Discipline in project management: Why is it hard to find and what is its most challenging obstacle?

Project Management is not new to industry, R&D or even technology management. The facts about its success in application are well documented and demonstrated. It does deliver, it is known to be the best approach, it´s efficient and business knows it. So why, given these known conditions and facts that we as individual project managers find it so difficult to apply the practice on a consistent basis? What holds us back, what obstructs us from applying it entirely and what and who should we say is the most challenging obstacle? This application paper will describe through various citing´s, interviews and publication reviews, some of the barriers and obstacles of discipline in a profession that is securely founded in discipline. It is anticipated to provide practicing Project Managers a little more motivation or courage to add a practice of personal discipline to their project management practices. This is the initial groundwork for an industry wide research survey on the challenges and costs associated with project management discipline.
