A Fishbone Diagram is called the Ishikawa Diagram or Cause and Effect Diagram. The reason it is called A Fishbone Diagram is because it looks like the shape of a fish skeleton. The Fishbone Diagram is a tool use in continuous quality improvement to find possible causes for a problem or event.
Case Title or Subject
Completing the fishbone diagram doesn't take long. The team or individual needs to ask the question Why 5 times in the process.
Try this example:
Problem: Patient not taken back to their room after radiology procedure in a timely manner. The average wait time is 20 minutes.
Fill in each section of the diagram
Effect: Patient wait after radiology test is 20 minutes. Desirable wait time: less than 5
Machinery: No wheelchairs available, Longer time to take images than expected
Methods: Using patient elevator only, imaging mostly performed at night
Materials: Notification of patient needing transportation via phone in office, not but imaging room
Manpower: Night shift has lower staffing needs so imaging staff must transport their own patients
Management: From using the Fishbone Diagram, one can find out the causes and work to change processes in order to have the desirable outcome.
