The ARISE team developed an analytical framework to guide the in-depth studies.  The framework began with a logic model of the routine immunization system, then hypothesized that drivers of performance could intervene at the various and possibly multiple points along the pathway to RI performance.  The in-depth case studies looked in detail at the district level to identify drivers of change, and describe and analyze how these drivers intervene with the immunization system to stimulate or accelerate improvements in RI coverage.  ARISE also looked at how drivers behave and interact in different contexts.

Context was defined as “those things that are outside the direct influence of the immunization system — including health system factors.”
