41. Prepare a memo from the City Manager to the City Council on the following:
A citizen has come to your city council meeting complaining about the lack of inspections with rental property. Her observation is that the city is not keeping up with inspections and enforcement and wants to know what is going on. As city manager, you have directed your staff to prepare a report on the rental inspection program. At this point, you are primarily concerned with workload. You have two benchmarks: in the community adjacent to you (which is similar in population and housing conditions), they report that their inspectors conduct 47.5 inspections per week per inspector; that national average reported by the International City County Management Association is 45.5 inspections. On the attached spreadsheet is the housing inspection data for the past year. You have two inspectors assigned full-time to inspect these rental properties. How do your inspectors compare with the benchmarks? Write a two-page memo explaining your findings and present graphically the information that you believe to be pertinent to the city council and the citizen. You will note that several weeks have “outliers” in that the inspection production is far below what you believe to be the average of normal weeks. Explain the outliers (you can make up an answer) and determine whether you should include them in the overall data. Justify your reasoning in the report as well.
