Hi, I need help with my systems operations management case assignment that is due March 15 at 4:15pm or also known as 16:15 in military time. (UTC-08:00) Pacific Time (US & Canada) I have an attachment with the case and the directions. 

Requirements:

• Use Excel to construct an x – chart and an R – chart for this data.

• What conclusions can you draw from the control charts regarding the results of the quality improvement efforts? Have the goals concerning service times been reached? Is the process in control?

• What would your recommendations be with respect to continuing the quality improvement program? What other statistical tools might Dave’s Burgers use in its quality management program?

Written in memo form and should not be more than 3 pages including any displays (graphs, tables, etc.).
