よくある質問

よくある質問

What is an issue tree and when do I use it?

An issue tree is a hierarchical diagram that breaks a complex problem into its component sub-issues, ensuring every branch is mutually exclusive and collectively exhaustive (MECE). Use it when scoping a consulting engagement, structuring a business case, or organizing a root-cause analysis.

Can I use this for McKinsey-style problem solving?

Yes. Issue trees are a core McKinsey and BCG tool. The generator follows the MECE principle and produces Pricing / Volume / Mix decompositions, cost-structure breakdowns, or any hypothesis-driven framework you describe.

Can I customize the diagram after it is generated?

Yes. Describe the example and request changes in the chat — the AI adjusts branches, renames nodes, adds sub-issues, or reframes the root question in seconds.

Can I export the diagram?

Yes. Export as PNG from the editor toolbar, or copy the diagram to paste into presentations and reports.

Is it free to use?

With a free account, you can create diagrams for free. No credit card is needed. You can save your work and generate diagrams.
