ValidationProven Pattern

Validate demand manually before building expensive automation

Insight from Krish Ramineni

When to use

When considering building automated systems or infrastructure for a new product feature - first test the concept with manual processes, concierge service, or Wizard-of-Oz approaches to confirm real demand exists.

Don't do this

Building sophisticated automation, integrations, or infrastructure before validating that customers actually want the solution - wasting engineering time on features nobody uses.
