Instructions for running this play

  1. Prepare a problem statement before the meeting and discuss it first thing. Draw the following fishbone diagram on a large surface and place a sticky note with the problem statement in the “head”
  2. Discuss relevant categories of causes of the problem with the group and place a sticky note with each category at the end of each “bone”. Categories could be:
    Methods, Machines (equipment), People (manpower), Materials, Measurement, Environment, Marketing
  3. Do Silent Storming on “Why does this happen?” in a Timebox of 10 minutes. Each participant plays back their findings on the map, placing each of their sticky notes on the branch of the appropriate category. A cause can be placed on several branches.
  4. Again ask “Why does this happen?” in a plenum about each cause. Write sub-causes branching off the causes. Continue to ask “Why?” and generate deeper levels of causes. Layers of branches indicate causal relationships. 
  5. When the group runs out of ideas, focus attention to places on the chart where ideas are few.
  6. Consider finishing off with a Who/What/When exercise or even a How Might We...

Tips to perfect this play

Master and adapt the play to fit your context and needs.

Tip: A shared understanding

Maps are for creating a shared understanding and exploring it across disciplines – between you, your team, and your stakeholders. Invite everyone relevant.

Tip: Reverse Fishbone

Start with the effect or problem and work backward to identify possible causes, challenging the team to think from a different perspective.

Tip: Multiple Fishbones

Use separate Fishbone Diagrams for different categories of causes, allowing for more focused discussions and analysis.

Tip: Follow-up with Five Whys

Consider combining with the Five Whys exercise
