Question

Compare and contrast the following different approches of systems thinking. Hard Systems, Systems Dynamics, Organizational Cybernetics, Complexity Theory, SAST, Interactive planning, SSM, TSI, and CST.

Answer 1

System thinking is a way of approach by which different components of a system will act differently in other systems.this is one of the modern new approach.

There are different approaches in system thinking

They are

1.Hard systems

There are two types of systems that is hard system and soft system .in the hard system it is assumed that the problem will have only one definition solution. But in the case of soft system it is assumed that the problem is complex. So the hard system approach is one of the main in system thinking

2.system dynamic

System dynamic is another approach in system thinking and this is based on computer aided design.examples of system dynamics of population growth ,study of the celestial bodies etc.

3.organisational cybernetics

Organisational cybernetics is another approach in system thinking and this is purely based on communication principles .examples of organizational cybernetics are human brain ,electronic computer etc

4. Complexity theory

Complexity theory is another approach of system thinking in which in this theory it determines how complex is a problem with the help of Turing machines .mainly in this approach two types of complexities are taken into account they are time complexity as well as space complexity.

5.SAST

Static application security testing or SAST is a white box testing this type of testing mainly test the source code , bytecode etc.

6. Interactive planning

Interactive planning is another approach for system thinking. This type of approach mainly combines all the stakeholders for a discussion. In this type of approach everyone will get a chance to present their views and work according to that.

7.SSM,TSI,CST

SSM is soft system methodology in which it assumes that solution to a problem is not definite . This is also one of the approach in system thinking.

TSI is total system intervention is a new method in system thinking.

CST is critical system thinking is related to the philosophy.
