All types of organizations, for profit, not-for-profit, lawful, and unlawful, must be relentless in highly competitive, and constantly evolving environments. Every day iconic brands like Sears, Kodak, and Blockbuster vanish. Managers in lawful companies face disruptive technologies, groundbreaking new products, and competition from new entrants. Every organization must manage its way through a rapidly shifting world, or else fail. Yet some organized crime syndicates last decades despite massive law enforcement efforts and rival gangs directed at their daily demise. The American Mafia, which burgeoned during Prohibition in the 1920s, still operates in the twenty-first century. The Sinaloa Cartel remains the largest smuggler of drugs into the US, despite jailing its leader, El Chapo Guzmán, in a US supermax prison. How do these criminal syndicates survive, and even thrive? They apply fundamental economic principles to devise management practices that channel their heinous members' self-interest to achieve the syndicates' objectives. Relentless uses the most unexpected organizations, crime syndicates, to elucidate essential economic concepts that allow all leaders to build stronger, more robust companies. These concepts align the organization's business strategy and employee empowerment, incentives, and corporate culture. These principles attract the right people to create resourceful, market-obsessed, and relentless high-performance teams. Understanding the management practices devised by mobsters illustrates the economic concepts that lawful managers also must heed. While lawful managers cannot simply follow the business practices of mobsters, they must apply the same fundamental principles described in Relentless. "In war, the better led, more effectively run team wins, regardless of moral right or wrong. In Relentless , we get a fascinating window into the murky world of organized crime - from the Mafia to Drug Cartels - and find that the same holds true. As mundane as it sounds, the frightening bosses who orchestrate the wrongdoing that simultaneously terrifies and mesmerizes us are, in the end, talented leaders and managers. There's much we can learn from them." - General Stanley McChrystal , Former commander of US and International Security Assistance Forces Afghanistan and the former commander of Joint Special Operations Command "This intriguing and thoughtful book illustrates the power of sound economic thinking in understanding organizations. It takes the concepts that help us understand successful business enterprises and shows that the same concepts are at work in successful criminal enterprises. In so doing it validates the power of the underlying economic concepts while offering a fascinating window into some of the most long-lived criminal organizations." - Charles Plosser , Former President of the Federal Reserve Bank of Philadelphia "Drawing on insights from perhaps the most unlikely of sources-organized crime-Jerold Zimmerman, the co-architect of organizational architecture theory, and Daniel Forrester, CEO of THRUUE Inc. provide unique insights of how effective leaders rely on both incentives and values/culture to build successful organizations. Because mobs must overcome so many challenges in order to succeed, Relentless provides especially compelling illumination of the Zimmerman-Forrester valuable leadership model." - Mark Zupan , President, Alfred University "Focusing on what make mobster enterprises successful and what leads to their failures, Zimmerman and Forrester provide an intriguing economic analysis of organized crime enterprises and derive corporate governance lessons that are applicable to legitimate enterprises." - Thomas Z. Lys , Eric L. Kohler Professor Emeritus, Kellogg School of Management, Northwestern University " Relentless provides a vivid reminder that long-term survival of any business, legitimate or illegitimate, requires creative thinking and adherence to key business principles." - Cliff Owens , Vice President (retired), Medtronic " Relentless deploys the novel device of comparing subjects that on the surface seem to have little in common-lawful and unlawful organizations- to identify important management principles while educating the reader about life and leadership in the criminal underworld. In this regard, Zimmerman and Forrester have really hit the mark. And they do all of this in a highly entertaining manner. Well done." - Graham McDonald , Senior Vice President (Retired), Great-West Financial " Relentless is thought provoking and very enlightening in terms of driving managers of lawful organizations to really understand the essential elements of management and leadership and how they must be tailored to their unique circumstances." - Jay Busch , Former President, Triax Telecommunications Jerold L. Zimmerman is a globally recognized business professor and author of seven books. Accounting for Decision Making and Control is in its 10th edition
