Which role is responsible for supervising the estimator and parts personnel within an automotive repair shop?

The role responsible for supervising the estimator and parts personnel within an automotive repair shop is the shop foreman. The shop foreman is typically in charge of overseeing the daily operations of the shop, including managing the technicians, estimators, and parts staff. They ensure that all work is progressing efficiently and to standard quality levels, making critical decisions regarding workflow and resource allocation. This role requires a combination of technical knowledge and leadership skills, as the foreman must coordinate the efforts of various team members to deliver successful repair outcomes.

In contrast, while the service writer interacts with customers regarding repair orders and estimates, they do not typically supervise staff. The parts manager focuses on inventory and procurement of parts rather than overseeing repair shop personnel. The office manager handles administrative tasks and may not directly supervise technical staff such as estimators or parts personnel. Thus, the shop foreman is the appropriate choice for this supervisory role within an auto repair setting.
