As decisions are made, either in singles, in clusters, or in order to serve an operational principle, each new decision imposes new constraints on future decisions, redefining again the options left in the problem solving space, making certain future decisions imperative, and shifting priorities for the next decision. This cycle of progressive placement of constraints continues until the minutest decision has been made firm. Functional design is a natural companion of design layer theory. Initial constraints on a design problem affect different layers. One project may require a particular medium to be used; another may require a particular social setting. Constraints influence the options available within different layers of the design. Moreover, constraints on one layer ripple effects to other layers, constraining decisions within them.
