Prioritize it.

Use when you need to prioritize ideas for high impact.

Thankfully, not all ideas are created equal. And often, it’s not until the Post-its meet the floor during Impact x Doability that this reality begins to sink in.

This is one of the Move Fast drills we use during Blitzes to sort through the multitude of emerging solutions that have been generated by each team, typically from a series of Be Bold and Let Go Drills. Impact x Doability helps us to focus quickly on the ideas with the highest potential to solve our challenge.

Encourage dialogue around the definitions of impact and doability before sorting—then, let the team(s) have at it!


  • Definition of high impact

  • Definition of what makes a solution doable

  • Reduced set of high-potential ideas



Blue Tape


Step 1
Introduce the Impact x Doability Drill.

Step 2
Use blue tape to create a large L-shaped space. Label the vertical axis “Impact” with “Very Little” at the bottom-most point and “Extraordinary” at the top-most point. Label the horizontal axis “Doability” with “Nearly Impossible” at the left-most point and “Dead Simple” at the right-most point.  

Step 3
Have Wrong Thinkers use Post-its to describe impact, placing them on the outside of the vertical axis.

Step 4
Have Wrong Thinkers use Post-its to describe doability, placing them below the horizontal axis.

Step 5
Instruct Wrong Thinkers to position the ideas generated from the Let Go Drills in the Impact x Doability space—with everyone placing ideas at the same time.

Step 6
Ask Wrong Thinkers to dot vote the three ideas their team is most excited about exploring further.

Encourage all Wrong Thinkers to participate with placing the ideas rather than telling one or two teammates where the ideas ought to be placed in the Impact x Doability space. 
If there is a disagreement with placement, move it, and discuss why you moved it with the group.
