Answer :
Answer: Groupthink
Explanation: Groupthink is a way of making decisions where those decisions are made as a result of group thinking on a given topic, and thus arrive at a decision or solution that tends to seek some compromise and harmony within the group rather than some truly quality and challenging solution. It is, in fact, the psychological tendency of the group members towards the consent of all, where the usual solution is non-functional and often irrational.
That is why every time, in this case, the employee offers some solution for promotion of the advertising of the company, the proposal is ignored by the advertising team because that proposal differs from the plan which the boss has outlined in advance. So, in order for the advertising team to remain aligned with the boss, every other proposal that is even better in some parts is rejected for the sake of compromise.
