 == What is a System? ==
-In general, a system is a set of interconnected elements that work together to achieve a common goal. The concept of a system can be applied to anything from machines and computers to organizations and societies.
+In general, a '''system''' is a set of interconnected elements that work together to achieve a common goal. The concept of a system can be applied to anything from machines and computers to organizations and societies.
 More formally, a system is defined as a set of interacting or interdependent component parts forming a complex or intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose or nature, and expressed in its functioning.
 == Other Definitions of System ==
-A '''System''' is an organized collection of parts (or subsystems) that are highly integrated to accomplish an overall goal. The system has various inputs, which go through certain processes to produce certain outputs, which together, accomplish the overall desired goal for the system.<ref>What is a System? [https://managementhelp.org/systems/defn-system.pdf Management Help]</ref>
+A system is a construct or collection of different elements that produce results not obtainable by the elements alone. The elements, or parts, can include people, hardware, software, facilities, policies, and documents, that is, all things required to produce systems-level results. The results include system-level qualities, properties, characteristics, functions, behavior, and performance. The value added by the system as a whole, beyond that contributed independently by the parts, is primarily created by the relationship among the parts; that is, how they have interconnected <ref>[http://www.calimar.com/TheConceptOfReferenceArchitectures.pdf How to Define a System?] </ref>
 == System Concept in Different Fields ==
-In a business setting, a system is defined as a set of procedures and components that work together to complete a task. For example, the human resources system in a company may be responsible for hiring new employees, managing employee records, and administering payroll.
+In information technology, a system is a group of components that work together to complete a task. For example, a computer system consists of hardware, software, and data storage devices working together to process information.
-In information technology, a system is a group of components that work together to complete a task. For example, a computer system consists of hardware, software, and data storage devices that all work together to process information.
+In science, a system is defined as a group of interacting elements that form a complex whole. For example, the solar system comprises planets, moons, asteroids, and comets that all interact with each other to create the conditions necessary for life.

+In social science, a system is a group of people or things that interact with each other to achieve a common goal. For example, the education system comprises schools, teachers, students, and parents who all work together to provide children with the knowledge and skills they need to succeed.

For example, the education system is made up of schools, teachers, students, and parents who all work together to provide children with the knowledge and skills they need to succeed in life.
+The concept of a system in governance is used in various ways. For example, the term "systems thinking" is used to describe an approach to problem-solving that takes into account the interrelationships between different elements of a system. In the business world, the term "systems analysis" describes the process of understanding how a business works and identifying ways to improve its performance.
 == Role: How to Use the System Concept? ==
-The concept of a system is used in situations where there is a need to study the behavior of a complex whole. The system concept can be applied to anything from a simple machine to a society.
+The system concept must not be applied when studying the behavior of a single individual or when studying the behavior of a group of individuals who are not interacting with each other.
 == Importance: Why use the System Concept? ==
 The concept of a system is important because it helps us to understand how things such as organizations work. By understanding the components of a system and how they interact with each other, we can develop ways to improve the performance of the system as a whole.

 The other benefits of the concept of a system are the following:
-- It can help us to understand the behavior of a system as a whole, rather than just the behavior of its individual parts.
+*It can help us to understand the behavior of a system as a whole rather than just the behavior of its individual parts.

 The main criticism of the system concept is that it is too abstract and that it does not take into account the individual behavior of the people who make up the system. Here are some other pitfalls in using this concept:
-*The system concept is too abstract and does not take into account the individual behavior of the people who make up the system.
+*The system concept is too abstract and does not consider the individual behavior of the people who make up the system.
 *The system concept does not allow for change or evolution.
 *The system concept is too static and does not allow for change or evolution.
 *It can be difficult to identify all of the parts of a system and their interactions.
-*It can be difficult to understand how a change to one part of a system will affect the other parts.
+*It can be difficult to understand how a change to one part of a system will affect the others.
 *It can be difficult to design a system that meets all of the requirements of its users.
