Executive Certificate: Chief of Staff (CoS)

Your Playbook for Strategic Execution and Executive Partnership

The Chief of Staff (CoS) role is one of the most influential and rapidly growing in modern business, yet also one of the most ambiguous. What does a CoS actually do? How do you effectively support a CEO and drive results without formal authority? And how do you prepare for this unique, strategically vital position?

We have designed a program that gives you the specific tools, frameworks, and insights needed to succeed as a Chief of Staff—from day one through planning your next career move.

What is a Chief of Staff? From Enigma to Strategic Partner

Many confuse the CoS with an Executive Assistant, COO, or Head of HR. Our course begins with a clear definition: the CoS is a strategic force multiplier for a leader, operating horizontally across the entire organization. We explore the role's history, its key archetypes (Gatekeeper, Implementer, Strategist), and why it has become indispensable in today's fast-paced business world.

This course provides you with a concrete framework for every key CoS function—knowledge often missing even from MBA programs:

·        How to represent the CEO in meetings without overstepping authority.

·        How to filter information and protect the leader's focus.

·        How to drive cross-functional projects without direct reports.

·        How to build trust with your principal, even in challenging dynamics like micromanagement.

Course Structure: Theory + Practical Application with AI

The program consists of 15 in-depth, text-based lessons, divided into 3 parts. Each lesson is built on a unique two-part model:

·        📖 Part 1: Theory & Frameworks. We explain the core concepts and models essential for understanding the CoS function (e.g., organizational structures, influence models, strategic analysis basics).

·        🧠 Part 2: Practical Case Study + Gemini. We take a real-world business situation a CoS faces and show you how to solve it step-by-step, using AI (Gemini) as your analytical assistant to draft plans, emails, and strategies.

Every lesson provides actionable knowledge and a practical tool you can immediately apply in your work.
