Rank It.

Use when you have generated many possibilities and need to focus your efforts on those that really matter.



  • A “stack ranked” set of possibilities

  • Focus on where to place effort

  • Preservation of “lesser” things (that might later prove to be important)

A large empty surface (wall or floor).

Blue tape


Step 1
Use blue tape to create your sorting space on a wall or the floor. For example, a vertical line labeled "Impact", with the top being High Impact and the bottom being Low Impact.

Step 2
Distribute the Post-its to be sorted evenly among Wrong Thinkers. 

Step 3
Have Wrong Thinkers position their Post-its where they believe they belong in the sorting space.

Step 4
Give Wrong Thinkers permission to reposition Post-its if they don't agree with placement. Encourage them to discuss with their fellow Wrong Thinkers why they are repositioning them.

Step 5
[Optional] If you narrow the set further, give three green dots to each Wrong Thinker and ask them to vote on their top priorities.

A helpful tip:

Stack ranking is typically done on a vertical axis—with the upper point being highly important or critical and the bottom point being inconsequential. 

A useful variation on this is to create three rows and to stack rank within each row:

Top Row: Transformative (dramatic improvements, big change required)
Middle Row: Incremental (small improvements, less change required)
Bottom Row: Tablestakes (no choice, must be done)
