  While Enterprise Architecture Modeling (EAM) methodologies become more and
more popular, an EAM methodology tailored to the needs of virtual organizations
(VO) is still to be developed. Among the most popular EAM methodologies, TOGAF
has been chosen as the basis for a new EAM methodology taking into account
characteristics of VOs presented in this paper. In this new methodology,
referred as Virtual Organization Breeding Methodology (VOBM), concepts
developed within the ECOLEAD project, e.g. the concept of Virtual Breeding
Environment (VBE) or the VO creation schema, serve as fundamental elements for
development of VOBM. VOBM is a generic methodology that should be adapted to a
given VBE. VOBM defines the structure of VBE and VO architectures in a
service-oriented environment, as well as an architecture development method for
virtual organizations (ADM4VO). Finally, a preliminary set of tools and methods
for VOBM is given in this paper.
