Design and development methods do not meet designers' and developers' needs. They are difficult to learn and to use; they are complex, sequential and rigid and thus far from being adapted, reliable and efficient. This paper presents M2Flex, a process metamodel for highly supporting flexibility. M2Flex is based on a recent definition of flexibility along four dimensions: (1) variability, the existence of equivalent choices, (2) granularability, the existence of different levels of details, (3) completeness, the possibility of defining optional components and pre-defined reusable results, and (4) distensibility, the capacity of the resulting process model to be extended or reduced at runtime. This paper shows how M2Flex is original by the flexibility it offers to designers and developers at runtime.
