Measuring Systems-Level Change
Addressing food access at the systems level requires engaging with and targeting more than one of the six sectors of the food system in the U.S.:
- Retail and market
- Waste and recovery
The more sectors of the food system that are included in any initiative or program, the greater the potential for comprehensive, sustainable change. Because of the complexity of the food system, food policy councils or other diverse collaborative workgroups often spearhead and oversee the work.
Evaluation of systems-level work can easily feel daunting, so it may be helpful to consider the food system as a program like any other in need of evaluation. Most programs utilize a variety of traditional evaluation designs that often involve collecting data pre-, post-, and sometimes mid-program to monitor change over time. Please see the Rural Community Health Toolkit for examples of different traditional evaluation designs.
Systems evaluation, on the other hand, is gradual, and change is slower. As a result, tracking of trends will be more robust if data collection occurs multiple times and at regular intervals during the initiative. For this reason, some investigators may find it useful to follow a Developmental Evaluation design. Michael Quinn Patton created Developmental Evaluation to evaluate complex, dynamic environments. The work is messy, nonlinear, and therefore uncomfortable to many investigators. Evaluators are key team members in programs employing Developmental Evaluation, since collecting, analyzing, and incorporating evaluative data is part of the program design.
It is possible to create a hybrid of Traditional and Developmental Evaluation that combines and customizes concepts from both methods so they are applicable to systems-level change.
Identifying a clear, overarching goal to the work is critical before embarking on systems evaluation. Once specified, it will be easier to determine what each sector of the food system can contribute toward that goal. From there, unique evaluation plans can be developed for each sector being targeted. Ideally, some indicators will apply to all sectors and can be collected across the board. Qualitative and quantitative data from a variety of sources should be collected and included in the analysis.
