How-to
Gather the project team and
appropriate stakeholders for a brainstorming session.
For each category, list all
possible causes or process inputs. You can create secondary categories for the
primary categories, then list the causes or process inputs under the secondary
categories. If the standard categories of the causes are not appropriate for
the problem, create new ones. Fishbone diagrams can include any type of cause
that you want to investigate.
Identify the most important
causes.
Note
You can quickly brainstorm ideas in the brainstorming list, then drag
them to the diagram to create associations between related ideas. For more
