Programmatic concepts
Programmatic concepts are abstract approaches the designer can use to solve the client's goals and needs. This differs from the design conce pt , which represents the physical solution. Twenty-four programmatic concepts are cited in the Interior Design Reference Manual, but here are a few: EXPANDABILITY; HIERARCHY; DENSITY; GROUPING; FLOW; PHASING
