Servicing Delay vs. Support Staff data

Create Cause-and-Effect Diagrams

Event	Sun	Mon	Tues	Wed	Thur	Fri	Sat
Galley servicing delayed	3	6	5	11	5	4	10
Missing galley support staff	2	3	3	7	3	3	7

Determine the possible causes of the problems. Galley servicing delays showed the highest number of problems on our original check sheet, so think about possible issues with galley servicing and produce a cause-and-effect diagram (also known as a fishbone or Ishikawa diagram). Use as least 4 categories and think of several causes for each of the categories.
