The connection between logic models and systems thinking concepts

This article examines the relationship between systems thinking concepts and the logic model. Two notable shortcomings of the logic model are illustrated: depicting the program theory linearly and failing to place the program in context. Both issues lead to an artificial depiction of reality making evaluation findings difficult to interpret. Systems thinking concepts are defined and how they address these shortcomings is discussed. This article then demonstrates how many systems thinking concepts are evident in the logic model; although in a limited way. This article concludes by noting the importance of using system concepts when answering evaluation questions related to system dynamics and interrelationships
