk of deciding, and that work looks nothing like a proof of concept.
Winning the evaluation proves the product works. It proves nothing about whether the decision will be made.
This is where it stops being a buyer problem and becomes an internal one. An ongoing benchmark of how sales engineering teams actually run deals keeps producing the same three results.
The engineer in these deals is frequently the first person to know. They sit in the technical conversations where the real constraints surface, and they are the least incentivised to talk themselves into a close date.
And the warning goes to exactly one place: the person carrying the number that the warning threatens. Not because anyone is behaving badly, but because there is nowhere else for it to go.
The largest single thing that happens to a doubt is an informal mention. Said out loud, to a colleague, and recorded nowhere.
So a quarter later nobody can say: we flagged these deals, here is what we asked, and here is what closed. That sentence does not exist. Which means the same argument gets had again next quarter from zero, and the person who was right last time has no standing they did not have before.
Judgment that leaves no trace cannot turn into authority, and without authority the early warning is just a feeling somebody had.
Test the decision, not the product. If the evaluation is going well, the open question is no longer capability. It is what happens if nobody decides, who is accountable for that, and whether the cost of inaction has ever been said out loud by the buyer rather than by you.
Give the doubt a second destination. Today there is one, and it is the person who owns the number. That is a routing problem, not a loyalty problem, and it does not need a new tool.
Make the informal mention leave a trace. Capture it in any form and within a quarter you are holding evidence instead of a recollection.
