I need resources/techniques for applying Lean Six Sigma to
Sarbanes-Oxley compliance. Very detailed/technical.

The right answer to this question will be research resources (pdfs,
IEEE articles, business articles, academic papers) that specify ***in
detail*** how Lean Six Sigma can be directly applied to Sarbanes-Oxley
compliance to increase efficiency, save money, provide assurances,
decrease time, and/or increase accuracy and reliability.

I want to see as many actual techniques and calculations as possible
for achieving this. The more in-depth and detailed the better.
Innovative solutions welcomed.

Thank you very much for your help.
