Focusing tools
Tools for narrowing down — comparing, weighing and choosing among the options a group has generated. These are convergent: they end with fewer, stronger items than they started with.
- Voting — Surface the group's favourites with stars.
- Ranking — Put items in order of preference.
- Value / Doability — Score ideas on two dimensions and plot them.
- Evaluation Matrix — Score options against several criteria and compare them.
