One flaw with the survey... (Score 1)

...is the fact that it is a survey. I think that this type of analysis would have shed more accurate insight if outside 3rd parties had analyzed the development projects rather than having people involved with the project(with their own biases, attachments, perspectives etc...) complete a questionnaire. 1) Outside parties would have fewer biases about why a project fails. 2) The usability adage "trust what people do, rather than what they say they do" applies here. 3) There is a possibility that the people that were surveyed were major contributors to the failure, and hence should we trust their judgment?
