Success Is in the Eye of the Beholder
I believe that there are several important lessons to be taken away from this survey. First and foremost, IT project teams enjoy a higher success rate than what we're commonly told. Second, it appears that organizations have their own definition of success, and perhaps even different definitions for different types of projects. Third, Agile software development techniques appear to enjoy a measurably greater success rate than traditional or offshoring projects. Fourth, because we're nowhere near a 100-percent success rate there is still room for improvement. The implication is that software process improvement (SPI) efforts are something that we need to invest in.
