Systems Concepts introduction
This Systems Concepts unit introduces further concepts supporting identification and creation of systems and definition of their purpose as well as an introduction to complex systems. Concepts, terms and components are properties of all systems: Goals/Objectives Input/Ouput Feedback Control Boundary Environment Sub System Hierarchy Emergence Dynamic Equilibrium Perspective/Stakeholders Transformation If situation cannot be viewed with…

Natural systems example
Exists in nature, independent of human modification. Consists of physical and biological materials and intertwined processes. E.g. growth of plants, weather system and fertility of soil. Agriculture example of human organisational system introduced to existing natural system to control and modify it. It is affected by natural systems such as weather, ability of soil to…

Organisational systems example
Organisations have management structure determining relationships between activities performed and employees performing them. Organisations considering open systems – they affect and are affected by their environment. Many organisations were considered closed systems as they organised and operated within with no regard for their environment. Managers would analyse each department in turn which although working well individually…

Environment and Ecology systems example
Humankind has learned to live in many environments based on successful adaptation. Interaction of humans with environment (surroundings) results in major changes both good and bad. Bad changes often from making too big a change in environment. e.g. first settlers in Americas caused 50 million deaths by disease resulting in a fall of carbon dioxide…

Engineered and Physical systems example
Engineered system – man-made system to fulfil specific purpose. A combination of components working together to collectively perform useful function. E.g. new manufacturing process, technology to improve delivery of a service, an infrastructure system.

Feedback Loops
Feedback helps control a system in either a good way or a bad way. Inappropriate feedback can lead to erratic behaviour or even collapse of the system. Always try to provide feedback based on desired output. Can be either direct or indirect (from another system). Feedback loops enhance, decrease or buffer changes within system. Feedback…

The Black Box Approach
Black box concept – what happens inside not of initial interest. Input(s) and output(s) are of concern. Box represents a process. Initial idea can be developed further by breaking down into further sub-systems with their own inputs & outputs. Easy to go wrong with complex systems if deductive logic not followed.
