The Security Life Insurance Company processes all new life insurance policies through three departments: incoming mail (I), underwriting (U), and policy control (P). The incoming mail department receives applications and customer payments and then routes the files to the underwriting department. After checking on the applicants' qualifications for life insurance, the underwriting department forwards the file to policy control for the issue of the policy. At the present time, the company has five new policy applications waiting to be processed. The time required for processing in each department is shown below.
