As chief operating officer of a local community hospital, you have just returned from a three-day seminar on quality and productivity. It is your intention to implement many of the ideas that you learned at the seminar. You have decided to construct control charts for the upcoming month for the proportion of rework in the laboratory (based on 1,000 daily samples), the number of daily admissions, and time (in hours) between receipt of a specimen at the laboratory and completion of the work (based on a subgroup of 10 specimens per day). The data collected are summarized and stored in HospAdm. You are to make a presentation to the chief executive officer of the hospital and the board of directors. Prepare a report that summarizes the conclusions drawn from analyzing control charts for these variables. In addition, recommend additional variables to measure and monitor by using control charts.
