Book excerpt: Monica Sharma describes how we can source our inner capacities and wisdom to manifest change that embodies universal values such as dignity, compassion, fairness, and courage. Drawing on more than twenty years of work for the United Nations and elsewhere, she presents a radical new approach to transformational leadership, one that creates systems of change where everyone can engage—not just analysts and policy-makers. Demonstrating that we all can be architects of a new humanity, Monica demystifies policy-making, planning, and implementation so that everyone can play an informed and strategic part in eradicating the world’s most intractable problems. Using real-life examples from around the world, she shows how our innate characteristics of universal compassion, equity impulse, and human capability can create new patterns that effectively address major challenges such as gross inequality, unbridled hate, conflicts based on social identity, and the never-enough mindset of greed. Written in a straightforward, accessible style, Radical Transformational Leadership outlines a path-breaking paradigm shift that is already generating equitable and sustainable results across the globe.

Available in PDF, EPUB and Kindle. Book excerpt: Learn to flourish as a leader so that a mindset of growth, optimism, and positivity spreads to your employees and shows up in the customer experience. In the world of work, the single greatest asset of successful individuals, teams, and organizations is their mindset—what happens in between their ears. It’s not the corporate strategy, the sales compensation plan, or the market segments they’re pursuing. It is what each leader, team member, and employee chooses to focus on, believe, and create for themselves and others. 7 Principles of Transformational Leadership presents the fundamental concepts whose implementation will result in dramatic revenue, performance, and relationship growth. Specifically, leaders will learn to: Live their professional and personal lives with unbridled purpose and passion. Execute strategic priorities more effectively and with accelerated results. Retain the brightest and best talent. Have employees, key stakeholders, and managers enthusiastically follow them. Be exemplars of innovation, growth, and positive mindsets. Cascade excellence throughout their organizations. You may have employees with all the talent in the world, but you’ll never achieve remarkable results until you change your employees’ mindset. 7 Principles of Transformational Leadership will help you convert your human potential into accelerated business results.

Book excerpt: A new, tenth anniversary edition of the leadership classic that was hailed as one of the 100 Best Business Books of All Time. In his exciting and timeless business parable, The Radical Leap, Steve Farber explores an entirely new leadership model, one in which leaders aren't afraid to take risks, make mistakes in front of employees, or actively solicit employee feedback. His book dispenses with the typical, tired notions of what it means to be a leader. Farber's modern parable begins on a sunny California beach where he has a strange and unexpected encounter with a surfer named Edg. Despite his unassuming appearance, the enigmatic Edg seems to know an awful lot about leadership and this brief interaction propels Steve into an unforgettable journey. Along the way, he learns about Extreme Leadership--and what it means to take the Radical Leap: Cultivate Love Generate Energy Inspire Audacity Provide Proof Geared to people at any level who aspire to change things for the better, The Radical Leap is creating legions of Extreme Leaders in business, education, non-profits and beyond.

The crisis is of long standing and its signs are widespread. Most proposals for improving management address one element of the crisis at the expense of the others. The principles described by award-winning author Stephen Denning simultaneously inspire high productivity, continuous innovation, deep job satisfaction and client delight. Denning puts forward a fundamentally different approach to management, with seven inter-locking principles of continuous innovation: focusing the entire organization on delighting clients; working in self-organizing teams; operating in client-driven iterations; delivering value to clients with each iteration; fostering radical transparency; nurturing continuous self-improvement and communicating interactively. In sum, the principles comprise a new mental model of management. Author outlines the basic seven principles of continuous innovation The book describes more than seventy supporting practices Denning offers a rethinking of management from first principles This book is written by the author of The Secret Language of Leadership—a Financial Times Selection in Best Books of 2007.

Book excerpt: A WALL STREET JOURNAL BEST-SELLING BOOK NAMED BY THE WASHINGTON POST AS ONE OF THE 11 LEADERSHIP BOOKS TO READ IN 2018 Radical Inclusion: What the Post-9/11 World Should Have Taught Us About Leadership examines today’s leadership landscape and describes the change it demands of leaders. Dempsey and Brafman persuasively explain that today’s leaders are in competition for the trust and confidence of those they lead more than ever before. They assert that the nature of power is changing and should not be measured by degree of control alone. They offer principles for adaptation and bring them to life with examples from business, academia, government, and the military. In building their argument, Dempsey and Brafman introduce several concepts that illuminate both the vulnerability and the opportunity in leading today: Radical Inclusion. Fear of losing control in our fast-paced, complex, highly scrutinized environment is pushing us toward exclusion―exactly the wrong direction. Leaders should instead develop an instinct for inclusion. The word “radical” emphasizes the urgency of doing so. The Era of the Digital Echo. The speed and accessibility of information create “digital echoes” that make facts vulnerable, eroding the trust between leader and follower. Relinquishing Control to Preserve Power. Power and control once went hand in hand, but no longer. In today’s environment, control is seductive but unlikely to produce optimum, affordable, sustainable solutions. Leaders must relinquish and share control to build and preserve power. The principles discussed in Radical Inclusion are memorable and the book is full of engaging stories. From a young vegan’s confrontation with opponents in Berkeley to a young lieutenant’s surprising visitor during the Cold War, from a reflection on the significance of Burning Man to a discussion of challenges faced in the Situation Room, Radical Inclusion will provide you with leadership tools to address real leadership challenges.

