Scores a multi-business portfolio on a weighted GE-McKinsey 9-box via a bundled calculator, then measures how aggressively capital actually moves between business units year over year — grounded in McKinsey's own "Power of Capital Reallocation" research, which found companies that reallocate capital most aggressively deliver materially higher shareholder returns than those that don't. Use whenever the user wants a portfolio review, capital allocation recommendation, or investment committee prep, or when budget-setting is just "last year's allocation plus a few percent" with no real reallocation happening.
