A pilot program is a small-scale, initial implementation of a new project, policy, or intervention to test its feasibility, effectiveness, and potential impact before full-scale implementation. Pilot programs are often conducted in a controlled environment to gather data and insights that can inform decision-making for future expansion or refinement of the program. They are commonly used in various fields such as healthcare, education, social services, and technology to assess the viability and success of an initiative before investing more resources.
