What is architecture? It is:
- the art & science of designing and erecting buildings
- A style and method of design and construction
- Orderly arrangement of parts; structure: the architecture of the federal bureaucracy; the architecture of a novel
- Computer Science: The overall design or structure of a computer system, including the hardware and the software required to run it, especially the internal structure of the microprocessor
We follow Govt and industry standards to build detailed, accurate architecture
products that conform to specification while conveying the critical essence of a system. An architecture
is not merely a set of diagrams about a system, but is the distilled key details and perspectives needed
to build and operate the system. Im general, an architecture includes: form; materials; structure;
aesthetics; use patterns; maintenance; construction; safety. An architecture is
“the structure of components, their relationships, and the principles and guidelines governing
their design and evolution over time.” (IEEE Std 610.12) For IT, architecture includes: network diagrams;
software models; communication protocols; hardware connections.
Importantly, an architecture must include the how, who, when, why, where,
what of design, funding, decision-making, development, operation and maintenance. Why must all of
these “soft” issues be included? It has been learned over many years of large scale IT programs that
organizational or technical issues can dominate systems engineering to the exclusion of the other. However,
real success depends on blending people, process, technology ad working with this complete perspective.
There are several standard EA frameworks: Federal Enterprise Architecture
Framework (FEAF); Zachman framework; The Open Group Architecture Framework (TOGAF); Object Management
Group (OMG) Model Driven Architecture (MDA); and, Department of Defense Architecture Framework (DODAF).
TECHi2 has extensive experience with FEAF and DODAF. The pictures below show just a few examples of the
many in-depth coordinated architecture sets we have developed for clients. The figures below are DODAF
OV-1 operational view, OV-5 operational activities (A0 and A1), SV-1 system view, and a
use case for data services.
