Information System Analysis and Design
Management will want to avoid the embarrassment, difficulties, and damages to the reputation that can occur if personal or other confidential data are lost or disclosed. In other words, there is a need for control over information so as to provide a good management information system. Data can only be realized if it is derived from a properly identified and responsible source.
The IRPM can put in place an organized research team to conduct research and assemble information that will be used by management to analyze both qualitative and quantitative approaches. Following the analysis, the decision reached may apply predetermined criteria in evaluating the situation and to undertake some degree of subjective evaluation of the result produced in relation to the situation.
IRPM also provides information for the design of an information system that would be characterized by the following:
- Recording transactions between particular systems and subsystems in terms of the inputs and outputs. This may be between the organization and other external systems, or internally between the organization’s various sub-systems.
- Recording or monitoring the processing activities within a system or sub-system with a view to providing information on the efficiency and effectiveness of the operations or activities involved.
- Processing the information itself as the basic resource. Examples of this would include market research and intelligence systems.
