1Mckinsey ConsultantMcKinsey Consultant packages McKinsey Problem Solving 101 and 102 into an agent skill that walks a solo builder or small team from a vague commercial question to a structured answer and slide-ready narrative. Phase one defines the problem, applies MECE decomposition, and builds a hypotheses tree so analysis stays assumption-driven rather than anecdotal. Phase two designs how each insight should appear on slides—argument types and McKinsey-style layouts before heavy data work. Phase three focuses on targeted data collection, professional deck generation, and refinement loops. The README positions total effort at ninety to one hundred ten minutes and claims roughly ninety-five percent time savings versus three-to-five-day manual consulting-style work. It suits indie founders sizing a niche, preparing investor or partner conversations, or framing a new product line without hiring a strategy shop, provided you accept that quality depends on the data your agent can gather and your willingness to iterate on the generated deck.690installs
