For an aerospace supplier, we built a program planner — one set of inputs, nine views, every figure from one model. This is one of its briefs, on an illustrative program. Move the levers; the brief rewrites itself. The client gets all nine views and every input.
This planner is one deliverable from one practice. Pricing models, cash forecasts, proposal libraries, hiring scorecards, brand systems, websites and operating dashboards are built the same way — by the consultant who wrote the plan, reviewed line by line, with a name on it when it ships. The client's version of this one has every input and every view, and stays in their own hands.
