A company sells consumer products like soaps and detergents using door-to-door sales. That is, salesmen make calls at homes, demonstrate their products, sell and collect payment on the spot. As the manager of the company, you are wondering the best way to assess the performance of the salesmen. That is, how to assess, what to assess, when to assess, who should be involved in the rating, etc. Discuss how you would implement a performance appraisal system for the outside salespeople in terms of the above challenges?
