Contextualise information management in terms of the decision making process

Computer based Information systems play a major role in the operations, management and strategic success of organisations. Information systems transfer data from the organisations internal and external environments into information that can be used in decision making.


Importance of managing information for sustaining competitive advantage

Competitive advantage is the ability of an organisation to provide greater value to customers than its competitors. Sustainable competitive advantage occurs when other organisations tried unsuccessfully to duplicate an organisations competitive advantage.

3 Questions need to be addressed in order to sustain a competitive advantage through information technology:

1st Does using IT lower costs and provide a better p/s?

2nd: Is the IT the same or different among competing organisations?

3rd: Is it difficult for another organisation to create or acquire the IT used by the organisation.


Explain the basic functioning of an Information System

An IS uses resources of hardware, software and people to perform input, processing, output, storage and control activities that transform data resources into information products.

Data collected for processing, then converted into information, stored for future use, or communicated to the ultimate user, according to the correct processing procedures.
