Tom Graves writes about whole-of-enterprise architecture, where the enterprise is far greater than any single organisation or even individual markets. Similarly, whole-of-enterprise architecture concerns go far beyond the technology domain.
When working at the scope of individual systems, I have realised that we can benefit from taking a similarly whole perspective: I suggest thinking in terms of whole-of-system architecture can be useful and, in my work, necessary. Software systems certainly play an important role in my work, but people play vastly more important roles. As do relationships between people, groups of people and various forms of organisations. Furthermore, we need to talk about processes and data. The list goes on an on.
Even when thinking only about the technology aspects of such whole-of-system architectures, we usually have to consider runtime (or deployment) architecture concerns, development-time concerns (form, function and structure of code) as well as the tools and processes for helping us to build, deploy and manage the technology components of the system.
Thinking about this further, we might consider a system in this broad sense to be a fractal element of a larger enterprise, and therefore, perhaps, a small enterprise in itself. Consequently, whole-of-enterprise architecture insights may well apply. If so, whole-of-system architecture can then be understood as a specific type of whole-of-enterprise architecture (i.e. one tied to the system scope).
Having gotten the above out of my system, I can now start to sort it out. Would you care to help?
