Unit 13: Control Techniques

Notes

Did u know? According to Philip Kotler “A marketing information system consists of
people, equipment, and procedures to gather, sort, analyze, evaluate, and
distribute needed, timely, and accurate information to marketing decision-
makers.”

The terms MIS and information system are often confused. Information systems include systems
that are not intended for decision-making. The area of study called MIS is sometimes referred
to, in a restrictive sense, as information technology management. That area of study should
not be confused with computer science. IT service management is a practitioner-focused discipline.
MIS has also some differences with ERP which incorporates elements that are not necessarily
focused on decision support.
The successful MIS must support a business’s Five Year Plan or its equivalent. It must provide
for reports based upon performance analysis in areas critical to that plan, with feedback loops
that allow for titivation of every aspect of the business, including recruitment and training
regimens. In effect, MIS must not only indicate how things are going, but why they are not
going as well as planned where that is the case. These reports would include performance
relative to cost centers and projects that drive profit or loss, and do so in such a way that
identifies individual accountability, and in virtual real-time.
Anytime a business is looking at implementing a new business system it is very important to
use a system development method such as system development life cycle. The lifecycle includes
analysis, requirements, design, development, testing and implementation.

Task Explain some extra functions, characteristics, advantages and disadvantages of
the Management Information System (MIS).

Types of Information Management Systems

There are many types of information management systems in the market that provide a widerange
of benefits for companies.
• Transaction processing systems (TPS) collect and record the routine transactions of an
organization. Examples of such systems are sales order entry, hotel reservations, payroll,
employee record keeping, and shipping.
• Management information systems (MIS) produce fixed, regularly scheduled reports based
on data extracted and summarized from the firm’s underlying transaction processing
systems (TPS) to middle and operational level managers to provide answers to structured
and semi-structured decision problems.
• Decision-support systems (DSS) are computer program applications used by middle
management to compile information from a wide range of sources to solve problems and
make decisions.
• Executive support systems (ESS) is a reporting tool that provides quick access to summarized
reports coming from all company levels and departments such as accounting, human
resources and operations.
