After a year of managing his new team, Johan reviews the team's performance and discovers that, despite being treated equitably by him, sales representatives he hired from outside the company are vastly underperforming compared to sales representatives he hired from inside the company. What is a change Johan could make to help these underperforming sales representatives perform at the level of the other team members?
A) Provide incentives for high performance that are not dependent on loyalty to the company.
B) Require the sales representatives from outside the company to rotate through at least three other departments in the company before they can begin selling.
C) Add in more psychometric testing in the hiring stage to guarantee that he is only hiring sales representatives with the temperament to meet goals.
D) Ask everyone in the department to log their time in ten-minute intervals so they are held accountable for their actions.
E) Include training on the company, company culture, and product knowledge along with the training he gives incoming sales representatives on basic sales skills.
