Abstract
To assess the functionalities of NEDSS-compatible systems, we utilized the development of cultural models which is part of a technique called contextual inquiry. We obtained several cultural models, each restricted to data sources and interviews of CDC programs (users of NND data) and public health jurisdictions (reports NND data). The models highlighted factors that otherwise would be difficult to capture or represent yet still has an operational impact on the system user. This approach may be adapted for other evaluation efforts.
