If this was the result of the 2008 survey, there's little hope for this round. You have to wonder how the survey designers and participants defined the 'success' that the 'mistakes' screwed up. A fun place to work perhaps? How this relates to the objectives of good software development - satisfied clients and users, good profits, more contracts - is anyone's guess.

Reminds me rather of a survey of school kids about their teachers. Results may be interesting but don't tell you much about how good the school is. (Hmm, the transactional analysts would enjoy this...)
