Logic Model

The logic model* brings together all of the components of a programme and places them into an appropriate sequence similar to the log frame, which contains similar components, means of verification for activities, and outputs* that you can easily convert into a logic model (Figure 7).

A good logic model allows you to:

• Structure the way to look at the activities you plan to measure as indicators of the intervention’s success.
• Map which intervention components facilitated specific changes and outcomes*.
• Clarify the scope of your project and its activities, by referring to activities and components and their related outcomes among project participants.
• Clarify and finalize vague or ambiguous ideas about intervention or evaluation activities so that you have no major intervention or measurement surprises as the project is rolled out.
• Better support both project implementation and evaluation staff.

We recommend starting your logic model with a statement of the problem, which is extremely helpful in explicitly stating the need to understand the issues underlying the problem that your project intends to address.

With respect to the issues and question(s) you plan to address, you should already know the current state of the field and the findings to date before embarking on a project and using resources to measure its impact.
