Software development methodologies may be described in the context of an underpinning metamodel, but the precise mechanisms that permit them to be defined in terms of their metamodels are usually difficult to explain and do not cover all needs. For example, it is difficult to devise a way that allows the definition of properties of the elements that compose the methodology and, at the same time, of the entities (such as work products) created when the methodology is applied. This article introduces a new approach to constructing metamodels and deriving methodologies from them based on the concept of powertype. It combines key advantages of other metamodelling approaches and allows the seamless integration of process, modelling and documentational aspects of methodologies. With this approach, both methodology components and project entities can be described directly by the same metamodel. © Springer-Verlag 2005.
