You could argue, as some of the commenters do, that his isn't workable. Who cares? This is far and away the best demonstration of the proper interaction between designer and client that I've seen. For me, it's more important as an ideal than as a workable plan. Once the ideal is defined, then a workable subset of these rules can be made. When no ideal exists, what do you work towards? The Design Constitution

Great work results from a near obsession with detail and nuance. Done right, a brochure, a web site, a catalog, and so on, is so carefully structured, changing a single significant element can drastically impact the whole. Rather than dictate specific changes to a design--"move this here" or "change the color to,"--let's agree the Client will request a new design or a variation of the original that addresses specific problems.
