1. TPS
(Transaction Processing System).
The transaction processing
system records the data from everyday operations throughout every division or
department in the organization. Each division or department is tied together
through the TPS to provide useful information to management levels throughout
the company. It used by Supervisior (lower/operational manager) to monitor
operational everyday.
2. MIS
(Management Information System).
MIS is an integrated collection of people, procedures,
databases and devices that provides managers and decision makers with
information to help achieve organizational goals. The function of MIS is to
help an organization achieve its goal by proving manager with information. MIS
take the data and make decision to get reports (output) like summary, demand,
periodic. It used by middle manager (tactical Decision).
3. DSS
(Decision Support System).
An organized collection of people, procedures,
software, databases and devices used to support problem-specific decision making. It is used for complex
"what-if" questions that require internal and external data.
Decisions at this management level are mostly complex. Same like MIS, DSS
systems are used by middle manager (tactical) to solve specific problems in
organization.
4. ESS
(Expert Support System).
An Executive Support System (ESS) is software that
allows users to transform enterprise data into quickly accessible and
executive-level reports, such as those used by billing, accounting and staffing
departments. An ESS enhances decision making for executives.
Sharing the same concepts of a DSS, an ESS focuses
more in the end-user requirements of maximum interactivity and
user-friendlyness. An ESS can be understood as a friendly, fully customised and
interactive DSS to be mostly used by top executives and policy-makers to get
permanent and updated assessment in relation to key questions (information and
knowledge).
While a complete DSS will have efficient links to external large databases and advanced models, an ESS focuses only on interactive
and executive assessment tools, those which can be used personally by
end-users. An ESS requires a previous expert work filtering information and
knowledge into meaningful indicators and tools.
