top-down design

a deductive approach in which the design of a system or product is driven by conceptual guidelines rather than by empirical data (e.g., test results or user feedback). For example, menus or other displays of functions on a computer interface generally follow a hierarchical structure from basic function categories to groupings or specific tasks via a series of submenus. Compare bottom-up design.
