Pilot experiment
A pilot experiment, pilot study, pilot test or pilot project is a small-scale preliminary study conducted to evaluate
Implementation
Pilot experiments are frequently carried out before large-scale quantitative research, in an attempt to avoid time and money being used on an inadequately designed project. A pilot study is usually carried out on members of the relevant population.[1] A pilot study is used to formulate the design of the full-scale experiment which then can be adjusted.[1][2] The pilot study is potentially a critical insight to clinical trial design, recruitment and
Applications
In sociology, pilot studies can be referred to as small-scale studies that will help identify design issues before the main research is done. Although pilot experiments have a well-established tradition, their usefulness as a strategy for change has been questioned, at least in the domain of environmental management.[3] Extrapolation from a pilot study to large scale strategy may not be assumed as possible, partly due to the exceptional resources and favorable conditions that accompany a pilot study.[1]
In clinical research, studies conducted in preparation for a future randomized controlled trial are known as "pilot" and "feasibility" studies, where pilot studies are a subset of feasibility studies.[1][4] A feasibility study asks whether the study should proceed, and if so, how. A pilot study asks the same questions, but also has a specific design feature: in a pilot study, a future study is conducted on a smaller scale,[1][5] which, if having produced positive results, may lead to a Phase I clinical trial.[6] The use of pilot and feasibility studies to estimate treatment effect is controversial, with ongoing methodologic discussion about appropriateness.[7]
A checklist was published in 2016 to provide guidance on how to report pilot trials.[8]
