This describes the concept of a functional-only architectural focus, an extreme example, where architects consider only their functional domain. Here, only half of the system being built is actually being consciously 'designed', the remainder is being evolved by development teams (who may or may not know how to architect large suites . . .

Software architecture is the bridge between mission/business goals and a software-intensive system. Quality attribute requirements drive software architecture design. Choosing and designing an . . .
Software Architecture in Practice
Recap on extrinsic quality factors
Extrinsic quality factors are key concepts for business and architecture stakeholders. [Bass et al, 2013] use quality factors to describe the architectural characteristics of a system -
availability, modifiability, performance, security, testability, and usability
as well as...
qualities, such as . . .
Some tips from Eberhardt Rechtin
On the design of testable systems, Rechtin provides us with several heuristics [Rechtin, 1991] -
To be tested, a system must be designed to be tested
This sounds self-evident, yet, within many architecture silos, a view persists that testability is the concern of development and testing teams. Are they missing something?
The test setup for . . .
