This document discusses the need for organizations to reinvent their management models for the 2020s and beyond. It argues that while business models have changed due to new technologies and customer demands, organizational models have not fundamentally changed since the 1990s. The COVID-19 crisis both exposed weaknesses in current models but also showed that organizations can overcome bureaucracy with urgency. The document proposes 10 "ground rules" for reinventing management, such as aligning around a clear purpose and definition of winning, focusing resources on top priorities, eliminating matrix structures, and making customer value the core operating principle.
