This knowledge area (KA) provides a guide to some of the major developments in systems sciencesystems science, which is an interdisciplinary field of science that studies the nature of complexcomplex systemssystems in nature, society, and engineeringengineering.

This is part of the wider systems knowledge which can help to provide a common language and intellectual foundation, and make practical systems conceptsconcepts, principlesprinciples, patternspatterns and tools accessible to systems engineeringsystems engineering (SE) as discussed in the Introduction to Part 2.

Topics

Each part of the SEBoK is divided into KAs, which are groupings of information with a related theme. The KAs, in turn, are divided into topics. This KA contains the following topics:

Introduction

Systems science brings together research into all aspects of systems with the goal of identifying, exploring, and understanding patterns of complexitycomplexity and emergenceemergence which cross disciplinary fields and areas of application. It seeks to develop interdisciplinary foundations which can form the basis of theories applicable to all types of systems, independent of elementelement type or application; additionally, it could form the foundations of a meta-discipline unifying traditional scientific specialisms.

The History of Systems Science article describes some of the important multidisciplinary fields of research of which systems science is composed.

A second article presents and contrasts the underlying theories and origins behind some of the classic system approachessystem approaches taken in applying systems science to real problems.

People who think and act in a systems way are essential to the success of both research and practice. Successful systems research will not only apply systems thinkingsystems thinking to the topic being researched but should also consider a systems thinking approach to the way the research is planned and conducted. It would also be of benefit to have people involved in research who have, at a minimum, an awareness of system practice and ideally are involved in practical applications of the theories they develop.

-This Knowledge Area (KA) provides a guide to the major developments in [[Systems Science (glossary)]] which is a collective term for a group of theory and practice developed by researchers and practitioners applying [[Systems Thinking (glossary)]] to a range of problems.  This knowledge is not specific to Systems Engineering, but is part of a wider systems body of knowledge.  We have not attempted to capture all of the system knowledge here, but to identify those aspects relevant to the systems engineering body of knowledge.

+==Introduction==
+Systems science brings together research into all aspects of systems with the goal of identifying, exploring, and understanding patterns of {{Term|Complexity (glossary)|complexity}} and {{Term|Emergence (glossary)|emergence}} which cross disciplinary fields and areas of application. It seeks to develop interdisciplinary foundations which can form the basis of theories applicable to all types of systems, independent of {{Term|Element (glossary)|element}} type or application; additionally, it could form the foundations of a meta-discipline unifying traditional scientific specialisms.
-[[Systems Thinking (glossary)]] is an approach to understanding or intervening in systems, based on the principles and concepts of systems. In the [[System Thinking]] KA we give some basic definitions of systems thinking and the systems theory which supports it.
+The [[History of Systems Science]] article describes some of the important multidisciplinary fields of research of which systems science is composed.
-The development of these theoretical ideas to a point where they can be consider be part of the cannon of Systems Thinking is like any other branch of science not a straight forward of linear process.  [[General System Theory (glossary)]] [[Acronyms|(GST)]] (von Bertalanffy, 1968) enables comparisons between systems that rely on different technologies, judging the goodness or completeness of a system, and developing domain-independent systems approaches which can form the basis of disciplines such as Systems Engineering.  While many researchers and practitioners have created GST concepts, these tend to be a stepping stone to theories and approaches.  This situation is made worse by the variety of domains and disciplines in which systems research is conducted and reported.
-While the System of [[System-Concepts (glossary)]] presented in the [[Systems Thinking]] Knowledge Area is a powerful set of ideas for better understanding all kinds of systems it is not rigourous or complete.
-This Knowledge area describes the most important movements in Systems Science and presents a guide to the overlapping and sometimes contraditory theories it has created and used.
+A second article presents and contrasts the underlying theories and origins behind some of the classic {{Term|Systems Approach (glossary)|system approaches}} taken in applying systems science to real problems.
+People who think and act in a systems way are essential to the success of both research and practice. Successful systems research will not only apply {{Term|Systems Thinking (glossary)|systems thinking}} to the topic being researched but should also consider a systems thinking approach to the way the research is planned and conducted.
