Custоmer Suppоrt аt Virtuаl Cоаch Virtual Coach is an on-line personal training service that allows athletes to upload their training data (heart-rate, watts, perceived exertion, speed, etc.) and then provides personalized training plans. To support the service, they operate a small call center that receives an average of 50 calls per hour. Of these 50 calls, 45 are STANDARD and 5 are NEW USER. STANDARD calls have to do with mainly login issues or minor technical questions and take 2 minutes to answer. NEW USER calls require an agent to walk the person through the use of the software, and they take 23 minutes to answer. The coefficient of variation of call inter-arrival time is equal to 1 for both the STANDARD and the NEW USER calls. Also, there is little variation among both STANDARD calls and among NEW USER calls: the st. deviation of the time required for an agent to speak with a STANDARD or a NEW USER caller is effectively 0. Virtual Coach estimates that it costs about $0.75 for every minute that a STANDARD caller has to wait. On the other hand, because a NEW USER may be more likely to quit using the service if they have to wait, they estimate that it costs about $1.5 for every minute that a NEW USER has to wait. Currently, Virtual Coach has two employees dedicated to serving calls from STANDARD callers and 3 employees dedicated to answering calls from NEW USERS. Each type of call has its own queue. On average, how many minutes does a STANDARD caller have to wait to talk to an agent (minutes)?