Available in PDF, EPUB and Kindle. Book excerpt: Many companies are relying on a business model that is fundamentally suited to a different era. Now, organizations are under pressure from new trends such as digitization and servitization. Trying to adapt to a new environment, they risk relying on improvements that only scratch the surface of developing a radically different value proposition. Based on rigorous research into companies that have successfully and radically redesigned their business models, Radical Business Model Transformation shows why they made the leap, what they had to do to achieve it and how it has transformed the potential for their organizations. This book is a step-by-step guide for leaders who want to seize the opportunity of new business models and gain a competitive advantage. It explains how to assess the status quo, identify the value of future business models and develop a transformation path. It also provides advice on how to involve both the leadership team and all other employees in order to implement successful business model transformation. Illustrative case studies of organizations that have crossed the line to a more transformative business range from exponential-growth companies like Netflix and global players like Xerox, SAP and Daimler to mid-sized hidden champions like Knorr-Bremse and LEGIC. Radical Business Model Transformation is essential reading for business leaders, transformation experts and MBA students interested in ensuring that their business model is future-proof and can withstand the new proliferation of innovations that are set to transform the business landscape. Online supporting resources include a business model transformation calculator to help design your transformation path.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines numerous topic areas that are considered to be especially relevant for making a strategic leader development investment. The topics covered are areas that have theoretical and empirical connections to important aspects of growth, change, adult development, and underlying abilities, skills, and competencies needed to lead effectively in times of great complexity. In addition, these are investment areas identified by the U.S. Army--a world-class organization faced with the need for radical transformation--as particularly relevant for success and survival. This book identifies key concerns in developing leaders and leadership, and in transforming organizations to better meet the challenges of a complex world. There are two aspects of this book that distinguish it from the numerous existing volumes on leadership in the scholarly and popular-press literatures. Most important, the overarching focus of the present book is on development. There are many offerings on the topic of leadership, but relatively few that focus on leader development--especially from a scholarly, academic perspective. Also, this volume offers a unique perspective in examining those underlying psychological competencies and processes that are viewed as especially relevant for leader development. The chapters that are collected in this edited volume were originally commissioned by the U.S. Army Research Institute as "white papers" to better help Army officers and researchers understand important issues in leader development. The present organization of the papers is around four central themes: a) Accelerating Leader Development, b) Cognitive Skills Development, c) Developing Practical and Emotional Intelligence, and d) Enhancing Team Skills.

Book excerpt: Wall Street Journal Bestseller From the acclaimed author of Turn the Ship Around!, former US Navy Captain David Marquet, comes a radical new playbook for empowering your team to make better decisions and take greater ownership. You might imagine that an effective leader is someone who makes quick, intelligent decisions, gives inspiring speeches, and issues clear orders to their team so they can execute a plan to achieve your organization's goals. Unfortunately, David Marquet argues, that's an outdated model of leadership that just doesn't work anymore. As a leader in today's networked, information-dense business climate, you don't have full visibility into your organization or the ground reality of your operating environment. In order to harness the eyes, ears, and minds of your people, you need to foster a climate of collaborative experimentation that encourages people to speak up when they notice problems and work together to identify and test solutions. Too many leaders fall in love with the sound of their own voice, and wind up dictating plans and digging in their heels when problems begin to emerge. Even when you want to be a more collaborative leader, you can undermine your own efforts by defaulting to command-and-control language we've inherited from the industrial era. It's time to ditch the industrial age playbook of leadership. In Leadership is Language, you'll learn how choosing your words can dramatically improve decision-making and execution on your team. Marquet outlines six plays for all leaders, anchored in how you use language: • Control the clock, don't obey the clock: Pre-plan decision points and give your people the tools they need to hit pause on a plan of action if they notice something wrong. • Collaborate, don't coerce: As the leader, you should be the last one to offer your opinion. Rather than locking your team into binary responses ("Is this a good plan?"), allow them to answer on a scale ("How confident are you about this plan?") • Commit, don't comply: Rather than expect your team to comply with specific directions, explain your overall goals, and get their commitment to achieving it one piece at a time. • Complete, not continue: If every day feels like a repetition of the last, you're doing something wrong. Articulate concrete plans with a start and end date to align your team. • Improve, don't prove: Ask your people to improve on plans and processes, rather than prove that they can meet fixed goals or deadlines. You'll face fewer cut corners and better long-term results. • Connect, don't conform: Flatten hierarchies in your organization and connect with your people to encourage them to contribute to decision-making. In his last book, Turn the Ship Around!, Marquet told the incredible story of abandoning command-and-control leadership on his submarine and empowering his crew to turn the worst performing submarine to the best performer in the fleet. Now, with Leadership is Language he gives businesspeople the tools they need to achieve such transformational leadership in their organizations.

Available in PDF, EPUB and Kindle. Book excerpt: In Mission-Driven Leadership, Mark Bertolini, the long-time chairman and CEO of Aetna, the Fortune 500 health insurance company, reveals that genuine leadership is not about dollars and market share but about improving lives and communities. Mark Bertolini didn't get to the corner office through traditional means. He grew up in a blue-collar neighborhood in Detroit. Early in his career, he was known for his bare-knuckled leadership and hard driving competitiveness that helped him to turnaround several companies. But his ambition came at a cost as he ran roughshod over his colleagues and employees, and spent time away from his family. Two events served as wakeup calls for the hard-charging Bertolini. First his son Eric was diagnosed with incurable cancer, and Bertolini found himself confronting the healthcare industry firsthand, not as an executive, but as the parent of a deathly ill child, determined to save his son's life. And miraculously, after a year in the hospital, often at death's door--Eric was twice given last rites--his son recovered. The second wakeup call was a skiing accident several years later in which Bertolini broke his neck. As his life unraveled in the face of years of chronic pain, therapy, and medication, he realized he had to reinvent himself, emotionally, spiritually, and as a leader--or go under. Mission-Driven Leadership speaks to the lessons Bertolini learned about empathy, about helping employees and Aetna's customers take better care of themselves and each other, about the need to "find the divine in me," and the importance of getting out to meet with employees and customers face-to-face in town halls to truly discover their needs and better serve them.
