(2026-07-03) Nurijanian Crux Skill

George Nurijanian has a "Find the Strategic Crux" skill based on Rumelt's book. Most strategy work in product orgs stalls in the same place. Everyone agrees something needs to change. Nobody can name the core reason the gap exists. So the team writes pillars, bins roadmap items underneath them, and calls it strategy. The Find the Strategic Crux skill exists for that moment. It is a guided five-step problem-solving sequence inside PM OS. You start with a messy or unclear strategy situation. You end with a named crux and a tested recommendation. Your company knowledge stays with you. The skill supplies the step-by-step structure and the questions that keep you from skipping the hard parts..... Find the Strategic Crux is one skill inside AI PM OS, an AI operating system for product managers. It sits alongside company context, two hundred other skills, and eight guided workflows. Run a crux analysis on a strategy problem here. Then feed the output into opportunity mapping, decision work, or stakeholder prep without retyping the diagnosis.
