Extreme weather events, oil spills, bank failures, massive tech shifts, cyber attacks and terrorist attacks, civil unrest, epidemics and pandemics, asset bubbles, fiscal crises, and energy price shocks. Organizations are operating in increasingly complex and turbulent worlds that require them to navigate chaos and the dynamics of change. Leveraging positive organizational energy, collective design thinking and strategic super-flexibility, Tkaczyk provides an alternative paradigm for organizational change and development. Energize-Redesign-Gel (ERG), human-centered and business-focused, is a powerful design-inspired strategy for re-imagining your business and leading positive organizational change. Filled with ready-to-use worksheets, tools and templates (You’ll save hours of time!), it’s ideal for executive and change leadership teams. A brilliant sourcebook!”

Organizations with deep learning cultures are shown to be more competitive and successful in the marketplace. What’s great about Bart’s work is that he recognizes the role that learning and development can play in affecting positive change in people and companies. In Leading Positive Organizational Change, Bart introduces a new framework that involves a cycle of positive action and strategic learning that leads to sustained and effective change. And then he takes the framework and offers imminently practical and easy-to-use resources that can help any team create successful change efforts. This book will help many organizations emerge from the challenging times of today better than they were before.”

Like no other scholar, Bart Tkaczyk knows in his writings to touch the head, the heart and the hands! With Leading Positive Organizational Change, he not only offers a conceptual model in 3 chapters that most OD practitioners will recognize and will help them in their daily practice to understand what change processes evoke in their organization. On top of that the book provides the reader with a Toolbox of 30 tools to apply the model in their own jobs! Tkaczyk's book is a ‘must read’ and even more so a ‘must use’ book for anyone who is involved with leading change in their organization!”

The model and practices in this book represent, perhaps better than any other resource today, the effective blending of sound theory and relevant practice on the topic of change leadership. The literature on this topic abounds with approaches taken from a dizzying array of perspectives, often based on limited practice and devoid of any deeper understandings. In the end, the anchor of good practice often comes from seeking out enduring principles and finding ways to make them useful. From this perspective, Tkaczyk’s work continues to demonstrate the important contributions of the informed scholar-practitioner in the management and human resources fields. Certainly, the book will impact the actions of global managers seeking to lead the change process in organizations in more predictable and reliable ways.”

Dr. Bart Tkaczyk continues to deliver yet another typically pragmatic message dealing with effective organizational development, based on sound academic foundations involving strategic management approaches coupled with positive leadership. What distinguishes this new offering, compared to writings by others employing similar managerial catchwords, is his ability to inject a dramatic input of practicality into the mode of delivering procedures for change that are original, workable, understandable and effective by means of a 'Toolbox Modality'. On this you have my word!”

The book by Dr. Bart Tkaczyk advances our understanding of the process of instigating and sustaining a positive organizational change. It elucidates the underlying factors and dynamics that yet are rather underexplored and thus brings about unique added value for both scholars and practitioners.”

Too many books in this market are more theoretical, but the tool box makes this one really good for someone wanting help in actually doing OD... A short book with good tools that could be used as a practical additional text in either an OD or HRM class.”


Thomas C. Vandiver Bicentennial Chair in Business, Director of the Center for Executive Succession, Darla Moore School of Business, University of South Carolina

This is a refreshing new angle on a topic that requires almost by definition energy and genuine enthusiasm.

Dr Bart Tkaczyk writes with feeling and an almost religious zeal but the material is all the more welcome for it. 

There are great insights here. Very definitely highly recommended!”

Dr. Bart Tkaczyk lives and breathes positive Organization Development (OD).

Dr. Bart Tkaczyk is passionate about leadership and implementing change in a positive and impactful manner. If I could summarize him in three words it would be – energetic problem-solver.”

DEANNA ROCKEFELLER, MBA, Global Technology and Workforce Development Partnerships at Lockheed Martin

The book follows Drucker famous statement: plans are only good intentions unless they immediately degenerate into hard work. With a workbook included it not only provides the theory but concrete guidance for action. In turbulent times we need to see innovation in the practice of management – to which this book contributes.”


DR. RICHARD STRAUB, Founder & President, Global Peter Drucker Forum

Leading Positive Organizational Change provides an innovative framework with an immensely helpful set of practical tools for navigating organizational change through radically changing times. The ERG approach synthesizes and builds on the latest research in positive organizational scholarship (POS), addressing a crucial need in this time of turbulence and unrest. It's an energizing book and an invaluable asset for leaders and teams across a wide range of organizations.”

As the cliché goes ‘Change is the only constant’. If your organization is experiencing change by design or due to global turmoil, this book is a great guide to tide over the changes. It will help any organization go through a framework model to negotiate the change and bring about a positive outlook both in the organizations and its individuals. The book brings in a new way of thinking and applying this critical thinking in practice.”


CHERIAN VARGHESE, MBA, Regional Managing Director & VP of ASEAN & South Asian Growing Economies (SAGE) at Oracle

A concise book packed with both theoretical and practical insights, Leading Positive Organizational Change couldn’t have been a more timely resource for leaders and companies in such turbulent times as these. Tkaczyk offers a reflective yet empirically-relevant discourse about the way organizations could be (re)energized to shift from status quo to significance through an explorative, developmental, and interventional approach to change. If you are looking for a proven model of change that drives positive results in current, complex times, this book is the secret sauce. It will definitely change the way you view change. The impact is one of positive deviance – mindset, behavioral, and organizational change!”
