Why big IT projects always go wrong

Direct link to the research mentioned in the article: <a href="http://arxiv.org/pdf/1304.0265v1.pdf" rel="nofollow">http://arxiv.org/pdf/1304.0265v1.pdf</a><p>It concludes that Big Bang risky projects should be avoided and smaller projects with comprehensive contingency plans should be preferred instead.

In my opinion the problem lies in planning. The bigger the project the more the entropy can start to have fun with it :)
