Fishbone Model
 

Hi,

I want to build an Ishikawa (fishbone, cause-effect) model based on a data
set in an existing spreadsheet.

I am aware that I can purchase plug-in solutions, but none of these permit
the level of comlpexity that I am after.

Is anyone aware of a free tool that produces a fishbone output that I could
modify to meet my own needs?

TIA

Dave
