As you know, we have been analyzing the customer service data that each of you has compiled and submitted to me. What we have found from an analysis of the data is that service times seem to be dependent on two things:

1. Whether the order is placed from the breakfast menu in the morning or from the lunch menu during the day
2. Whether the order is placed at the counter or at the drive through

The attached data file contains the service times from your restaurant and has been reworked to reflect these venues (a venue is a combination of a menu type and a location for the order). We need a detailed description of the service times in each venue. Analyze the patterns of the service times in all the venues and state whether these seem reasonable or whether they might reveal possible problems giving rise to customer complaints. It will be critical to this ongoing study that you first identify the venue or venues that may require more investigation. Once you have identified these venues you need to propose possible reasons for the problems that will lead us to further data collection. What additional data do we need in order to get at the underlying problems with customer service?
