STAGES OF GROUP DEVELOPMENT
Mutual acceptance stage of group development is characterized by
members sharing information about themselves and getting to know each other.
Communication and Decision Making Members discuss their feelings more openly and
agree on group goals and individual roles in the group
![Page 8: Phase One Type of GroupGroup Formation Phase Two Group Development stages Mutual Acceptance Communication and Decision Making Motivation and Productivity](https://reader035.vdocuments.net/reader035/viewer/2022071806/56649da95503460f94a9601b/html5/thumbnails/8.jpg)
Motivation and Productivity Members cooperate, help each other and work
toward task accomplishment
Control and organization Members work together and are flexible,
adaptive, and self-correcting

GROUP PERFORMANCE FACTORS
Group performance factors including; Composition Size Norms Cohesiveness
They affect the success of the group in fulfilling its goal

Group Composition Degree of similarity or differences in the characteristics of the
members on factors important to the group’s work.

A homogeneous group is more useful for :
A heterogeneous group is more useful for:
• Simple tasks• Sequential tasks• Cooperation required• Speed required
• Complex tasks• Collective tasks• Creativity required• Speed not important

Group size Number of members of the group and affects the number of
resources available to perform the task
Group norm Standard against which the appropriateness of a behavior is
measured
i. Norms help the group survive
ii. Norms simplify and make more predictable the behaviors expected of group members
iii. Norms help the group avoid embarrassing situations
iv. Norms express the central values of the group and identify the group to others

Group CohesivenessFactors that affect group cohesiveness
and consequences of group cohesivenessFactors that affect group cohesiveness
Consequences of high cohesiveness
• Homogeneous composition• Mature development• relatively small size• Frequent interactions•Clear goals (competition or external threat)• Success
• goal accomplishment • personal satisfaction of members• increased quantity and quality of interactions• groupthink
![Page 13: Phase One Type of GroupGroup Formation Phase Two Group Development stages Mutual Acceptance Communication and Decision Making Motivation and Productivity](https://reader035.vdocuments.net/reader035/viewer/2022071806/56649da95503460f94a9601b/html5/thumbnails/13.jpg)
Factors that decrease cohesiveness
Consequences of low cohesiveness
• Heterogeneous composition• Recent formation• Large size• Physical Dispersion • Ambiguous Goals• Failure
• Difficulty in achieving goals • increased likelihood of disbanding • Fewer interactions •Individual orientation

GROUP DECISION MAKING
Group Polarization Tendency for a group’s average post-discussion attitudes to
be more extreme than its average pre-discussion attitudes.
Groupthink Mode of thinking that occurs when members of a group are
deeply involved in a cohesive in group and desire for unanimity offsets their motivation to appraise alternative courses of action

Participation in Decision Making Important part of managing motivation, leadership, organization
structure, and decision-making processes
Group Problem Solving Brainstorming
Technique used in the alternative generative phase of decision making that assists in development of numerous alternative courses of action
Nominal Group Technique (NGT)• Group members follow a generate discussion vote cycle
until they reach an appropriate decision. The Delphi technique
• Method of systematically gathering judgments of experts for use in developing forecasts

INTERGROUP DYNAMICS
Interaction among groups are based on the characteristics of the interacting groups, the organizational context within which the groups operate, and the task and situational bases of the interactions
Five factors that determine the nature of group interactions are; Location Resources Time and goal interdependence Task uncertainty Task interdependence
