Separation of Concerns
In more mature engineering disciplines such as mechanical, civil and electrical engineering, the designers are separate from the implementers. That is, the engineers who generate design documents are not the same individuals who actually build things (such as mechanical parts, circuits, or roads, for instance). In software engineering, it is more common to have the architecture, design, implementation, and test functions performed by a single individual. In particular, the design and implementation of source code is commonly integrated.
This resembles the early phases of industrialization in which individuals would both design and build things. More mature organizations have separate test groups, but the architecture, design, implementation, and unit test functions are often performed by the same highly trained individuals.

Famous quotes containing the words separation and/or concerns:
“Just as children, step by step, must separate from their parents, we will have to separate from them. And we will probably suffer...from some degree of separation anxiety: because separation ends sweet symbiosis. Because separation reduces our power and control. Because separation makes us feel less needed, less important. And because separation exposes our children to danger.”
—Judith Viorst (20th century)
“Art and science coincide insofar as both aim to improve the lives of men and women. The latter normally concerns itself with profit, the former with pleasure. In the coming age, art will fashion our entertainment out of new means of productivity in ways that will simultaneously enhance our profit and maximize our pleasure.”
—Bertolt Brecht (1898–1956)
