MECE issue tree · IN SHORT
Make an unclear problem manageable before choosing solutions. The skill sharpens the root question, splits it into two to five branches and attaches hypotheses, evidence needs and ownership.
Your brief
Our workshop revenue is falling. We do not yet know whether there are fewer bookings or a different mix of workshops.
Possible draft
Start with places sold and revenue per place, using the same period and definitions. First action: produce that breakdown from booking records. A causal conclusion must wait for evidence.
01 / THE FOUNDATION
A confirmed root question, an issue tree with evidence needs, overlap checks and one action within a working day.
02 / SEE HOW IT WORKS
Our workshop revenue is falling. We do not yet know whether there are fewer bookings or a different mix of workshops.
Start with places sold and revenue per place, using the same period and definitions. First action: produce that breakdown from booking records. A causal conclusion must wait for evidence.
This example shows the approach. It is not a client result or a guarantee of a particular outcome.
03 / GET STARTED
Summarise the situation and complication, then agree one question without a hidden solution.
Choose a logical split, check overlaps and gaps and attach a falsifiable hypothesis to each branch.
Identify useful first evidence and one bounded investigation for tomorrow.
04 / MAKE IT YOURS
Take the instructions, add your own context and review the draft. You stay in control.
