『The First 90 Days』要約

In The First 90 Days, Michael D. Watkins argues that career transitions are periods of heightened vulnerability and opportunity that demand deliberate management rather than improvisation. Drawing on research and his work advising executives, Watkins frames the first three months in a new role as a critical window for diagnosing the situation, securing early wins, and building the relationships and credibility needed for longer-term success. He introduces the STARS model to classify situations leaders inherit: Start-up, Turnaround, Accelerated Growth, Realignment, and Sustaining Success. Each demands a different approach, and misdiagnosing which one you face is a common and costly error. Other central frameworks include the breakeven point, the moment when a new leader has contributed more value than he or she has consumed, and the five conversations to have with your boss about situation, expectations, style, resources, and personal development. Watkins also covers negotiating success, achieving alignment, building teams, creating alliances, and managing yourself, including the advice to match strategy to situation rather than applying a single playbook everywhere. A distinctive emphasis is the distinction between taking charge in a new company versus a promotion within the same one, and the need to avoid the "action imperative," the trap of doing too much too soon before understanding context. The book closes by addressing acceleration through preparation before day one and ongoing self-management. Widely used by organizations for onboarding leaders, it remains a practical guide to transition management rather than general career advice.
