What are Standardization
Areas and Domains?
Standardization Area:
A complete project to be standardized through the
standardization of every aspect required for the
completion of the standardization activities
required. This could be associated to the vertical
standardization concept.
Standardization Domain:
The aspect or one of the aspects for which
standardization activities are required for the
completion of the standardization activities required
by an Standardization area. This could be
associated to the horizontal standardization
2
concept.
