3.4 Transaction processing system (TPS)
A TPS records all the daily transactions of the organisation and
summarises them so they can be reported on a routine basis.
Transaction processing systems are used mainly by operational managers to make
basic decisions.
3.5 Management information systems (MIS)
Management information systems convert data from TPS into
information for tactical managers. This information will be designed to
help them monitor performance, maintain co-ordination and provide
background information about the organisation’s operations.
3.6 Decision support systems (DSS)
A DSS is a computer system that helps decision-makers deal with
semi- or unstructured decisions, where there is a high degree of
uncertainty, or unknown factors that may affect the decision.
A DSS will be tailor-made to the requirements of the organisation.
3.7 Executive information systems (EIS)
EIS systems provide strategic managers with flexible access to
information from the entire business, as well as relevant information
from the external environment.
The EIS enables senior management to easily model the entire business by turning
its data into useful, summarised reports. This information can then easily be
distributed to key staff members.
3.8 Expert systems (ES)
Expert systems hold specialist (expert) knowledge and allow non-
experts to interrogate the system for information, advice and
recommend decisions.
