COS helps builders, GCs, and subs run every project on-time, on-margin, and cash-positive. Your membership includes our Foundation Playbook \(dripped over 6 weeks\) and weekly Q&A. Upgrade anytime to: Diagnostic \(one-time blueprint & ROI\), Operator \(predictable cost/schedule\), or Portfolio \(governance at scale\). You’ll implement simple cadences, bulletproof change control, disciplined WIP/cash, and field rhythms that stick.
