Information Systems in Organizations Computer-based information systems (CBIS): makes use of computer  hardware and software, databases, telecommunications, people, and  procedures to manage and distribute digital information Types of Information Systems: Decision support system (DSS): an information system used to support  problem-specific decision making o Ex: dating services match profiles o Group decision support system (GDSS): sometimes called a  computerized collaborative work system, provides tools for groups  to reach consensus and design the most effective solutions with  minimum time and effort, consists of the hardware, software,  people, databases, and procedures needed to provide effective  support in group decision-making settings Groupware: GDSS software helps with joint work group  scheduling, communication, and management.  All group  members can share info to accomplish joint work, even  when group members are located around the globe. Management information system (MIS): an information system used to  provide useful information to decision makers, usually in the form of a  report, used to support programmed decisions made in response to  structured problems o Ex: list of available classes with open seats o Primary tool for making sense out of mountains of data o Primary purpose is to help individuals and organizations achieve  their goals by providing reports and information to make better  decisions Transaction processing system (TPS): an information system used to  support and record transactions, capture and store the data resulting form  ongoing transactions o Ex: processing grades, paying bills Decision making process: process that takes place in three stages-  intelligence, design, and choice Problem solving process: includes decision making (intelligence, design,  and choice) and implementation and monitoring

o Intelligence stage: identify and define potential problems or  opportunities o Design stage: alternative solutions to the problem are developed,  feasibility and implications of these are evaluated o Choice stage: requires selection a course of action o Implementation stage: action is taken to put the solution into effect o Monitoring stage: decision makers evaluate the implementation of  the solution to determine whether the anticipated results were  achieved and to modify the process in light of new information  learned during the implementation stage- feedback/adjustment Reactive problem solving: the problem solver waits until a problem  surfaces or becomes apparent before any action is taken Proactive problem solving: problem solver seeks out potential problems
