Which term describes someone who assists in making decisions but does not have decision-making power?

The term that accurately reflects someone who assists in making decisions but does not have decision-making power is "Influencer." Influencers play a crucial role in the decision-making process by providing information, expertise, and opinions that can significantly shape the perspectives of decision-makers. They often have a strong understanding of the needs and preferences of users or stakeholders, which enables them to sway decisions based on their insights and recommendations.

In many organizational settings, influencers may be subject matter experts, consultants, or other personnel whose views impact the choices made by those with the authority to approve or reject proposals. Their influence is vital because it can lead to better-informed decisions and more favorable outcomes for the organization.

While other terms like gatekeeper or end user describe different roles within the decision-making process, they do not capture the essence of someone who contributes to the decision-making dialogue without holding the ultimate power to make final choices. This distinction is what makes "Influencer" the correct option in this context.
