There are many styles of Project Management, and many Project Management philosophies to choose from. Some emphasise a plan-based approach, some try to tackle emerging objectives in a dynamic or adaptive way, some emphasise structure and documentation, and others emphasise people. There is Lean management, PMBOK, critical path, the process approach, and so on – but where did the different styles and directions of Project Management originate and how has the discipline evolved until today?
- summarise the historical origins of Project Management,
- provide references and links for further information,
- highlight the most important characteristics of each approach to Project Management,
- show who, where and in what context the approach was created (explain how people came to that approach and what problems they were trying to solve with it), and
- give some indication of the role of each approach in today's Project Management activities.
Since multiple historical lines of development exist, a valuable answer should give some categorisation that allows comparison of differences and similarities in different Project Management approaches.
