top-down design

top-down design

[′täp ¦dau̇n di′zīn]
(industrial engineering)
A design methodology that proceeds from the highest level to the lowest and from the general to the particular, and that provides a formal mechanism for breaking complex process designs into functional descriptions, reviewing progress, and allowing modifications.

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.

top-down design

A design technique that starts with the highest level of an idea and works its way down to the lowest level of detail. See top-down programming.
