Investment Plans included objectives such as public transport efficiency, or promotion of "integrated development" of both housing and residential infrastructure, along with so-called productive investments such as industrial parks or factories. Strategic investment plans acknowledged that the urban area was larger than a project area, that some spaces deserved higher priority than others, and that "strategy" meant making choices in a spatial context. The challenge, therefore, was to determine which rules might encourage behaviour in specific directions and what were the so-called "enabling conditions" required for desired outcomes to be achieved. The difference lay in the assertion that market-oriented policies were intended to affect not only individual entities, both corporate and otherwise, but the whole pattern of behaviour of all entities, both individually and collectively.
