The other aspect is the process of making decisions which do not immediately bear upon the physical forms of the built environment but nevertheless affect it very significantly. This part of the process is the making of laws, regulation and plans usually by non-designers. It also includes how the community is involved in urban decision making.
An example is the regulations affecting the formal consumption of food and drink out on the footpath. If a bicycle is defined as a vehicle then it will not be allowed in places intended only for pedestrians. How those regulations work will have a major impact on the urban design quality of a place. How decisions are arrived at will bear upon their end outcome and effectiveness. This part of the process also includes politics.
The outcome (the product)
The other part of urban design is the end result. This is usually seen as the physical arrangement of a city or town (the product). However, it would be more desirable to think in terms of outcomes rather than products. The outcomes may be buildings which enclose
