Main difference between a group and a team

Main difference between a group and a team:


Factors influencing group or team performance

Factors Influencing Group or Team Performance

  • Cohesiveness

  • Group Composition

  • Norms

  • Deviancy

  • Size

  • Social Loafing



  • Cohesiveness-extent to which members of a group like each other and want to remain members of the groups


  • Sources

    • Small size - match between group composition and nature of the task.

    • Shared success in meeting goals

    • Group maturity

  • Consequences

    • Satisfaction with the group

    • Communication

    • Hostility and aggression toward non-group members

    • Productivity

      • Contingent upon compatibility of group and organizational goals

      • Minimizes performance differences between group members

NORMS - Informal rules of behavior that provide some

order to group activities.



-Informal seating arrangements


ENFORCEMENT OF NORMS - this will happen if:

-They facilitate group success or ensure group survival

-They simplify (or make predictable) what behavior

is expected of group members

-They reinforce specific member’s roles within a group

-They help the group avoid embarrassing

interpersonal problems

Group cohesiveness performance norms and productivity

Group Cohesiveness, Performance Norms, and Productivity









Group productivity

Group Productivity


- Refers to behaviors that other members

of the group consider threatening,

embarrassing, or irritating enough

that they bring special sanctions to bear

against the person.

A deviant in the group can

A Deviantin the group can:

facilitate appreciation of the fresh perspective from new members

force the group to test the usefulness and ultimate validity of its norms

provide new and different ideas

detract from productivity due to process losses

How group size effects performance

How group size effects performance

  • Large groups have more resources available, they can complete more relatively independent tasks than small groups

  • Large groups tend to from subgroups

    • helpful if the task can be subdivided

  • Large groups tend to produce more than smaller groups (depending on the task)

  • Large groups show more tension release and giving of information than in smaller groups

More group size

More group size

  • Interactions and communication patterns tend to be more formalized in large groups

  • Large groups may be less efficient than smaller groups

  • Smaller groups report greater satisfaction

  • Importance of getting along is inversely related to size

  • Actual performance = Potential Performance less Process Losses

Stages of group team development

Stages of Group & Team Development

1. Mutual Acceptance – getting to know one another, defining purpose, leadership, structure

2. Communication and Decision Making – open discussion of opinions and ideas. Members starts to develop norms of behavior, agreement is reached on goals and often roles

Team advice for creativity

Team Advice for Creativity

  • Allow enough time

    • Stress from time constraints limit creativity

  • Avoid evaluation apprehension

    • Feeling like one is constantly being judged stifles idea generation

  • Avoid groupthink

    • Tendency of highly cohesive groups to value consensus at the price of decision quality

Use brainstorming

Use Brainstorming

Four simple rules can encourage divergent thinking while minimizing evaluation apprehension.

Rules of brainstorming

Rules of Brainstorming

  • No criticism

    • Without criticism, team members might be willing to suggest wild solutions or ideas

  • Provide as many ideas as possible

    • Quality increases with the number of ideas presented


  • Speak freely

    • Welcome wily and silly ideas since they can become the basis of divergent thinking

  • Build on ideas of others

    • Members should combine and improve on the ideas already presented – use team synergy
