A Chief of Staff operates as the executive's force multiplier — managing strategic priorities, aligning cross-functional teams, and ensuring that decisions translate into action. Unlike an executive assistant who manages schedules and logistics, a CoS owns outcomes: they run operating rhythms, prepare decision memos, manage special projects, and serve as the connective tissue between the executive and the rest of the organization.
While both roles support executives, the distinction is scope and authority. An EA manages the executive's time, calendar, and communications. A Chief of Staff manages the executive's priorities, decisions, and organizational alignment. A CoS typically has authority to make decisions on the executive's behalf, lead cross-functional initiatives, and represent the executive in meetings.
CoS-OS™ (Chief of Staff Operating System) is a proprietary methodology created by Michelle DeFouw that gives leaders a structured framework for executive-level operations. It includes the D.A.R.E. framework (Decisions, Alignment, Rhythm, Execution), an archetype assessment system, and practical tools for running operating rhythms, decision processes, and strategic planning.
Find MAC offers three structured engagement levels. The 30-Day Sprint establishes your AI foundation. The 90-Day Sprint scales what works across departments with custom workflows and ROI tracking. The 365-Day Sprint is a full enterprise transformation that embeds AI into your operating model and builds internal AI capability.
Find MAC serves two audiences: Chiefs of Staff and executive operators who want a structured methodology for strategic execution, and organizations looking for structured AI transformation from initial assessment through full enterprise deployment.
The CEO Archetype Quiz is a free assessment that identifies your executive leadership style across four archetypes. It takes about 5 minutes to complete and you receive personalized results with actionable recommendations for your leadership development.
The Chiefs of Staff Circle is a community hosted on Mighty Networks for current and aspiring Chiefs of Staff. Inside you'll find peer discussions, resource libraries, the free webinar series, and direct access to the CoS-OS™ methodology in practice. You can join through the link on the Executive OS page or in the footer navigation.
