The unmet needs

Pains and gains with no offer element against them, ranked by severity.

The part

What it is

A severe pain with nothing against it is either the next thing to build or the reason a segment is not yours. Both are decisions.

It is worth distinguishing needs nobody serves from needs a competitor serves. The second is a competitive gap; the first may be an opportunity.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.

Pain or gain
The need in question, held in the same vocabulary as the map.
Reference shared type
Priority
Ranked by severity and frequency, which is what turns the list into a roadmap.
Priority shared type
Served elsewhere
Whether a competitor addresses it, which changes the decision entirely.
Choice shared type
