I confess that I do not know where to draw the line between
Requirements, System Analysis, System Architecture, Software Engineering,
Development, and Quality Assurance. I have interests in each and I
call myself a system architect. For now, I see System Architecture as
including concerns for requirements identification and system formulation
through verification of requirements satisfaction. System architecture
includes architecture of system delivery as well as architecture of
sustaining operation. This is a broad view, and essential to
achievement of coherence and conceptual integrity -- system architecture
done on purpose. I will settle for that now, and factor off parts that
seem to be too far below or above the architectural abstraction as it
becomes useful to do so.
I will stop short of internal architecture, the kind
that compartments functions underneath the covers of configurable units.
(It is unclear to me why functions are supposed to live in boxes and I have
little patience for it.)
The ceiling on system architecture is far enough into
the world of users to include the confirmable articulation of those key
values that set the context for the system. Meanwhile, as my associate
Bill Anderson is prone to say, "It is turtles all the way down."
