This is a structured business problem solving framework that walks you through McKinsey-style consulting analysis from problem definition to final deliverables. It breaks down complex business questions using MECE principles and issue trees, then generates dummy page layouts before collecting data and producing actual PowerPoint decks with proper Excel backing. The progressive disclosure architecture is smart: it only loads methodology docs when you hit each step, keeping context usage down by about 70%. What's genuinely useful here is the dependency-aware page generation in version 3.1, so you can pick up multi-page reports across different conversations without losing track of which slides need data from others. The whole flow takes 90-110 minutes versus what would normally be days of manual work.
