This leads to the identification of a number of viewpoints in the enterprise, which materialize both
the principal groups of issues that will have to be managed and also the participants concerned. Determining viewpoints provides real structure to the organization and the work to be carried out, by configuring the types of problems to be dealt with and the nature of the people who will be involved. This is why this concept has become increasingly important since the 1990s in modern methodologies, such as RM-ODP (for network architectures), RUP, Zachman (the reference in terms of enterprise architecture), Praxemec (enterprise method), MODAF,d DODAF,e and of course TOGAF. The concepts of
viewpoint and view are standardized in the IEEE 1471-2000 norm.
