Step 1: Recall Tuckman's Model of Group Development.
Tuckman's model outlines the stages that groups typically go through as they develop from a collection of individuals into a cohesive team.
Step 2: Identify the original four stages of Tuckman's Model (1965).
The initial model proposed four sequential stages:
a. Forming
b. Storming
c. Norming
d. Performing
Step 3: Identify the fifth stage added later (1977).
Tuckman, along with Mary Ann Jensen, later added a fifth stage to the model:
e. Adjourning (sometimes referred to as Mourning)
Step 4: Compare the given options with the stages of Tuckman's Model.
(1) Forming: This is the initial stage where the group comes together.
(2) Storming: This stage involves conflict and disagreement among group members.
(3) Performing: This is the stage where the group is cohesive and works effectively towards its goals.
(4) Stabilizing: This term is not part of the recognized stages in Tuckman's Model of group development. While the 'Norming' stage involves establishing stability and cohesion, 'Stabilizing' is not a formal stage in the model.
Step 5: Determine which option is NOT a stage in Tuckman's Model.
Based on the comparison, 'Stabilizing' is not a stage in Tuckman's Model.
