[Buffаlо] Justin is the CEO оf White Buffаlо, а nightclub in Downtown Gainesville. He wanted to conduct an experiment to see if his staff are using outstanding customer service skills even late in the evening (or technically, early in the morning at 1 am!), which is their busiest time but also when most of their employees are exhausted and drained. Because the fee to get in the door is $20 and the place is packed every night, Justin had the funds to pay an actor, Chloe, to pretend to be a customer. Justin told the actor to try to order a beverage and observe how the employees interact with her. Jimmy and Bryce did not really perform well. However, Jordan and Evan did an outstanding job. Following this experiment, Justin decided that Jordan and Evan will each get an extra 2 days of paid vacation days for the year. What improving implementation approach did Justin use in this scenario?
