stepwise refinement ⇝

top-down design

<programming>

(Or "stepwise refinement"). The software design technique which aims to describe functionality at a very high level, then partition it repeatedly into more detailed levels one level at a time until the detail is sufficient to allow coding. This approach to software design probably originated at IBM, and grew out of structured programming practices.
