How could Jack use the job characteristics model to redesign the job of salespeople in the store?

Jack Deppster arrived for his first day of work as store manager at Buzz, one of the largest and most popular retail stores at a local mall. Buzz, operating various locations throughout Canada, sold clothing and accessories targeted to people between 18 and 24 years old. Jack, who had a business administration degree, was seen as a motivated and self-directed person who got results. On the basis of his strong GPA, volunteer experience, and previous retail experience working as a salesperson for a grocery store, the management group at Buzz expected a strong performance from him. Jack impressed the HR hiring manager and district manager during the interview process, and they believed he would have no problem in achieving the target of increasing store sales by 5% over the next 6 months. Jack also believed he could achieve this goal and was excited about the opportunity to take on his first management role.
