Siemens CEO Roland Busch: Seven Rules for Managing Extreme Complexity

Busch maintains a strict inbox discipline, capping his messages at 100 to prevent visual clutter and ensure rapid response times. He discards corporate formalities in favor of brevity, often limiting his replies to two-letter answers like "OK" or "No." This approach extends to his calendar; he refuses to schedule recurring meetings with direct reports, preferring that his team initiates contact only when specific issues require his intervention. He argues that he has no interest in entertaining staff, nor should they feel obligated to entertain him.

His decision-making process is rooted in his background in theoretical physics. When faced with complex corporate challenges, Busch systematically de-layers the problem, discarding secondary noise to isolate the core variables. He applies this same reductionist logic to his physical routine, preparing his gym clothes the night before to eliminate morning decision fatigue. Even his travel schedule follows a pre-set protocol designed to minimize jet lag, while his downtime is strictly compartmentalized. By returning to playing the guitar, he forces his brain to abandon professional demands entirely, achieving a mental reset that he finds essential for sustaining his long-term performance.
