Dave’s Burgers is striving to keep up with its competitors in the market. The company constructed drive-through windows at all of its locations in order to increase customer traffic. The company had continuous problems after installing these drive-through windows and actually lost some of its market share to its competitors.

These changes brought significant and immediate improvements in service speed and quality and increased their market share by 5% in the Charlotte restaurant.
The management team wanted to ensure that quality service was being maintained and that service time remained fast. The quality team decided to use a statistical process on a continual basis.

By analyzing the data and the charts constructed it can be determined that the process is out of control and does not currently meet design specifications. This means that the process should be further modified in order to seek improvements in service speed at Dave’s Burgers.
