WELCOME to the HEAF Project that is concerned with collaborative development of a HEALTH ENTERPRISE ARCHITECTURE FRAMEWORK (HEAF) for low resource settings using a bottom-up, implementation-driven approach. The project comprises several sub-projects, including the framework itself (HEAF), the Enterprise Architecture Projects (HEAP) and the Repository of Tools (HEART). Our general approach is to post working material to the collaborative Wiki and from there, generalize to the emerging framework.
The relationship is further expanded in the Position Paper, below
