Because most IT projects are not really pure play IT projects? If we do a comparison with construction, once requirements are done, design is completed, it is civil engineers all the way through. But in IT it requires input from non-IT folks and the amount of disconnect is mind boggling. So say creating a product for a construction company, which can predict the stress on a building. It requires coders who have no formal education on this aspect to work with civil engineers who have no formal education on how software works. So both way communication tends to be terrible. Then the questions are what exactly constitutes a project and what are failures? Taking the example of the quoted A380 example.
