The first step in a process evaluation is to develop a logic model. Logic models visually represent the theoretical framework of a program, describing the necessary components of a program, outlining its sequence of activities, and highlighting the relationship between those activities and their desired effects. They are designed to assist program administrators and policymakers in understanding overall objectives and solidifying the key components of a program--necessary resources, associated activities, desired results, and the overall impact. They are used to clarify strategies, identify flaws in a program's theoretical framework, build a shared understanding about how components work together, and establish timelines.

The development of a logic model requires an explicit statement of the initiative's components and goals, from the resources it uses to the ultimate impact it hopes to make. The following chart defines the elements that should be included in a logic model, along with examples based on a workforce initiative.

By articulating the goals and expected outcomes of the re-entry program, logic models assist policymakers, program administrators, and community members in describing, discussing, and improving program planning and implementation. As implementation is underway, logic models clarify the connection between resources, program activities, and desired outcomes; make the need for adjustments readily apparent; and provide an inventory of the necessary components of program operation.
