Book excerpt: Envision this scenario: An industrial manufacturer is breaking itself in three, and its board chair asks you, the chief financial officer, to step up to the helm of one of the spin-offs. You will take charge of everything, from plant operations and product marketing to human resources and governance practices. Are you ready to lead? In The Leader's Checklist, 10th Anniversary Edition: 16 Mission-Critical Principles, world-renowned leadership expert and Wharton professor Michael Useem shows you how to lead through any challenge—and shares how ITT's Denise Ramos did just that when she encountered this situation. In this illuminating guide, Useem offers a Leader's Checklist that will help you develop your ability to make good and timely decisions in unpredictable and stressful environments—for those moments when leadership really matters. To illustrate the principles, Useem examines where leaders go right—and wrong. He looks at:How Ramos, the former CEO of ITT, turned around the once-struggling enterprise; How AIG's tone-deaf response to the tumultuous events of the global financial crisis left the company vulnerable to one of the greatest corporate collapses in business history; andHow Virginia Rometty, the former executive chair of IBM, acquired and integrated a cloud-computing company to help turn around IBM's fortunes. Based on Useem's own research experience and an array of leadership investigators, thinkers, and practitioners, The Leader's Checklist offers actionable insights you can put into practice as a leader today.
