Problem Validation vs. Solution Validation

Two separate tests: whether the problem is real and painful enough that people already do something about it, and whether your particular solution is one they would use and pay for.

Why does Problem Validation vs. Solution Validation matter?

Skipping the first and going straight to the second is how founders build good solutions to problems nobody has. They are also failed differently: a problem that is not painful cannot be rescued by better execution, while a validated problem with the wrong solution just means try again. Knowing which one you failed determines whether you iterate or pivot, and getting that wrong costs months.

What does Problem Validation vs. Solution Validation look like in practice?

Problem validation asks: has this practice already tried to fix scheduling — hired someone, bought a tool, built a spreadsheet? Money or effort already spent is the strongest evidence a problem is real. Solution validation comes after, and asks whether *your* approach is one they will adopt given what they already do. A practice that has never tried anything is telling you something about the problem, not about your product.

What are the common mistakes with Problem Validation vs. Solution Validation?

  • Treating interest in the solution as proof the problem exists.
  • Validating the problem with people who are not in your ICP.
  • Concluding the problem is invalid when the solution was the part that failed — and abandoning a real opportunity.
  • Looking only for confirmation. The useful interview is the one that could change your mind.
