Choose the correct answer from the options given below :  

Key Points 

Tuckman's linear model of group development

• Tuckman's model explains that as the team develops maturity and ability, relationships establish, and leadership style changes to more collaborative or shared leadership.
• It goes through 5 stages commonly known as: 
  • Forming, Storming, Norming, Performing, and Adjourning.

Cyclical theory of group development:

• An important cyclical model of group development was proposed by behavioral scientist Connie Gersicks.
• She applied the concept of punctuated equilibrium to organizational change and group formation. 
• Gersick theorized that group development is similarly characterized by periods of punctuated-equilibrium.
• The Punctuated-Equilibrium Model (PEM), developed by Connie Gersick similar to alternate theory of evolution from Darwin’s popular evolutionary theory, this evolutionary theory suggests that the human species developed as a result of periods of punctuated-equilibrium.

Pendular perspective theory.

• In this theory, Worchel believed the main theme or pattern that is constantly repeated is that firstly conflict occurs, followed by the team resolving this issue and finally the cohesion after this resolution.
• It assumes that teams do not develop in progressive stages-Team development swings back and forth through series of conflicts and resolutions.
• Periods of conflict cause differentiation (cliques form, individuals are singled out through rewards or punishment, etc.)

Therefore we can say that the correct answer is  A, B and C only
