The many streams within systems science have diversified perspectives, theories and methods, but have also complicated the field as a whole. This makes it difficult to understand and master the field.
Practical Tips For A Better Ebook Reading
Short introductions to fundamental questions of systems science are rare. Integrative visualizations have been included to highlight the relationships between concepts, perspectives and systems thinkers. Several new attempts have been made to define and organize system concepts and streams in order to provide greater overall coherence and easier understanding.
What skills are needed for the 21st century that have been neglected in the past?
It has become increasingly clear that the problems and challenges we face are highly interlinked, complex and multidisciplinary. A comparative study Wiek et al.
These three challenges are closely related to the three foundational aspects of systems science explored in this paper. The goal of this paper is to make key perspectives and concepts of systems thinking and systems science more understandable to researchers and to persons involved practically in fields such as education, consulting or management.
To achieve this goal in the limited space of this paper, emphasis will be on visual maps that help us to integrate systemic knowledge from diverse streams and to highlight relations. More detailed descriptions of the concepts mentioned can be obtained in the cited references. Troncale , p. Among other solutions, he recommends overcoming obstacles by use of graphic techniques.
There exist several definitions of systems science.
M'Pherson, , p. Heylighen, , p.
Systems science is a science whose domain of inquiry consists of those properties of systems and associated problems that emanate from the general notion of systemhood. Klir, , p. Systems science can be defined as the scientific exploration and theory of systems in the various sciences, such as biology, sociology, economics, etc.
Strijbos, , p. Klir , p. These three components will also be addressed in the three parts of this paper. The history of systems science has its beginnings in the years around Hammond, with the work of founding fathers such as Bertalanffy, Wiener, Rapoport, Boulding and Miller. The emergence of systems thinking is closely linked with the endeavour to overcome previous boundaries within academia and practice interdisciplinarity and transdisciplinarity. Terms were newly created or specified, such as feedback, autopoiesis, chaos and complexity.
These concepts received increasing interest in applied fields so that many methods and methodologies emerged that incorporated aspects of systems theory in order to improve practice systems approaches.
The goal is to better understand how different sorts of systems work and how to deal with complex situations and reduce unwanted side effects.
Over 40 years ago, Ackoff , p.
There is not a corresponding understanding concerning the content of systems science. On the contrary, there are dozens of small systems societies that speak to widely differing points of view as to what constitutes systems science for their members. Warfield, , p. The hypothesis of this paper is that steps towards a better integration of the systems field can be made by exploring and visualizing systems science as a system itself.
What function does systems science have within its larger system? What are the functions of the subsystems of systems science?
And how do the parts of systems science relate to each other and create a bigger whole? Many theoretical and practical problems cannot be understood and solved by a single discipline alone.
Interdisciplinarity involves work between fields and learning about each other, whereas transdisciplinarity involves work in which new shared concepts are needed, and work that bridges theoretical and practical issues.
Systems science grew out of the need to communicate across disciplinary boundaries. Rapoport, , preface. Today, systems science and the field of interdisciplinarity and transdisciplinarity still share many similar goals and partly overlap. Through maps of science, we can begin to see all that we know as landscape — viewed as if from above or from a great distance.

Science maps provide guidance for navigating, understanding and communicating the dynamic and changing structure of science and technology. What are the role, purpose and place of systems science in the landscape of the sciences?
How would a librarian classify the books in this field? Is systems science closer to computer science, or management, or theoretical biology, or is it more similar to mathematics?
Five horizontal system categories are combined with five vertical knowledge dimensions. The result is a visual map of the sciences with two axes.
M'Pherson , p. This diagram includes two further fields: systems science and systems design. Boulding , p. Systems design refers to the heterogeneous field of general methods and practices relevant for all applied fields. Banathy , p. A special feature of the systems movement is the fact that its important exponents come from very different science fields.
Many of the systems thinkers presented here are discussed in more detail in Ramage and Shipp Other visual representations of the systems field are given by Ison et al.

They are organized according to key contributions to the field, although most of these systems thinkers could be assigned to multiple places. The list is by no means exhaustive.
The names of those pictured are given in bold. The purpose of the map is to stimulate interest in and discussion on systems thinkers.
Most systems thinkers have developed their own unique understanding of systems definitions and concepts. Often, terms and concepts of systems theories are optimized for a certain field, such as for managers, social scientists or engineers. Part two, on the other hand, attempts to create a multidisciplinary view of systems.
The focus in this section is on different notions of defining systems and a variety of systems principles. The task of a general theory of systems would include that of defining a system, of formulating a taxonomy of systems, of singling out properties that various systems have in common, and of explaining how this approach can help us to a better understanding of our world.
Rapoport, , p. This situation demands from the subdisciplines within systems science increased collaboration to provide a coherent body of knowledge, including definitions, concepts, classifications and related general methods to deal with complex situations.
Additional educational strategies and tools are needed to facilitate teaching and learning systems science and to creatively apply its principles in a wide variety of settings.
What is a system?
U.S. Geological Survey
The concept of a system is one of the most widely used concepts in science, particularly in recent times. It is encountered in nearly all the fundamental fields of science, such as physics, chemistry, mathematics, logic, cybernetics, economics, linguistics, biology, psychology, as well as in the majority of engineering branches.
The next section takes a closer look at this problem and proposes a hierarchical approach to differentiating between several systems principles and types.
The founders of the systems movement stressed the importance of general systems principles and concepts. Today our main problem is that of organized complexity. However, they pop up everywhere in the biological, behavioral, and social sciences, and are, in fact, indispensable for dealing with living organisms or social groups. These principles comprise a core element of the author's intended future research.
Koshland, ; Elitzur, , in developmental psychology e. Piaget, ; Fischer, ; Commons et al. What kind of features does a system need in order that the parts can build an integrated whole, the system is able to adapt to changing environments and the system itself can finally be a functional part of a bigger group system and contribute to it?
In each step, the focus is changed to an additional type of functionality or process. The chosen key terms appear in quotation marks. Criteria for their selection were that they are short, easily understandable and can be used in several areas of application. Other synonyms might be more appropriate depending on the context and scientific perspective. More important than the terms themselves are the described functions behind the terms.
INTRODUCTION: BACKGROUND AND PROBLEM
This process of concept building and classification is not yet finished, it is still at an early stage, open to discussion and further improvement. In this general sense, every living cell is in the process of computing data—not just computers.
In this sense, it is enabled for innovation and evolution. We have thus reached a higher and emergent boundary level.

These aspects have parallels in many areas, for instance, about how to define characteristics of organizations Katz and Kahn, and how communities collectively manage common goods Ostrom, On the basis of the principles described here, a type of a system can be classified in terms of the most prominent or highest principle reached.
A company might behave on the market like an adaptive system react to changes to maintain identity or an innovative system intensive search for new solutions. Similarly, Morgan used system types to classify organizations. The aforementioned list of hierarchical systems principles and types needs further ground work to demonstrate its relevance in different areas of application.
If systems science is not a homogenous field, what subdisciplines belong to it and how do they relate to core functions and principles of systems? It should be possible to analyze how influential various traditions of systems science have been in establishing or clarifying some key systemic principles. There have been many historical overviews on the development of systems science e.
CHAPTER 13 System Analysis and Design
These traditions can be summarized as follows.
