Exploratory research is initial research conducted to clarify and define the nature of a problem. It does not provide conclusive evidence but aims to discover new ideas and screen alternatives to inform subsequent research. Common methods of exploratory research include secondary data analysis, experience surveys, case studies, and pilot studies which employ techniques like focus groups, projective techniques, and in-depth interviews. The goal is to diagnose situations and concept test ideas in a qualitative way before definitive research is conducted.
