How to solve each kind of case, and what every word means.

Internal / External

The first split for any 'why did this fall?'; one question rules out half the tree.

Why did it happen?
  • Internal: in our control
    • Our price and product
    • Our operations and people
  • External: outside it
    • Customers and demand
    • Competitors
    • Regulation and the economy
Top layer: keep it fixed Below: adapt to the case

Watch out: Ask 'only us, or the whole industry?' to know which side to open.
