7. Tips to Create Fishbone Diagram
Organize a team to carry
out the undertaking rather
than rely on your own.
Be clear about the major
categories of causes of the
problem (written as
branches from the main
arrow).
Brainstorm all the possible
causes of the problem.
Make full use of the
fishbone diagram tool to
help the team focused on
the causes of the problem,
rather than the symptoms.
Same causes can be
written in several places if
they relate to several
categories.
If you choose to draw on
hand, consider drawing your
fishbone diagram on a flip
chart or large dry erase
board.

9. What What should be improved? What is the purpose of improvement.
Is there anything else to do? What should be
done?
Where
Is the worker’s orientation or method correct when changing the
workplace?
Why operate in that location? Which is the best
location to achieve highest efficiency?
When Change the time, period or sequence of the operation.
Why perform at that time? Will it be better to
execute at other time?
Who
Manpower, collaboration or task assignment. Check and discuss this
issue again.
Why designate someone as the person in
charge? Is there a better candidate?
How
Change the method or procedure so that less manpower is needed.
Apply the method that requires less degree of proficiency and
expense.
Why to do it? Is there better method to replace
the current one?
Why
Doubt everything again. Think over and discuss the above 5
questions by asking more why and then find out the best solution for
improvement.
