Landsberg’s authority on management is not academic: it’s built from three decades inside the profession’s biggest advisory firms. He was a partner at McKinsey & Company for fifteen years before leaving in 1998 [1], later returning for a second McKinsey career as Director of the Firm’s Senior Partner Office for seven years [2], and has also held senior/partner roles at Heidrick & Struggles and, formerly, Korn Ferry [2][3]. Before McKinsey he worked at IBM and Andersen Consulting [1]. That arc, inside the firm that trains a large share of the Fortune 500’s future executives, then inside firms whose business is assessing and placing them, is the base his coaching authority sits on.
His training matches the ambition: an MA in Physics from Cambridge University, where he was an Entrance Scholar, and an MBA from Stanford’s Graduate School of Business [1]. It’s a coach’s credential, not a researcher’s: no doctorate, no peer-reviewed publication record behind it. His authority rests on decades of direct practice with senior leaders and boards, not published findings.
The book that made him known began as an internal document. While a partner responsible for McKinsey UK’s professional development [1], Landsberg wrote what became “the most frequently requested internal document in the whole of McKinsey during 1994” [1]. Two years later, he published it commercially as The Tao of Coaching (1996) [4], later reissued by Profile Books with two new chapters [5]. That book is where he coined the Skill/Will matrix, plotting a person’s capability against their motivation to prescribe the fix [6]. It sold, and kept selling: his coaching, motivation, and leadership books have sold more than 250,000 copies in fifteen languages [3], and include The Tao of Motivation, The Tools of Leadership, and Mastering Coaching [3].
Landsberg sits squarely on the devoted end of the spectrum: coaching senior leaders and advising boards on strategy and governance [2] has been his full-time work, not a side interest borrowed from another field. His word carries real weight on delegation diagnosis, executive coaching practice, and how top consulting and search firms develop talent: the terrain Skill vs. Will, still MC’s chosen name for his matrix, was built to serve. It carries less weight on the academic literature behind motivation or performance, since he cites no peer-reviewed record of his own. The throughline is a practitioner’s instinct for turning a messy diagnosis (can this person do it, do they want to?) into one page a manager can act on.
