People, Process, And Predicting Project Success
Source: Project Smart
Great people, people with sufficient functional skills and domain expertise can trump process, good or bad. Good process, process appropriate for the context, will help those people. But great people can overcome bad process to deliver a good product. Bad management, management incapable of understanding how to remove obstacles or how to see the project state, can trump good people and good process. Management that doesn't help is better than management that actually hurts a project.
