Carvind,
Not sure what exactly you are looking for. I believe there's nothing wrong with the 'standard'
FMEA format. May be you need some kind of a software (not just a spreadsheet) that provides some powerful analysis facilities?
I would suggest you do a web search for tools such as C&E Metrics or Ishikawa diagram.
www.isixsigma.com is good site for all info related to Six Sigma.
