The 12 most common discovery calls mistakes and how to fix them
Every mistake we see teams make with discovery calls — starting with the ones that cost the most and are the cheapest to fix.
Every discovery calls failure we have investigated maps to one of the mistakes below. They repeat because they are structurally easy to make.
Mistake one, the foundational one: reading a script instead of running a diagnosis. Fix by naming an owner and writing kill criteria before you spend a dollar.
Mistake two: mistaking volume for progress. Fix by making discovery-to-opportunity conversion the only weekly headline number.
Mistake three: buying tools before defining the workflow. Fix by drawing the workflow on paper first and buying only what the paper shows.
Mistake four: shipping without a quality gate. Fix by requiring a human eyeball on every artefact for the first four weeks.
Mistake five: ignoring the trigger. Discovery calls works when everything after discovery is downstream of what you learned in it; without a real trigger the model is guesswork.
Mistake six through twelve: cascade from the first five. Fix the top five and most of the others resolve themselves inside a month.
