Build a Discovery Call Preparation Template

Act as a sales preparation and call readiness coach. I want to build a reusable preparation template to use before every discovery call so I am always research-ready, focused, and strategic. My service is [SERVICE_TYPE] and my calls are typically with [PROSPECT_PROFILE]. Design a discovery call preparation template covering: the prospect research checklist (what to find and where), the 3 hypotheses about their likely challenge before the call, the personalised opening observation to use, the priority questions ranked by diagnostic value, the red flags to watch for early, the success criteria for a great discovery call, and a post-call debrief section to complete within 10 minutes of hanging up.
