Why This Bearing Matters
Most product teams skip directly from "understanding the problem" to "designing the solution." They identify customer pain points and immediately start building.
The SOUND phase forces you to slow down and ask: What assumptions are we making that haven't been tested? Where do customers believe one thing, but reality shows another? What failures are hiding in the current system?
The Core Concept: The Crucible
This phase is the crucible. It burns away untested assumptions and reveals what's actually true.
Skip it, and you build on fantasy. Do it well, and your playbook is built on evidence. SOUND exposes the gaps between what customers say and what they do, between what you believe and what's real.
The Shift
"Customers say they want this"
→
"Evidence shows they actually do this"
"We believe our idea will work"
→
"We've tested the critical assumptions"
"We're differentiated"
→
"Our value curve diverges on what customers value"
"Trust your gut"
→
"Validate through experiment"
