Preparing the Fishbone Chart
Purpose:
The fishbone chart is an excellent proce-
dure for identifying possible causes of a problem. It
provides you with knowledge that you can use to
improve the operations of any organization. This skill
exercise focuses on the
administrative management
model
. It helps you develop the
monitor role
of the
administrative management model. One of the skills
of the monitor is the ability to analyze problems.
Introduction:
Kaoru Ishikawa developed this tech-
nique in the 1960s, and it is now considered to be
one of the fundamental tools of quality management.

Quality circles often use the fishbone “cause-
and-effect” graphical technique to initiate the reso-
lution of a group work problem. Quite often the
causes are clustered in categories such as materials,
methods, people, and machines. The fishbone tech-
nique is usually accomplished in the following six
steps:
1.
Write the problem in the “head” of the fish (the
large block).
2.
Brainstorm the major causes of the problem, and
list them on the fish “bones.”
3.
Analyze each main cause and write in minor
subcauses on bone subbranches.
