In Project Management currently about 10 different methods are bing used. When we restrict ourselves to the Information and Communication Technology and to generally applicable methods within this framework, we can distinguish the following Project Management methods:
- PMBoK (Project Management Book of Knowledge). This method is developed by the Project Management Institute (PMI) from the USA and is based on ' best practices ' (www.pmi.org). In fact, this methodology can be used in multiple areas such as construction.
- PRINCE2 (Projects in a Controlled Environment). This method covers the management, control and organisation of a project. PRINCE2 is developed and maintained by the British semi-government organization Office of Government Commerce (OGC, http://www.prince-officialsite.com/).

- Agile/Scrum. The term ' scrum ' comes from the rugby world and is in fact the struggle to hit the ball. The Agile method has different other methods which Scrum is used the most. This is still a relatively new method developed by Ken Schwaber and Jeff Sutherland. On various websites and ' blogs ' are heated discussions about the 'right' description etc. (http://bit.ly/1ixDnJK).
Scrum consists of a framework of roles and rules and is not associated with a specific technology domain. An important feature of Agile is that the people from the 'business' are actively involved in the development. The development process is iterative and incremental. System parts are through share deliverables expanded and improved. In this context, it is crucial to keep an eye on the total system so that at the end of the overall project is delivered what was agreed upon.
In the past, and maybe still here and there, use was made of the 'waterfall' model for the implementation of mainly software development projects. During the course of the years, various new waterfall models have been developed such as the model of Royce, "sashimi" model, aortic lifecycle model and the V-model. The principle of the waterfall model is that is worked in several phases. Each phase has its own level and determines the order. Next phase for phase is carried out sequentially.
A major disadvantage of this model is that changes and results ('deliverables') are not simple and that it can take a long time before something is delivered. In our present society this approach is no longer feasible mainly because of the very 'fast time to market which in practically all companies should be short. As a company you need to be able to respond to changes quickly. All this has led to the Agile method in which in relatively short periods (between plm. 1 and 4 weeks) something is delivered. Because of this changes are relatively easy to implement.
