In this activity, you will apply some of the Quality Tools Management (QTM) to examine errors
during the turnaround of aircraft for a large, fictional airline.
This chart provides the number of errors reported for a seven day period for the events completed
during the turnaround process.

Complete the steps in each section and then submit your assignment for grading. Submit one
spreadsheet containing a tab for each TQM tool used. Include all recommendations,
interpretations, and suggested actions in the spreadsheet. Current APA formatting and references
are not needed for this activity.
Step 1: Develop a Histogram and Pareto Chart
Use Excel and the error data to develop a histogram and pareto chart. Review the charts and
draw conclusions from the data. What actions would you suggest to reduce the number of errors?
A histogram shows the frequency of occurrences of a variable. For this exercise, we want to look
at the total errors by day so your Histogram should have 7 bars, one for each day of the week.
For the Pareto chart you should also have seven bars, one for each of the events.
Step 2: Build a Cause-and-Effect Diagram
Pick one of the seven events in the Errors Reported in a Seven Day Period chart and build a fishbone cause-and-effect diagram.
Hint: check out this video for some more information on how to create a cause-and-effect
diagram: How to create cause-and-effect diagrams (YouTube 3:16). (Links to an external site.)
Step 3: Produce a Scatter Diagram
Continue with your examination of ways to reduce the error rate. Use the Servicing Delay vs.
Support Staff data to produce a scatter diagram comparing the galley servicing delay versus the
number of staff you are short of on each respective day.

Can you draw any conclusions based on the chart? Based on this data, what actions would you
recommend to reduce the galley servicing delay errors?
Hint: you should end up with a linear regression type line. Check out this video for some more
information on building a scatter diagram: Excel 2016: Creating a Scatter (XY) Chart (YouTube
4:34). (Links to an external site.)
Step 4: Create a Statistical Process Control Chart
Use the Servicing Delay vs. Support Staff data from Step 3 and the Excel OM plugin to create a
statistical process control chart (SPC) (using the c Chart and make sure to click on the graph
box). While this method is best used in manufacturing, you can apply the principles to our
problem.
Explain the chart and indicate whether it provided you with any additional information on ways
to reduce errors and improve quality.
Hint: using Gallery Service delay data only, from step 3.
Step 5: Submit the Assignment
Submit one spreadsheet containing a tab for each TQM tool used. Include all recommendations,
interpretations, and suggested actions in the spreadsheet. Current APA formatting and references
are not needed for this activity.
