Who is considered a gatekeeper in a decision-making unit?

In a decision-making unit, a gatekeeper plays a crucial role in managing the flow of information that reaches the decision-makers. This member is typically responsible for filtering, controlling, and determining which information is necessary for the evaluation of options or proposals. By intervening in communications, gatekeepers ensure that only relevant and essential information influences the decision-making process. This is particularly important in complex organizational structures where multiple stakeholders are involved.

Other roles, such as those involved in marketing strategy, financial oversight, or customer interaction, do not specifically define the function of a gatekeeper. While these members contribute to the decision-making unit, they do not focus on controlling or directing the information flow. Thus, the distinctive characteristic of the gatekeeper is their influence over what information reaches prominent decision-makers, making option B the accurate choice in this context.
