a) Characteristics of management information systems
- MIS professionals usually design MRS rather than end users- using life cycle oriented
development methodologies.
- They are large and complex in terms of the number of system interfaces with the various
users and databases.
- MRS are built for situations in which information requirements are reasonably well
known and are expected to remain relatively stable. This limits the informational
flexibility of MRS but ensures that a stable informational environment exists.
- They do not directly support the decision making process in a search for alternative
solutions to problems. Information gained through MRS is used in the decision making
process.
- They are oriented towards reporting on the past and the present, rather than projecting the
future. Can be manipulated to do predictive reporting.
- MRS have limited analytical capabilities. They are not built around elaborate models, but
rather rely on summarisation and extraction from the databases according to the given
criteria.
