Week 8 - Organisations and Information Systems

A problem always needs a solution and different people have different view points to solve a problem.

The ingredients of a system are components, the relationship between the components, the behavior or activities of a system, its relevant environment, the input and the output and special interest of the observer.

A system is an organized assembly of components.

We went through the difference between a system and a heap.

Ackoff suggests that there are 3 steps process of analysis:

Take something apart, understand what the parts do and aggregate the understanding of the parts into understanding of the whole

Viable Systems Model (VSM) - VSM was developed by Stafford Beer. VSM has been used as a conceptual tool for understanding organisations, redesigning them and supporting the management of change. The VSM looks at a company as it is a living thing and describes how it should structure to operate most effectively in the environment.

Beer's studies led him to view human form as five interacting systems
System 1 : activities and operations of the body (muscles and organs)
System 2 : Monitoring (Nervous system monitoring the muscles and organs)
System 3 : Autonomous control (Part of the brain which oversees the entire system of muscles and organs)
System 4 : The mid brain (Scanning environment through senses, future planning and projections)
System 5 : Higher brain functions, policy decisions

Five systems of the VSM
System 1 : The entire collection of interacting operational units
System 2 : The system responsible for coordination of operational units
System 3 : Autonomous
System 4 : Intelligence
System 5 : Policy

Using information systems effectively requires an understanding of the organisation (culture, people, process & information technology shaping the systems)
An information system creates values to the firm as an organisational and management solution to challenges that are posed by the environment
