According to CHAOS Summary 2009 report published by The Standish Group success rates in projects show a serious amount of decrease in 2009. %32 of projects were delivered on time, on budget with all the requirements matched.
%44 of them were delivered but not on time or over budget or with lack of needed functionalities. Personally , in case of software projects, i don’t think a project should be supposed as failed if it was delivered eventually :)Another statistic state that in 2009, %24 of the projects failed completeley,meaning never delivered or never used.
This is what i call failed!
