I have published today an excellent article on PM Hut on Project Failure (which seems to be an issue gaining steam across PM Blogs). The article is entitled [url=http://www.pmhut.com/successful-it-project-management-tips-to-avoid-fail... IT Project Management - Tips to Avoid Failure[/url].
What's interesting about this article is that it first defines project failure, lists its most important causes, and finally suggests a solution to each & every one of the previously mentioned causes.
Notice the lack of communication being the first cause of project failure, which is already mentioned in a thread on manager tools [url=http://www.manager-tools.com/forums/viewtopic.php?p=17843]here[/url] (in my opinion, however, the main cause of project failure is highly subjective, some say that it's the lack of executive support).
