As cited by Gartner, project failure rates are not improving based on a combined set of anecdotal and survey data, it seems that people believe projects are continuing to fall short of their goals:

• 82% of employees within companies with significant organization wide projects under way believe those projects will fail
• 78% believe they are working on a “doomed” project
• 90% knew early on that the project would likely fall short of the objectives
• 81% believe it is impossible to approach the failing project’s key decision-maker 

And they are usually right….
