Principles and Learning Objectives
• Good decision-making and problem-solving skills are the key to developing effective information and decision support systems.
• The management information system (MIS) must provide the right information to the right person in the right fashion at the right time.
• Decision support systems (DSSs) are used when the problems are unstructured.
• Specialized support systems, such as group support systems (GSSs) and executive support systems (ESSs), use the overall approach of a DSS in situations such as group and executive decision making.

Decision Making as a Component of Problem Solving
Figure 6.1: How Decision Making Relates to Problem Solving
5
Programmed Versus Nonprogrammed Decisions
• Programmed decisions– ___________ made using a rule, procedure, or
quantitative method– Easy to computerize using traditional information
systems• Non- ___________ decisions
– Decision that deals with unusual or exceptional situations
– Not easily quantifiable
6
• Programmed– How many workers to staff
line A– What is the EOQ for raw
material Z– How many turbines to
power Lethbridge?
• Non-Programmed– What are the benefits of
merging with XYZ – How will consumer react if
we lower the price by 10%– What are the benefits of
MacDonald's opening up Hotels
7
Optimization, Satisficing, and Heuristic Approaches
• ___________ model: a process that finds the best solution, usually the one that will best help the organization meet its goals
• ___________ model: a process that finds a good—but not necessarily the best—problem solution
• Heuristics: commonly accepted guidelines or procedures that usually find a good solution
8
Management Information Systems in Perspective
• A management information system (MIS) provides managers with information that supports effective decision making and provides feedback on daily operations
• The use of MISs spans all levels of management

Inputs to a Management Information System
• Internal data sources– TPSs and ERP ___________ and related databases;
data warehouses and data marts; specific functional areas throughout the firm
• External data sources– Customers, ___________ , competitors, and
stockholders, whose data is not already captured by the TPS; the Internet; extranets
11
Outputs of a Management Information System
• ___________ report: produced periodically, or on a schedule
• Key-indicator report: summary of the previous day’s critical activities
• Demand report: developed to give certain information at someone’s request
• ___________ report: automatically produced when a situation is unusual or requires management action
• Drill-down ___________ : provides increasingly detailed data about a situation
12
Functional Aspects of the MIS
• Most organizations are structured along functional lines or areas
• The MIS can be divided along functional lines to produce reports tailored to individual functions
13
Functional Aspects of the MIS (continued)

integrated collection of
functional information
systems, each supporting
particular functional areas.

Other Management Information Systems
• ___________ MIS: provides aggregate information on accounts payable, accounts receivable, payroll, and many other applications
• ___________ information system (GIS): capable of assembling, storing, manipulating, and displaying geographic information– Customer Analysis – Market Analysis – Site Selection – Risk Analysis – Territory Management – Facility/Property/Asset Management – Supply Chain Management – Logistics
19
An Overview of Decision Support Systems
• A DSS is an ___________ collection of people, procedures, software, databases, and devices used to support problem-specific decision making and problem solving
• The focus of a DSS is on decision-making ___________ when faced with unstructured or semistructured business problems
20
Capabilities of a Decision Support System
• Support all problem-solving phases
• Support different decision frequencies– One of kind to continuous
• Support different problem structures– Structured to no structured
• Support various decision-making levels – All levels of decision making
• Pres-Dean-Prof

Group Support Systems
• Group support system (GSS)– Consists of most ___________ in a DSS, plus
software to provide effective support in group decision making
– Also called group decision support system or computerized collaborative work system

26
Characteristics of a GSS That Enhance Decision Making
• Special design
• Ease of use
• Flexibility
• Decision-making support
• Anonymous input
• Reduction of negative group behavior
• Parallel communication
• Automated record keeping
27
GSS Software
• Often called groupware or workgroup software
• Helps with joint workgroup scheduling, communication, and management
• Examples: Lotus Notes, Microsoft’s NetMeeting, Microsoft Exchange, NetDocuments Enterprise, Collabra Share, OpenMind, TeamWare
• Some transaction processing and enterprise resource planning packages include collaboration software
