Funny, reminds me of two projects I had at the same time - internal: we now follow IEEE except the first and last book (of 6) because the management doesn't have time for that crap. External: by the way, the (big!) customer you are consulting have gone to Six Sigma, remember to ask the developers but not the management or sales, they are not include because they don't have time for that! There is nothing like IT - or is there?
