Zoning for diversity As production becomes increasingly clean and knowledge-based, as our urban economies tip dramatically to service industries, as racism and ethnic animosities ebb, and as the model of mixed use becomes more and more persuasive and visible, cities are in a position to dramatically rethink zoning as a medium for leveraging and usefully complicating difference, rather than simply isolating it.

The greatest flaw in city zoning Raskin, in his essay on variety, suggested that the greatest flaw in city zoning is that it permits monotony. I think this is correct. Perhaps the next greatest flaw is that it ignores scale of use, where this is an important consideration, or confuses it with kind of use.

The air doesn't know about zoning boundaries Work uses suggest another bugaboo: reeking smokestacks and flying ash. Of course reeking smokestacks and flying ash are harmful, but it does not follow that intensive city manufacturing (most of which produces no such nasty by-products) or other work uses must be segregated from dwellings. Indeed, the notion that reek or fumes are to be combated by zoning and land-sorting classifications at all is ridiculous. The air doesn’t know about zoning boundaries. Regulations specifically aimed at the smoke or the reek itself are to the point. Jane Jacobs, The Death and Life of Great American Cities zoningregulationsseparation
What went wrong? If something ships from one of the companies I advise, and it is virtually unusable because of poor design (which as we all know occasionally does happen), you can bet I go directly to the designer and ask how this happened? It is absolutely on the designer to ensure this does not happen, so something went wrong. Similarly, if the product ships and performance is terrible you can bet I go directly to the tech lead with the same question. And most frequently of all, if something ships and the analytics show that it’s either not being bought or not being used, or it turns out that it violates some business constraint like compliance or privacy, you can bet I go right to the product manager with that question.
