Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful function.
Operations research, often shortened to the initialism OR, is a branch of applied mathematics that deals with the development and application of analytical methods to improve decision-making. Although the term management science is sometimes used similarly, the two fields differ in their scope and emphasis.
Anthony Stafford Beer was a British theorist, consultant and professor at the Manchester Business School. He is best known for his work in the fields of operational research and management cybernetics.
Within personality psychology, personal construct theory (PCT) or personal construct psychology (PCP) is a theory of personality and cognition developed by the American psychologist George Kelly in the 1950s. The theory addresses the psychological reasons for actions. Kelly proposed that individuals can be psychologically evaluated according to similarity–dissimilarity poles, which he called personal constructs. The theory is considered by some psychologists as forerunner to theories of cognitive therapy.
Morphological analysis or general morphological analysis is a method for exploring possible solutions to a multi-dimensional, non-quantified complex problem. It was developed by Swiss astronomer Fritz Zwicky. General morphology has found use in fields including engineering design, technological forecasting, organizational development and policy analysis.
Design research was originally constituted as primarily concerned with ways of supporting and improving the process of design, developing from work in design methods. The concept has been expanded to include research embedded within the process of design and research-based design practice, research into the cognitive and communal processes of designing, and extending into wider aspects of socio-political, ethical and environmental contexts of design. It retains a sense of generality, recognising design as a creative act common to many fields, and aimed at understanding design processes and practices quite broadly.
Russell Lincoln Ackoff was an American organizational theorist, consultant, and Anheuser-Busch Professor Emeritus of Management Science at the Wharton School, University of Pennsylvania. Ackoff was a pioneer in the field of operations research, systems thinking and management science.
Soft systems methodology (SSM) is an organised way of thinking applicable to problematic social situations and in the management of change by using action. It was developed in England by academics at the Lancaster Systems Department on the basis of a ten-year action research programme.
In planning and policy, a wicked problem is a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognize. It refers to an idea or problem that cannot be fixed, where there is no single solution to the problem; and "wicked" denotes resistance to resolution, rather than evil. Another definition is "a problem whose social complexity means that it has no determinable stopping point". Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems. Due to their complexity, wicked problems are often characterized by organized irresponsibility.
Management cybernetics is concerned with the application of cybernetics to management and organizations. "Management cybernetics" was first introduced by Stafford Beer in the late 1950s and introduces the various mechanisms of self-regulation applied by and to organizational settings, as seen through a cybernetics perspective. Beer developed the theory through a combination of practical applications and a series of influential books. The practical applications involved steel production, publishing and operations research in a large variety of different industries. Some consider that the full flowering of management cybernetics is represented in Beer's books. However, learning continues.
The issue-based information system (IBIS) is an argumentation-based approach to clarifying wicked problems—complex, ill-defined problems that involve multiple stakeholders. Diagrammatic visualization using IBIS notation is often called issue mapping.
Critical systems thinking (CST) is a systems approach designed to aid decision-makers, and other stakeholders, improve complex problem situations that cross departmental and, often, organizational boundaries. CST sees systems thinking as essential to managing multidimensional 'messes' in which technical, economic, organizational, human, cultural and political elements interact. It is critical in a positive manner because it seeks to capitalize on the strengths of existing approaches while also calling attention to their limitations. CST seeks to allow systems approaches such as systems engineering, system dynamics, organizational cybernetics, soft systems methodology, critical systems heuristics, and others, to be used together, in a responsive and flexible way, to maximize the benefits they can bring.
Compendium is a computer program and social science tool that facilitates the mapping and management of ideas and arguments. The software provides a visual environment that allows people to structure and record collaboration as they discuss and work through wicked problems.
Robust decision-making (RDM) is an iterative decision analytics framework that aims to help identify potential robust strategies, characterize the vulnerabilities of such strategies, and evaluate the tradeoffs among them. RDM focuses on informing decisions under conditions of what is called "deep uncertainty", that is, conditions where the parties to a decision do not know or do not agree on the system models relating actions to consequences or the prior probability distributions for the key input parameters to those models.
Confrontation analysis is an operational analysis technique used to structure, understand and think through multi-party interactions such as negotiations. It is the underpinning mathematical basis of drama theory.
A decisional balance sheet or decision balance sheet is a tabular method for representing the pros and cons of different choices and for helping someone decide what to do in a certain circumstance. It is often used in working with ambivalence in people who are engaged in behaviours that are harmful to their health, as part of psychological approaches such as those based on the transtheoretical model of change, and in certain circumstances in motivational interviewing.
DSRP is a theory and method of thinking, developed by systems theorist and cognitive scientist Derek Cabrera. It is an acronym that stands for Distinctions, Systems, Relationships, and Perspectives. Cabrera posits that these four patterns underlie all cognition, that they are universal to the process of structuring information, and that people can improve their thinking skills by learning to use the four elements explicitly.
David Allen Hickling was a British architect, strategic choice process consultant, author, game designer, and an authority in the field of toy forts and castles.
Colin Eden was a professor in management science and operations research at Strathclyde University.
Jonathan Vivian Rosenhead is a British mathematician, operational researcher and Labour Party activist.
