either simplify or expand ideas
Fishbone - Who Should Create It?Fishbone - Who Should Create It?
s Any team member should know how to create a Fishbone
s All people who are affected by the process should be involved (even if you have to conduct two sessions and combine results)
s Needs to be kept simple

Now create a Fishbone in your groups on a Flip chart to show what areas of projects in your experience have failed. i.e. problem statement = ‘Project failure’
Solution Effect - Where Does It Fit?Solution Effect - Where Does It Fit?s Often people have a choice of potential solutions.

Solution & Effect - Why Do We Need It?Solution & Effect - Why Do We Need It?s Identifies weaknesses and side effects of
proposed solutions Involves team s Highlights where additional refinement of
Control plan / management of buy in needs to occur
s Again helps scope a project’s implementation

s Each branch and sub branch of a Fishbone can be examined to isolate the desired and undesired effects of enabling team to develop a detailed understanding of the influences on project success

s If you have data e.g. number of failures, cost of failures you can add these to the branches to weight them
s If you want to decide where to start the team’s analysis consider n/3 voting to identify areas of most interest
Procedure for FishboneProcedure for Fishbone1. Agree on problem 2. Draw horizontal line in center of page3. Write problem at fish head4. Draw bones - you may use titles: Manpower,
Machine, Method, Measurement, Management, Mother Nature (Environment) - or choose your own as appropriate
5. Brainstorm/copy ideas onto fishbone6. Create sub branches as appropriate7. Zoom in/ Zoom out as appropriate8. Score / Vote as appropriate to prioritize action9. Switch from Cause - Effect to Solution Effect as
appropriate
