The main elements of enterprise architecture and their
relationships are shown in Fig. 3. Three basic elements
have been identified (highlighted in orange colour): methodology,
framework and modelling language (Vargas 2011).
These elements must be provided by enterprise architectures
for successful implementation within the enterprise.
The methodology defines how the EA will be implemented
and how it will develop, use and archive the documentation.
The framework allows for structuring of the elements of the
enterprise architecture and their relationships in a graphical
and simple way, taking into account different views or perspectives
and the life cycle phases. Finally, the identification
of a modelling language allows modelling and understanding
the relationship between the views that make the company,
in a structured way
