First Printing and Copy Center has 4 jobs to be scheduled. Production scheduling personnel are reviewing the Gantt chart at the end of day 4. Job D was scheduled to begin early on day 2 and take 6.5 days. As of now (the review point after day 4), it is 2 days ahead of schedule. Job E should begin on day 1 and take 5 days. It was on time. Day Job 123456789 10 11 Job F was to begin on day 3, but maintenance forced a delay of 1.0 day. The job should now take 5 full days. It is now on schedule. D Job G is a day behind schedule. It started at the beginning of day 2 and should require 6 days to complete. E Add the actual progress to the Gantt schedule shown on the right (on which the planned timings have been already plotted as blue lines). Using the line drawing tool, plot the actual progress showing the actual start and the expected finish on top of (overlapping) the maroon dashed line provided just above the job number for each of the tasks.

Now monitor the process. An additional ten days of data have been collected, see table labeled “1st 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 1st 10 days of monitoring. Plot the data for the 1st 10 days on the Xbar and R charts. Is the process in control? If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart.   Based on the X-bar and R Charts that you developed for the 1st 10 days of data, is the process in control?   Group of answer choices No. The X-bar and R Charts are both out of control. No. The X-bar Chart is in control, but the R Chart is out of control. No. The R Chart is in control, but the X-bar Chart is out of control. Yes. The X-bar and R Charts are both in control.
