Profit decline issue tree

This issue tree starts with a decline in profit and separates the possible causes into revenue and costs. That is a useful first split because profit is revenue minus costs, so the branches do not overlap and together cover the central equation. The next level turns broad drivers into tests: price, volume, and mix for revenue, and variable or fixed costs for spending. An issue tree is not a list of solutions. It is a structured set of questions that guides analysis. Use evidence to confirm or eliminate each branch, then expand only the areas that matter. It gives readers a concise reference they can reuse when discussing the result with colleagues.

Key decisions

  • Root issue: State the business question as a measurable problem.
  • MECE split: Separate profit drivers into revenue and costs.
  • Testable leaves: Turn each branch into an analysis to run.

When to reuse this

Use to frame an initial profitability case before collecting data.

FAQ

Frequently asked questions

What does MECE mean?01
Mutually exclusive, collectively exhaustive: branches do not overlap and cover the whole issue.
