The discovery mistake that kills your forecast

Most discovery calls end with the rep excited and the deal already dead.

The rep heard a problem, confirmed it out loud, booked the demo, and logged it as qualified. Three weeks later it slips. Then it slips again. Then it goes dark. The forecast was never real, because the discovery was never finished.

Here's the mistake: confirming a problem exists is not discovery. It's the first ten percent of it. The prospect says "yeah, our onboarding is a mess," the rep hears buying signal, and stops digging exactly when the real work starts. A confirmed problem is not a reason to buy. A quantified problem is.

The gap between "we have a problem" and "this problem costs us £40k a quarter" is the entire deal. That number is what your champion carries into the room you're not in. Without it, they're asking their CFO to fund a vibe. With it, they're presenting a business case. You don't close the CFO. Your champion does, using the number you gave them.

So discovery has one job: leave the call with a number the prospect believes, because they said it, not you.

Four questions that get you there:

1. 1. "How are you handling it today?" Not "do you have a problem." You know they do. You want the current workaround, because the workaround has a cost, and the cost is your wedge. The spreadsheet someone maintains by hand. The contractor they pay to paper over it. The deals they lose because the process is slow. Make the status quo visible and it stops being free.
2. 2. "What does that cost you?" Then stop talking. Most reps ask a version of this and rescue the silence before the prospect does the math. Let them do the math. If they can't, help them build it out loud: how many people, how many hours, how often, what's the fully-loaded rate. A number the prospect assembles themselves is a number they'll defend to their boss. A number you assert is one they'll forget by Friday.
3. 3. "What happens if you don't fix it this year?" This separates a priority from a nice-to-have. If the honest answer is "nothing much," you've just saved yourself a quarter of forecasting a deal that was never going to close. If the answer is "we miss the target / we lose the customer / I get the blame," now you know the stakes, and so do they, out loud, in their own words.
4. 4. "Who else feels this?" One person's annoyance doesn't fund a purchase. A problem three departments feel does. This maps the blast radius and hands you your multi-threading plan in the same breath. If only your single contact cares, you don't have a deal, you have a wish.

None of this is about interrogating the prospect. It's about doing the arithmetic together, so the cost of doing nothing becomes concrete and specific and theirs. The rep who quantifies wins the forecast. The rep who confirms fills the pipeline with deals that feel great and close never.
