Better decisions = better managers

The amount of information people must understand to make decisions, solve problems, and find opportunities is growing exponentially

PROGRAMMED VERSUS NONPROGRAMMED DECISIONS

Programmed decisions Decisions made using a rule, procedure, or quantitative method Easy to computerize using traditional information systems

Non-programmed decisions Decision that deals with unusual or exceptional situations Not easily quantifiable

TYPES OF DECISIONS

• Structured– How many workers to staff

line A– What is the EOQ for raw

material Z– How many turbines to power

Lethbridge?

• Unstructured– What are the benefits of

merging with XYZ – How will consumer react if

we lower the price by 10%– What are the benefits of

SYSTEM DESCRIPTION: TRANSACTION PROCESSING SYSTEMS

TPSs are designed to process business events and transactions

Architecture Components• Source Documents• Data Entry Methods

• Manual – • Semiautomated –(e.g. a barcode scanner)• Fully Automated – (e.g. automatic orders from inventory

systems)

• Processing• Online• Batch –

SYSTEM DESCRIPTION: MANAGEMENT INFORMATION SYSTEMS

MISs are used by managerial employees to support recurring decision making in managing a function or the entire business

Supported Activities• Scheduled Reporting - produced automatically based on a

predetermined schedule. Some include:• Key Indicator – e.g. Monthly Sales Report• Exception – e.g. Monthly Late Shipments• Drill Down – printed only if needed

• Ad Hoc Reporting – unscheduled reports (e.g. sales data by person report to identify issues)

DECISION SUPPORT SYSTEMS

Decision Support Systemssystems designed to support managerial-level employees in organizational decision making

System Details use computational software to construct models for analysis (most common is MS Excel) to solve semi-structured problems (e.g. sales or resource forecasts)

Supported Activities: “What-if” analysis – changing one or more variables in the model to observe the effect (e.g. What is the payment if the interest rate increases by 1% ?)

EXPERT SYSTEMS

Expert Systemsused by operational level employees to make decisions usually made by more experienced employees or an expert in the field

System Details use inference engines that match facts and rules, sequence questions for the user, draw a conclusion, and present a recommendation to the user

Supported Activities:These systems support many activities, including:

• Medical Diagnosis• Machine Configuration• Financial Planning• Software Application Assistance (help wizards)

OFFICE AUTOMATION SYSTEMS

Office Automation Systemsincrease productivity within the office setting

Supported Activities• Scheduling Resources

Examples: electronic calendars• Document Preparation

Examples: software (word processing and desktop publishing); hardware (printers)

• CommunicatingExamples: e-mail, voice mail, videoconferencing and groupware

6-25

COLLABORATIVE TECHS (GROUPWARE)

Groupwareenables people to work together more effectively

Supported Activities

These systems come in two types:• Asynchronous Groupware – Systems that do not require

users to be on the system working at the same time, including: e-mail, newsgroups, workflow automation, group calendars, and collaborative writing tools

• Synchronous Groupware – Systems that allow and support simultaneous group interactions including shared whiteboards, electronic meeting support systems, video communication systems
