In many cases, the choice of term is based on local responses to the words theory and logic (each of which can be seen as unpalatable) and on the terms used in the specific texts used by the evaluators.

Like program theory, program logic can be used in two broad ways to guide an evaluation: For summative evaluations, program logic can be designed to test the articulated theory and to build evidence cumulatively to ...
