This document describes a program called "Who Made the Sale?" which is designed to train customer service employees through a series of simulated customer service investigations. The program aims to identify which employees best understand customer needs, make customers feel at ease, provide help when needed, resolve issues when customers are unhappy, and work as a team. It focuses on applying skills on the job rather than removing employees from work for long training sessions. The program is assessed based on manager observations and participant feedback rather than exams.
