Answer:
a. forming
Step-by-step explanation:
The forming–storming–norming–performing model of group development was first proposed by Bruce Tuckman who said that these phases are all necessary and inevitable in order for the team to grow, face up to challenges, tackle problems, find solutions, plan work, and deliver results.
Forming: The team meets and learns about the opportunities and challenges, and then agrees on goals and begins to tackle the tasks. Team members come together to become oriented to the tasks as well as to one another. They meet and deliberate on defining the scope of the task, how to approach it, and similar concerns. How to move from this stage to the next, each member must relinquish the comfort of non-threatening topics and risk the possibility of conflict.
