Assume you have been asked to help analyze the data and to make recommendations for improvement. Analyze the data using a check sheet, a Pareto diagram, and run charts. Then construct a cause and effect diagram for the leading category on your Pareto diagram.

Do the results of the last two weeks reflect improvement? Based on your analysis, prepare a list of recommendations that will address customer complaints.
