About this routine

The IDEO four categories selection process helps teams avoid picking only the safest ideas after a brainstorming session. By distributing raw concepts into four distinct buckets, teams ensure that bold, unconventional, and high potential ideas remain in play alongside practical choices.

Instead of relying solely on standard dot voting, which often favors predictable solutions, this method forces explicit evaluation across varying risk profiles. Ideas are sorted into rational picks, delightful details, personal darlings, and long shot wildcards.

Running this structured workshop yields a balanced portfolio of concepts ready for immediate testing and rapid prototyping.

Why this routine works

Prevents teams from defaulting to safe or conventional solutions
Preserves high risk, high reward ideas during selection
Creates a balanced portfolio of concepts for rapid prototyping

FAQ

The four categories are the most rational idea, the most delightful idea, the darling idea, and the long shot idea.

How long does an IDEO Four Categories selection session take?

A standard team session takes 45 minutes from setting up the grid to selecting concepts for prototyping.

Why use four categories instead of simple dot voting?

Dot voting often selects safe, conventional ideas. Four categories preserve wild and high delight concepts alongside practical ones.
