The document discusses evidence-based design for interior designers. It outlines the design process as having systematic and logical problem solving methods including defining problems, research, generating alternatives, and implementing solutions. Research must be relevant to specific projects and is vital for effective design solutions. The programming process is described as the most important step, involving problem seeking and analysis to establish goals, gather facts, specify needs, and make decisions. Observation methods like unstructured observations and structured behavior mapping are also discussed.
