A pilot study or feasibility study is a small initial study that is conducted to test the practicality and feasibility of a full research project. This study type evaluates if the planned study could be successfully implemented and focusses on aspects such as recruitment, resources and study procedures. A feasibility study will examine the overall possibility of conducting the research, while a pilot study will test the research methods on a small group. Both of these can help identify any potential problems and refine the processes to ensure a main study runs smoothly.
