How it works

Problem severity

How painful or urgent the problem is. The strongest ideas remove a pain people already work to get rid of, not a nice-to-have they could happily skip.

Signals that raise the score

  • People already spend time or money working around the problem
  • The pain shows up regularly, not once a year
  • Someone is measured on fixing it, so it has a budget owner
  • People describe it with frustration, not a shrug
  • Living with it has a real, visible cost

Signals that lower it

  • It is a small improvement on something that already works fine
  • Only you have noticed the problem so far
  • People agree it is annoying but no one has tried to fix it
  • The cost of doing nothing is close to zero
  • You first have to convince people they even have the problem

What this measures

Problem severity asks one blunt question: how badly does this problem need solving? The classic test is painkiller versus vitamin. A painkiller removes a pain someone already feels and is already trying to treat. A vitamin is a pleasant improvement they could skip without much regret.

The score is highest when the problem is frequent, expensive, and something the buyer is already spending time or money to deal with. It drops when the problem is occasional, mild, or hypothetical.

Why it matters

Severity sits upstream of almost everything else in a business. When the pain is real, the rest of the model gets easier: people pay more to remove sharp pain, they stick around because the need keeps returning, and they are easier to reach because they are already looking for a fix.

When the pain is mild, every other part of the business turns uphill. Pricing is hard, because nobody pays much to remove a minor annoyance. Retention is weak, because the need barely comes back. Acquisition is expensive, because you have to convince people they have a problem before you can sell the cure. A weak problem quietly taxes the whole idea.

How it affects your recommendation

A high severity score paired with a clear buyer is the strongest possible start for an idea, and it pulls the overall recommendation toward pursue or validate.

A low score rarely sinks an idea on its own, but it makes a high overall score very hard to reach, because so much else depends on it. When severity is low, the report usually points to one of two moves: narrow the idea toward the sharper version of the problem hiding inside it, or aim it at a buyer who feels the pain far more acutely than the average person does.

Example

Two ideas can share the same shape and have completely different severity. "An app that reminds you to drink water" and "software that flags missed medication doses for elderly patients in assisted living" are both reminder tools. One addresses a mild, optional habit. The other addresses a problem with health consequences, a clear buyer, and an obvious cost to getting it wrong. Same mechanism, very different severity, and that gap shows up in nearly every other factor.
