The first step is to do a full analysis of the proposed policy or intervention to understand what the intervention exactly will encompass and aims to achieve, and how elements of the action may influence health and health inequalities. Elements that are important to identify include the strategies used, the populations potentially affected, the key stakeholders involved, the relationship of the policy or intervention to other policies and interventions, and the results from evaluations of other similar policies or interventions. It could be useful to formulate a logic model or programme matrix. A logic model is “a systematic and visual way to present and share your understanding of the relationships among the resources you have to operate your programme, the activities you plan, and the changes or results you hope to achieve.” (W.K. Kellogg Foundation Logic Model Development Guide, 2004). It visualizes how programme inputs and activities will accomplish programme outputs, programme outcomes and eventually programme impacts.
