• Members can reduce both primary and secondary tension by sharing what they know
about the problem at hand.
• Secondary and tertiary tensions can be managed if group members demonstrate
tolerance for disagreement.
• Humor is also an effective way to handle group secondary and tertiary tension.
C. Phase Models of Group Development
Tuckman’s Model of Group Development
• Tuckman’s model of group development assumes that groups move through five
stages in order.
o Forming occurs when group members first meet. Members form initial
impressions of one another, start to get a handle on the group’s task, and focus
on getting along.
o Storming occurs when members start to tackle the group’s important issues and
strong feelings start to surface.
o In the norming phase, the group has worked through its initial conflicts. They
learn to appreciate the skills and abilities of their fellow group members and
begin to feel that they are part of a group.
o During the performing phase, group members are able to work smoothly and
effectively. However, not all groups reach this phase. For groups that do reach
this stage, members become interdependent, responsibilities shift appropriately,
and group identification is high.
o The adjourning phase is where the group completes its task and the group
members prepare the group to disband.
Gersick’s Two-Phase Model
• Gersick’s two-phase model explains the patterns, which are often non-linear, that
groups exhibit as they move through their phases (e.g., back and forth between stasis
change).
o Regardless of how long a group has to complete its task major, changes will
occur at the midpoint in the group’s life.
o Prior to the midpoint, the groups identify the charge and how they would
approach the task.
o At the halfway point, the groups realize that their time is beginning to run out.
Members then break from their routine work to assess their progress toward the
group’s task.
