Bulldog Consulting had several ideas of ways to improve the process, but a barrier gate that would only allow one car to enter/exit at a time was perceived as the best alternative.
|
- As the plans for improvement were suggested to management, we began to collect pre-data from the complexs security cameras.
|
- From the videotapes, Bulldog Consulting was able to measure during peak hours the number of cars that entered through the exit, number of times the gate was hit, and the number of times the gate broke.

| Pre-Data |
| Day | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| # of Enters Through Exit | 10 | 6 | 8 | 11 | 16 | 19 | 9 |
| # of Times Gate Hit | 0 | 0 | 0 | 0 | 0 | 1 | 1 |
| # of Times Gate Broken | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
|
- From the pre-data, a control chart was devised to give the 95% confidence interval for the enters through the exit gate.
