DESIGNING A CONTROL CHART EXAMPLE Fujiyama Electronics, Inc. has been having difficulties with circuit boards purchased from an outside supplier. Unacceptable variability occurs between two drilled holes that are supposed to be 5 cm apart on the circuit boards. Thirty samples of 4 boards each were taken from shipments from the supplier as shown in the data listed below. Construct x and R charts for the process using the following data.

In an existing process, we have found that the lower control limit for X-bar chart is 8.08. Whereas, the lower and upper control limits for R-chart are 0 to 2.25 respectively. The following measurements for one sample are taken: 8.5, 8.9, 8.28, and 8.7. Using both the X-bar chart and R- chart for this particular sample, what we can conclude about the overall process a. Insufficient information to conclude b. Process is in-control C. Perfect process d. Process is out-of-control.
