Using Statistical Process Control to Improve Air Traffic Processes

1. Choose two cities of interest and research/report actual flight times over a particular weekend, Friday through Sunday. Data sets should include at least ten observations and should be organized in a table for later use.

2. Create a Pareto chart for your flight times.

3. Identify the Upper and Lower Control Limits for any of the three days and draw a graph to represent findings.

4. Calculate the mean and standard deviation of flight times for each day and draw an $\stackrel{\_}{x}$ chart.

5. Create a quality control workflow chart to present to air traffic clients on ways to improve tracking data. Ideas can include measurement improvements.

6. Think about Deming's points 7-9. How can you, as a leader, use statistical processes to improve the effectiveness of flight times?

7. Creatively organize all results and write a summary of your findings to be presented to a board for statistical improvement of air traffic processes.

   1. Include charts and label properly.

   2. Interpret your results from parts 1-4.

   3. Use parts 5-6 to write the narrative of your presentation.

   4. Identify different types of variation and reasons for such data points.
