7.1 Functional Information Systems

Chapter 7 7“ Copyright 2005 John Wiley & Sons Inc.”`

Functional Information Systems cont…

Functional information Systems can be divided into two general categories: function-specific and function- general . The most common type of function-general system, is management information systems (MISs)

Chapter 7 8“ Copyright 2005 John Wiley & Sons Inc.”`

Management Information System (MIS)

A system that provides information to managers in the functional areas, in order to support managerial tasks of planning, organizing, and controlling operations.

Chapter 7 9“ Copyright 2005 John Wiley & Sons Inc.”`

An MIS produces routine, ad-hoc (on-demand) and exception report:

Ad-hoc ( on- demand) reports: Nonroutine reports.Drill- down report: Reports that show a greater level of detail than is included in routine reports.Key- indicator reports. Reports that summarize the performance of critical activities .Comparative reports. Reports that compare performance of different business units or time periods.Exception report. Report that include only information that exceeds certain threshold standard

Chapter 7 10“ Copyright 2005 John Wiley & Sons Inc.”`

Information systems can also be function-specific

Typical function- specific system are accounting, finance, marketing, operations (POM), and human resources management

Chapter 7 11“ Copyright 2005 John Wiley & Sons Inc.”`

Major characteristic of functional information systems

Frequently composed of smaller systemsIntegrated or independentInterfacing Supportive of different organizational levels

7.2 Transaction ProcessingInformation Systems (TPS)

Information system that supports routine, core business transactions.

Chapter 7 13“ Copyright 2005 John Wiley & Sons Inc.”`

Objectives of a TPS

To provide all the information needed by law, by management and / or by organizational policies to keep the business running properly and efficientlyto efficiently handle high volume of data,to avoid errors due to concurrent operationsto handle large variations in volume To avoid downtime, never lose results, and maintain privacy and securityTo interface with many IT applications, including e-payment, e-procurement and e-marketing.

Chapter 7 14“ Copyright 2005 John Wiley & Sons Inc.”`

Activities and Methods of TPSs

First, data are collected by people or sensors and entered into the computer via any input device. Next the system processes data in one of two basic ways: batch or online processing.Batch processing: processes data in batches at fixed periodic intervals.Online processing: processes data as soon as a transaction occurs.

Chapter 7 15“ Copyright 2005 John Wiley & Sons Inc.”`

The Major Characteristics of a TPSTypically . Large amounts of data are processed.

The source of data are mostly internal , and the outputs is intended mainly for an internal audience . This characteristic is changing somewhat, since trading partners may contribute data and may be permitted to use TPS output directly .

The TPS processes information on a regular basis: daily, weekly, biweekly and so on.

Large storage (database) capacitv is required.

High processing speed is needed due to the high volume.

The TPS monitors and collects past data

Input and output data are structured. Since the processed data are fairly stable, they are formatted in a standard fashion.

A high level of detail (raw data, not summarized) is usually observable,especially in input data but often in output as well.

Low computation complexity (simple mathematical and statistical operations) is usuallv evident in a TPS.

A high level of accuracy, data integrity, and security is needed. Sensitive issues such as privacy of personal data are strongly related to TPSs.

High reliability is required. The TPS can be viewed as the lifeblood of the organization . Interruption in the flow of TPS data can be fatal to the organization .

Inquiry processing is a must . The TPS enables users to query files and databases ( even online and in real time)
