Steinitz's six questions relate to methods for defining the nature of a design issue and formulating solutions. The questions are based on a six-level process. Assess a study area through description; process or how the landscape works; evaluation or whether it works well; proposed change; impact of change; and decision -- whether it should be changed. Each step is put forward in the form of a question.
The Steinitz landscape planning method the reverses the order, starting with decision, and ending with description, or representation. The framework is passed through at least three times during a project to reach the conclusion. For complex projects, changes in time and scale are added for evaluation, and each proposed change goes through the framework.
In practice, the framework may not be as orderly as the sequence outline suggests, but a design project will pass through each level of the project before the positive "yes" decision is reached. Steinitz includes "do not build" to be a positive "yes" decision. A design problem can be considered at different scales, for example, designing a community, street and house.
