『The Manager's Path』要約

Camille Fournier’s "The Manager's Path" is a pragmatic guide to engineering leadership, tracing the arc from individual contributor to senior executive. Fournier, a former CTO of Rent the Runway and managing director at Two Sigma, structures the book as a chronological ladder: mentor, tech lead, engineering manager, director of engineering, VP, and finally CTO. Each rung gets its own chapter that pairs the new responsibilities with the specific skills that must be developed before moving up. The book’s distinctive contribution is its insistence that management is a separate craft from engineering, one that must be learned deliberately. Fournier walks through concrete practices: running effective one-on-ones, writing performance reviews, giving feedback, hiring and interviewing, managing interns, and handling underperformance. She devotes significant attention to the tech lead role as a bridge between writing code and managing people, and to the "manager of managers" transition, where a director must delegate through team leads rather than direct reports. Later chapters address org design, cultural stewardship, and the CTO’s dual technical and political responsibilities, including how to manage up to a CEO and board. A recurring theme is that many new managers fail because they cling to coding as an identity and avoid the uncomfortable people work. Fournier also discusses when management is the wrong path, encouraging engineers to consider staying technical. The result is a widely used reference for both new managers and companies building engineering career ladders.
