A substantial part of the evaluation is a process analysis. This type of assessment focuses upon basic organizational and management processes. The key issue is the extent to which the processes in place support the goals of the activity. Most process analyses have a qualitative focus and involve document review, interviews and focus groups. Hence, they are non-experimental in structure.
All program evaluations benefit from the use of experimental parameters.
However, in the case of the Lilly Project, the decision was made that the most feasible approach, given the nature of the process and the type of data required, was nonexperimental.
