Program Theory is a framework used to understand how a program is intended to work. It outlines the relationships between the program's activities, the resources used, and the expected outcomes. By clarifying these connections, stakeholders can better assess whether the program is likely to achieve its goals. This theory often includes components like inputs, outputs, and outcomes. Inputs refer to the resources needed, outputs are the direct products of the program's activities, and outcomes are the longer-term effects. By analyzing these elements, evaluators can identify strengths and weaknesses in program design and implementation.
