Program logic is a systematic approach used to outline the steps and processes involved in a program or project. It helps clarify how specific activities lead to desired outcomes by mapping out the relationships between inputs, outputs, and goals. This framework is often visualized through flowcharts or logic models, making it easier to understand the program's structure and purpose. In the context of evaluation and project management, program logic serves as a foundation for assessing effectiveness and efficiency. By clearly defining objectives and expected results, stakeholders can better track progress and make informed decisions about resource allocation and program improvements.
