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 of, separation and/or concerns:
“... the separation of church and state means separation—absolute and eternal—or it means nothing.”
—Agnes E. Meyer (1887–1970)
“Like sleep disturbances, some worries at separation can be expected in the second year. If you accept this, then you will avoid reacting to this anxiety as if it’s your fault. A mother who feels guilty will appear anxious to the child, as if to affirm the child’s anxiety. By contrast, a parent who understands that separation anxiety is normal is more likely to react in a way that soothes and reassures the child.”
—Cathy Rindner Tempelsman (20th century)
“New inventions can and will be made; however, nothing new can be thought of that concerns moral man. Everything has already been thought and said which at best we can express in different forms and give new expressions to.”
—Johann Wolfgang Von Goethe (1749–1832)
