By fulfilling service requests, the support center enables the productivity of whom?

The correct answer, which is end users, highlights the essential role of the support center in enhancing the productivity of individuals who directly utilize products or services. By fulfilling service requests, the support center addresses specific needs or issues that end users face, allowing them to focus on their tasks without interruptions. When users receive timely support for their inquiries or problems, they can perform their roles more efficiently, contributing positively to overall organizational productivity.

Group interactions with the support center may include interactions with customers, suppliers, and management, but the primary goal of fulfilling service requests is to serve those who use the products or services day-to-day—namely, the end users. Thus, prioritizing end-users not only maintains their satisfaction but also supports the smooth functioning of the entire organization's operations.
