This is the substantive scholarly work to provide a map of the state of art research in the growing field emerging at the intersection of complexity science and management studies.

From the winner of the INCOSE Pioneer Award 2022 The world has become increasingly networked and unpredictable. Decision makers at all levels are required to manage the consequences of complexity every day. They must deal with problems that arise unexpectedly, generate uncertainty, are characterised by interconnectivity, and spread across traditional boundaries. Simple solutions to complex problems are usually inadequate and risk exacerbating the original issues. Leaders of international bodies such as the UN, OECD, UNESCO and WHO — and of major business, public sector, charitable, and professional organizations — have all declared that systems thinking is an essential leadership skill for managing the complexity of the economic, social and environmental issues that confront decision makers. Systems thinking must be implemented more generally, and on a wider scale, to address these issues. An evaluation of different systems methodologies suggests that they concentrate on different aspects of complexity. To be in the best position to deal with complexity, decision makers must understand the strengths and weaknesses of the various approaches and learn how to employ them in combination. This is called critical systems thinking. Making use of over 25 case studies, the book offers an account of the development of systems thinking and of major efforts to apply the approach in real-world interventions. Further, it encourages the widespread use of critical systems practice as a means of ensuring responsible leadership in a complex world. The INCOSE Pioneer Award is presented to someone who, by their achievements in the engineering of systems, has contributed uniquely to major products or outcomes enhancing society or meeting its needs. The criteria may apply to a single outstanding outcome or a lifetime of significant achievements in effecting successful systems. Comments on a previous version of the book: Russ Ackoff: ‘the book is the best overview of the field I have seen’ JP van Gigch: ‘Jackson does a masterful job.

Product design is characterized by a steady increase in complexity. The main focus of this book is a structural approach on complexity management. This means, system structures are considered in order to address the challenge of complexity in all aspects of product design. Structures arise from the complex dependencies of system elements. Thus, the identification of system structures provides access to the understanding of system behavior in practical applications. The book presents a methodology that enables the analysis, control and optimization of complex structures, and the applicability of domain-spanning problems. The methodology allows significant improvements on handling system complexity by creating improved system understanding on the one hand and optimizing product design that is robust for system adaptations on the other hand. Developers can thereby enhance project coordination and improve communication between team members and as a result shorten development time. The practical application of the methodology is described by means of two detailed examples.

Managing Complexity is the first book that clearly defines the concept of Complexity, explains how Complexity can be measured and tuned, and describes the seven key features of Complex Systems: ConnectivityAutonomyEmergencyNonequilibriumNon-linearitySelf-organisationCo-evolution The thesis of the book is that complexity of the environment in which we work and live offers new opportunities and that the best strategy for surviving and prospering under conditions of complexity is to develop adaptability to perpetually changing conditions. An effective method for designing adaptability into business processes using multi-agent technology is presented and illustrated by several extensive examples, including adaptive, real-time scheduling of taxis, see-going tankers, road transport, supply chains, railway trains, production processes and swarms of small space satellites. Additional case studies include adaptive servicing of the International Space Station; adaptive processing of design changes of large structures such as wings of the largest airliner in the world; dynamic data mining, knowledge discovery and distributed semantic processing. Finally, the book provides a foretaste of the next generation of complex issues, notably, The Internet of Things, Smart Cities, Digital Enterprises and Smart Logistics.

Providing a critique of the ways that complexity theory has been applied to understanding organizations, and outining a new direction, this book calls for a radical re-examination of management thinking.

Michael Marti presents a complexity management model that is based on the reasoning that product architecture determines to a considerable extent how external complexity is translated into physical products. The model demonstrates a procedure to optimize a product’s architecture and is applied to several industrial products.

A fundamental problem of public sector governance relates to the very way of thinking it reflects; where organization is thought of as a ‘thing’, a system designed to deliver what its designers choose. This volume questions that way of thinking and takes a perspective in which organizations are complex responsive processes of relating between people. Bringing together the work of participants on the Doctor of Management program at Hertfordshire University, this book focuses on the move to marketization and managerialism, paying particular attention to human relationships and group dynamics. The contributors provide narrative accounts of their work addressing questions of management, pressures, accountability, responsiveness and traditional systems perspectives. In considering such questions in terms of their daily experience, they explore how the perspective of complex responsive processes assists them in making sense of experience and developing practice. Including an editors’ commentary which introduces and contextualizes these experiences as well as drawing out key themes for further research, this book will be of value to academics, students and practitioners looking for reflective accounts of real life experiences rather than further prescriptions of what organizational life ought to be.

A powerful guide to thinking and managing your way into the new economy. A how to think book for practicing managers.

Approaches to leadership and management are still dominated by prescriptions – usually claimed as scientific – for top executives to choose the future direction of their organization. The global financial recession and the collapse of investment capitalism (surely not planned by anyone) make it quite clear that top executives are simply not able to choose future directions. Despite this, current management literature mostly continues to avoid the obvious – management’s inability to predict or control what will happen in the future. The key question now must be how we are to think about management if we take the uncertainty of organizational life seriously. Ralph Stacey has turned to the sciences of uncertainty and complexity to develop an understanding of leadership and management as the ordinary politics of daily organizational life. In presenting organizations as a series of complex responsive processes, Stacey’s new book helps us to see organizational reality for what it actually is – human beings engaged in many, many local conversational interactions and power relations in which they negotiate their ideologically based choices. Organizational continuity and change emerge unpredictably, rather than as a result of any overall plan. This is a radically different picture from the one painted by most of the management literature, which explains "organizational continuity and change" as the realization of the global plans and choices of a few powerful executives within an organization. Providing a new foundation for understanding complexity and management, this important book is required reading for managers and leaders wanting to understand the reality of complexity in organizations, including those engaged in postgraduate studies in leadership, organizational behaviour and change management.

An insightful view on how to use the power of complexity theory to manage projects more successfully Current management practices require adherence to rigid, global responses unsuitable for addressing the changing needs of most projects. Complexity Theory and Project Management shifts this paradigm to create opportunities for expanding the decision-making process in ways that promote flexibility—and increase effectiveness. It informs readers on the managerial challenges of juggling project requirements, and offers them a clear roadmap on how to revise perspectives and reassess priorities to excel despite having an unpredictable workflow. One of the first books covering the subject of complexity theory for project management, this useful guide: Explains the relationship of complexity theory to virtual project management Supplies techniques, tips, and suggestions for building effective and successful teams in the virtual environment Presents current information about best practices and relevant proactive tools Makes a strong case for including complexity theory in PMI®'s PMBOK® Guide Complexity Theory and Project Management gives a firsthand view on the future of complexity theory as a driving force in the management field, and allows project managers to get a head start in applying its principles immediately to produce more favorable outcomes.
