A key hospital outcome measure of clinical performance is length of stay $($LOS$)$that is$,$ the number of days a patient is hospitalized. For patients at one hospital with acute myocardial infarction $($heart attack$),$ the length of stay over the past four years has consistently decreased. The hospital also has data for various treatment options, such as the percentage of patients who received aspirin upon arrival and cardiac medication for left ventricular systolic dysfunction $($LVSD$).$ The data are as follows:$$Month prior to schedule change$$Month after schedule change$95\%89\%98\%93\%99\%96\%100\%98\%$Number of Flights$1627$Number of Passengers$8,79515,653$Year$2007200820092010$Average LOS$4\mathrm{.}35$ days $4\mathrm{.}33$ days $4\mathrm{.}12$ days $4\mathrm{.}15$ days$$Aspirin on Arrival$$LVSD Medication$$Using passengers per flight as a productivity indicator, comment on the apparent effect of the schedule change.$$PART ONE: Basic Concepts of OM and Value Chains$$Illustrate the interlinking relationships by construct$-$ ing scatter charts, using Excel, showing the LOS as a
