Architecture (EA) data is used for:
gaps and requirements determination,
process technical oversight,
3) an objectively defensible
Program, Planning, and Budgeting process,
capabilities-based portfolio management,
5) doctrine and
standing plans development, and
6) the top-level
of systems engineering.
Because EA addresses all the systems relevant to the enterprise, whether
within or external to an organization, it addresses much of the same data
as System of Systems Engineering (SoSE) and because it starts with mission
capabilities and then derives solutions to meet the mission, it uses much
of the same data as Mission Engineering.
And because the system in Systems Engineering (SE) means the whole
configuration that accomplishes a set of functions, not just the materiel
but also the operators, policies, and environment, much of the same data is
relevant to SE.
