Group Decision Making

  1. 1. Group Decision Making
  2. 2. Need for group decisions  To pool diverse expertise in order to coordinate the actions of all for a common goal  Decisions made by groups are superior to the decisions made by individuals  Groups outperfom individuals
  3. 3. Decision-Making Process Define the Problem Decisions: Choices of actions from among multiple feasible Identify Criteria alternatives • Define the problem Gather and Evaluate Data – Gaps between where we are today and where we would like to be tomorrow • Identify the criteria – What information is needed in order to evaluate alternatives? • Gather and evaluate data – Collect information relevant to the criteria and potential alternatives
  4. 4. Decision-Making Process Define the Problem Decisions: Choices of actions from among multiple feasible Identify Criteria alternatives • List and evaluate alternatives Gather and Evaluate Data – Develop an complete list of possible solutions to the problem (few constraints) – Assess each alternative using List and Evaluate Alternatives each criterion from step 2 • Select best alternative – Choose the one which satisfies Select Best Alternative the criteria the best • Implement and follow up – Monitor the results Implement and Follow Up
  5. 5. Optimal versus Satisfactory Decisions  Optimal decision  The maximizing decision, yielding the absolute best result  Satisficing decision  Satisfactory rather than optimal decision  Lack capability to collect and process all of the information relevant for a particular decision  Will never know if all possible alternatives have been identified  Lack of time and other necessary resources for completing all of the decision activities  Thus, a tendency to choose the first satisfactory alternative discovered
  6. 6. Decision-Making Styles  Individual’s predispositions can affect decision process at two critical stages  Gathering (Perceiving) of information  Sensing style  Intuition style  Evaluating (Judging) of alternatives  Thinking style  Feeling style
  7. 7. Define the Problem Decision-Making Styles Identify Criteria Sensing Intuition Perceptual Influences Gather and Evaluate Data Using the five Using abstractions senses to identify and describing the Feedback factual details “big picture” Develop and Evaluate List of Thinking Feeling Perceptual Influences Alternatives Using objective Using subjective Choose Best analysis and values with emotional Alternative rational procedures and personal factors Implement and Follow Up
  8. 8. Degree of Acceptable Risk  Risk exists when the outcome of a chosen course of action is not certain  Risk-taking propensity (Willingness to take chances)  Low risk takers  May collect and evaluate more information  May become paralyzed by trying to obtain and consider too much information  High risk takers  May may decisions based on too little information  May jump to decisions too quickly
  9. 9. Why do groups make bad decision?  Information sharing biases  Risky shift phenomenon  Social loafing  Conformity
  10. 10. Team Building
  11. 11. Types of Team  Recommender Teams: those that recommend things – task forces or project groups  Doer Teams: those that make or do things – manufacturing, operations, or marketing groups  Managing Teams: those that run things – groups that oversee some significant functional activity
  12. 12. Types of Team  Recommender Teams are often part-time; great for reviewing work but can lack a “team engine” for getting detailed work done  Managing Teams are often staffed with senior executives who have serious time management challenges and are unlikely to engage with traditional team communication  Doer teams are great for doing things but their networks may be limited to their own functional areas which can blind them to some innovation and cross-functional opportunities
  13. 13. Types of Team  Task Force - a temporary team assembled to investigate a specific issue or problem  Problem Solving Team - a temporary team assembled to solve a specific problem  Product Design Team - a temporary team assembled to design a new product or service  Committee - a temporary or permanent group of people assembled to act upon some matter
  14. 14. Types of Team  Work Group - a permanent group of workers who receive direction from a designated leader  Work Team (Self-Directed Work Team) - an ongoing group of workers who share a common mission who collectively manage their own affairs within predetermined boundaries  Quality Circle - a group of workers from the same functional area who meet regularly to uncover and solve work-related problems and seek work improvement opportunities
  15. 15. Stages of Team Development
  17. 17. Forming Stage Becoming Acquainted and Organized
  18. 18. Forming Stage Feelings of . . .  Excitement  Suspicion  Fear  Anticipation  Optimism  Anxiety
  19. 19. Storming Stage Clarifying project needs and goals
  20. 20. Storming Stage Feelings of . . .  Resistance to the task  Uncertainty about the team’s success  Impatience  Hostility  Discomfort
  21. 21. Norming Stage Determining solution methods
  22. 22. Norming Stage Feelings of . . .  Safety and security  Acceptance  Relief  Renewed Energy
  23. 23. Performing Stage Implementing the project
  24. 24. Performing Stage Feelings of . . .  Satisfaction  Pride  Excitement
  25. 25. Adjourning Feelings of . . .  Satisfaction  Completion  Excitement  Sadness
  26. 26. Team Development Stages
  27. 27. Team Effectiveness

  30. 30. Effective Individual Productivity Team Personal Innovation Follow up Self Measurement Discipline Critical Personal Events Conduct Momentum Atmosphere Coordination Synergy Team Productivity
  31. 31. Punctuated Equilibrium Model  Explains temporary group with deadlines. These temporary groups go through transitions between inertia and activity
  32. 32. Punctuated Equilibrium Model
  33. 33. Sequence of Actions 1. Setting group direction 2. First phase of inertia 3. Half-way point transition 4. Major changes 5. Second phase of inertia 6. Accelerated activities
  34. 34. Requirements  Common purpose or goals or objectives  Awareness of membership and commitment  Common operating norms  A need for each other/interdependence  Accountability to a higher level
