When an information system is being developed, much importance should be given to the structure of the organization, culture of the organization, etc. But along with these, especial attention should also be given to the technical side of MIS. The various contemporary approaches to MIS development can be summarized as:
The Socio Technical Approach
Information systems are socio-technical systems. Although they are composed of machines, devices, and “hard” physical technology, they require substantial social, organizational, and intellectual investments to make them work properly. Since problems with information systems and their solutions are rarely all technical or behavioral, a multidisciplinary approach is needed.
a) In the beginning, this approach was finding it hard to survive but now it is being accepted worldwide and is also being implemented at a very large scale.
b) Involves key involvement of both of the above explained approaches.
c) Improves the performance of the information system as a whole.
The Behavioral Approach
a) Based on the impact of the behavior and also on the response of the people in the organization.
b) Motivational Feasibility forms a very important and demanding part of such an approach towards MIS development.
The Technical Approach
- Theories of computability
- Methods of computation
- Methods of efficient data storage and access
- Models for decision making
- Management practices
- Mathematical techniques for optimizing selected parameters of organisations, such as transportation, inventory control, etc.
a) Based on the mathematical and the normative models.
b) Physical technology forms the back bone of such an approach.
c) Such an approach mainly finds much needed contributions from the disciplines like computer science, management science, operations research etc.
Porter Millar postulates
Porter and Millar were the ones, who explained the affect of the information technology on the competition. According to them information technology is affecting competition in the following ways:
a) Causes changes in the structure of the industry and as a result of this, rule of competitions is altered.
b) Spawning of the whole new business takes place, and in much of the cases – it is caused from within the company’s existing operations.
c) Competitive advantage is created usually because of the new ways; the companies get to outperform their rivals.
