This document discusses collaboration and group decision support systems (GDSS). It defines GDSS as a computer-based system that facilitates solving unstructured problems by a group. GDSS aims to support group activities, minimize process losses, and be easy to learn and use. However, GDSS may induce process and task losses if team participants have different backgrounds or if a few members dominate. Effective GDSS requires attention to participant quality and management of conflicts that can arise from differing interests or understandings among group members.
9. Groupware ? Software products that support groups of people engaged in a common task or goal Provides a mechanism to share opinions and resources Term is ambiguous Thousands of software vendors and packages
10. Groupware ? Idea Generation (Brainstorming) Managing Sessions Multi-criteria Making Products Strategic Planning Decision Planner Innovator (Meeting-Enhancement Keypad System) One Touch (Supports Remote Teaching and Conferencing)
11. Groupware ? OptionFinder (Brainstorm, weigh alternatives, identify priorities, vote, and work toward consensus in a non-decision room setting.) Coordinator (Integrated E-mail, scheduling, and calendaring) Vineyard (Repository of shared information ) Iris (Distributed, multi-user collaborative multimedia writing environment)
12. Before we continue…. Still have the gut to say that you still have no idea for your proposal ?
16. Collaborative DSS via internet ? Telecommuting ? Work at home Virtual Team ? Freelancer Project based Online office Tailor made Ready to use Cloud computing
20. Why Group DSS Most complex decisions made by groups Complexity of organizational decision making implies more need for meetings and groupwork Complex meeting preparation and activities Need for computerized support
21. GDSS ? Consists of a set of software, hardware, language components, and procedures that support a group of people engaged in a decision-related meeting An interactive computer-based system that facilitates the solution of unstructured problems by a group of decision makers
22. GDSS characteristics Specially Designed IS Goal of Supporting Groups of Decision Makers Easy to Learn and Use May be designed for one type of problem or for many organizational decisions Designed to encourage group activities Attempts to minimize process losses
23. GDSS Problem Quality team participants Different functional areas Different supervisory levels Different perspectives May induce process and task losses Domination by one or a few members Poor interpersonal communication Fear to express innovative ideas
24. Before we continue…. Pay attention to the members quality Beware of the retention Is the quality already good for all the members ?
25. How it works Meetings are a joint activity The outcome of the meeting depends on its participants. The outcome of the meeting depends on the decision-making process Differences in opinion are settled either by the leader or negotiation or arbitration
30. Why GDSS is not ideal ? High Cost Need for a Trained Facilitator Software Support for Conflict Issues, NOT Cooperative Tasks Infrequent Use Different Place / Different Time Needs May Need More Than One
31. Before we continue…. Still lack of idea of what you going to make in this course ?
33. NSS ? Conflicts among decision makers Negotiation - for Conflict Resolution Types of Disputes Negotiators' interests are fundamentally opposed Negotiators share basic objectives, differ in priorities GDSS Can Provide Structure to Negotiations
34. NSS ? Conflicts arise because of differences in interests among individuals Conflicts also arise because of differences in problem understanding (misunderstanding) Requirements Negotiation 1. Conflict Detection 2. Resolution Generation 3. Resolution Choice
35. Before we end…. GDSS using what kind of algorithm ? GDSS is easy ? GDSS or groupware ? GDSS or workflow ?
