1. (3.63) One of the major measures of the quality of service provided by an organization is the speed with which it responds to customer complaints. A large family-held department store selling furniture and flooring, including carpet, had undergone a major expansion in the past several years. In particular, the flooring department had expanded from 2 installation crews to an installation supervisor, a measurer, and 15 installation crews. The business objective of the company was to reduce the time between when the complaint is received and when it is resolved. During a recent year, the company got 50 complaints concerning carpet installation. The data from the 50 complaints, organized in Furniture represent the number of days, between the receipt of a complaint and the resolution of the complaint.
