Case structure builder
Start from the decision metric. Add branches you can size. Five templates. Not a leaked framework packet.
Say it as a decision: metric, time horizon, constraint. Then the tree hangs off that sentence.
Restore operating profit in 12 months. First branch to size: Revenue (price × volume × mix)
Compare your tree to a worked one in the issue tree examples, then run a timed structure drill.
FAQ
Is this an official MBB framework?
No. Five common trees: profitability, growth, market entry, M&A, operations. Interviewers grade whether the branches hang off the decision, not the template name.
What does Grade MECE actually check?
Thin trees, “and” buckets, and leftover words like etc. It does not replace a human. Circle the first branch you can put a number on.
