Design-Thinking - Empathize. Define. Ideate. Develop. Implement.

Framework

PSM (Problem · Solution · Market space)

The three spaces in the Growth Diamond Model where teams explore needs, solutions, and market fit.

Also called: Problem Solution Market space

PSM structures where design thinking work happens:

  • Problem space - empathize with users and define the right problem
  • Solution space - ideate and develop viable options
  • Market space - implement, launch, and grow adoption beyond early users

Many teams stop after building a solution. PSM explicitly extends work into market space - where products succeed or stall.
