Leading Problem Solving Groups
• How Well Did Your Group Do?– Better than the best individual score– Better than the average individual score– Better that the lowest individual score
– Type of Problem–has a known solution that can checked.

Explaining Group ProductivitySteiner’s Model
• Actual Performance = Potential Performance – Loss Due To Faulty Process
![Page 3: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/3.jpg)
Definitions
• Actual Performance = What the group accomplishes. Defined by the task
• Potential Productivity = What the group can accomplish based on members’ skills and abilities and match with task.

• Process - steps taken by the group to accomplish the task.
• Process Loss-the extent that the actual productivity is less than the potential productivity (best individual member of the team)
• Process Gain- the extent that the actual productivity is better than the potential productivity (best individual member of the team)

Types Of Process Loss Variables
• Possible Ambient factors - mere presence of other people – Distraction - pay attention to non-problem
aspects of the situation – Cognitive Interference - statements of others
hurt/interfere with our thought processes– Evaluation Apprehension - others are a natural
audience, leads to inhibition – Communication Requirements -
elaboration/defense required in presenting ideas to others

Process Losses Due to Inadequate Problem Solving Techniques
• Inadequate matching of task demands and members skills and abilities
• Inadequate search behavior• Inadequate evaluation of ideas -
premature closure• Lack of separation of idea generation
and idea evaluation phases

Process Losses Due to Faulty Interpersonal Interaction
• Cases Based On– Personality Conflict– Lack of Trust– Negative Group Identity– Biases Assessments-Faulty First
Impressions– Lack of Contract-Goals, Norms– Unrealistic Impressions– Individualistic Behavior

Process Losses Due to Lack of Group Member Motivation
• Reasons– Low task involvement: social loafing,
free riding (Lack of Identifiability, Rewards Without Effort)
• Issue Not Important• No One Is Listening (Disingenuous
Voice)• Belief That Other Have More
Expertise

Process Loss Due To Structural Variables:Group Size
• Typically assumed to be between 5-8 members.

Impact of Increasing Team Size:
• Increases in differences in participation rates among members between high and low participators.
![Page 11: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/11.jpg)
• Increase in directive leadership
• Formalization of interaction
• Increase in propensity to loaf

• Decrease in satisfaction with the group (processes, membership)
![Page 13: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/13.jpg)
•Productivity increases at a smaller rate for each additional group member.

Social Loafing and Free Riding:Motivation Loss In Groups
The tendency for group members to exert less individual effort as the size of the group increases. Less effort found on:– Performance Task: A type of group task in which the
coordinated efforts of several people are added together to form the group’s product
• Adding performance of multiple people to compute department sales.--Cognitive Tasks: Thinking of large number of solutions to a
problem when working in a group—Brainstorming in a group
--Perceptual Tasks: Number of people watching a radar screen for hostile planes
--Problem Solving Tasks: Evaluation of a problem and generating a solution. Where to locate the new plant.

Antecedents of Social Loafing:Group Size
![Page 17: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/17.jpg)
• Free Riding—A person can receive the benefits of being in a team without exerting the effort.– A members of project group does not contribute but
receives the same grade as the other members of the team, contributions to KERA.
– On a disjunctive task-performance is determined by the best member of the team, other people free ride, example, expertise of team members well known, low expertise loaf.
– On a conjunctive task, performance is determined by the low ability or skill member, people with more expertise will reduce their effort –interdependent task
![Page 18: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/18.jpg)
Why Do People Loaf and Free Ride
• Lack of Identifiability: When people share responsibility for a task and team member efforts are pooled together into a single group solution, it may be difficult to identify the contributions of each team member. – Diffusion of responsibility (less personal
responsibility) – Rational analysis of cost of one’s effort and
potential rewards.

• Dispensability of Effort: feelings that my efforts are not important to the team, can not make a contribution—my perception or team member’s behavior
![Page 20: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/20.jpg)
Other Reasons For Self-limiting Behavior-Low Motivation: Raising The White Flag
• Compelling argument that is accepted• Meaningless decision—unimportant decision or
disingenuous (no one listening)• Lacking confidence in one’s ability to
communicate or accuracy of one judgments• Strong pressures from others to conform-not
appear like a deviant, not lose approval• Other team members appear indifferent,
unwilling to commitment themselves• Cycle of failure

Overcoming Social Loafing, Free Riding, Self Limiting Behavior
Make each team member’s contributions identifiable
Make individuals feel efforts are indispensable-personal responsibility
How do you do this? Make work tasks more
important and interesting Reward individuals for
contributing to their group’s performance
![Page 22: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/22.jpg)
Overcoming Social Loafing, Free Riding, and Self-LimitingBehavior
• Use group goal setting
• Use a contract to bind team members
• Increase cohesiveness of group—team members feel a sense of obligation
![Page 23: Leading Problem Solving Groups](https://reader030.vdocuments.site/reader030/viewer/2022033103/5681406d550346895dabeb59/html5/thumbnails/23.jpg)
• Have the task provide team members with the chance to evaluate their performance or receive some feedback against some standard.
• Increase Fairness of Decision of Making Processes
• Pay Attention to Size of the Group
• Monitor People (Accountable) and the Process (Problems)

Social Loafing and Culture
Individualistic Cultures: National groups whose members place a high value on individual accomplishments and personal success.
Collectivistic Cultures: National groups whose members place a high value on shared responsibility and the collective good of all.
