A medical clinic has two administrators handling all processing of insurance claims in a shared office. Administrator A handles only private insurance claims and processing. Administrator B handles only Medicare claims. On average, it takes about the same time (15 minutes) to process private or Medicare claims. Medicare patients arrive at the counter at a rate of three per hour, while private insurance patients arrive at a rate of two per hour. Use the Single Server Queue or Multiple Server Queue Excel templates as appropriate to answer the following questions:

a. What is the average waiting time for each type of patient (claim) given the current job design?

b. What is the average waiting time for both types of patients if each administrator could handle either transaction?

c. What do you recommend the medical clinic do with regard to insurance claim processing and job design?
