Project management requires the combination of technical skills, people skills and industry-specific knowledge. It is a true hybrid environment. This knowledge and its application also forms a beautiful paradox. Our quest to gain skills is never complete and always expanding, but the most effective tools are usually the simplest. Smart people do very simple things to achieve desired outcomes. Yet, they probably considered fifty alternatives before choosing the most effective, simple approach. You must know a lot to be confident your choice is apt.
Knowledge and experience in project management follows the same pattern. Learning about project management, how to work effectively with people, and our industry domain is never complete. We then use this knowledge to choose the best action, which for ease of understanding and implementation, is usually a simple course of action. I call it Expansion and Contraction, but there is probably a simpler name I will learn about one day.
