What is a key characteristic of prescriptive theory?

A key characteristic of prescriptive theory is that it provides detailed instructions for creation and management. This type of theory goes beyond merely describing phenomena; it actively guides practitioners on how to design, implement, and manage architecture and planning practices. This guidance can include specific techniques, methodologies, or strategies that professionals can use to achieve desired outcomes in their projects.

In contrast, other options highlight different aspects. For instance, the description of merely describing phenomena without guiding actions pertains more to descriptive theories, which focus on observation rather than prescription. The mention of subjective observations aligns with interpretive or qualitative theories, which prioritize personal insights over systematic guidelines. Lastly, theories aiming to understand social structures would typically fall under sociological or critical theories, rather than prescriptive ones that emphasize actionable frameworks. Thus, the uniqueness of prescriptive theory lies in its proactive approach to providing frameworks for action in the field of architecture and planning.
