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.

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
5
• 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

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

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
10
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
11
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
