Solutions for emerging and epidemic diseases, like AIDS, tuberculosis, and malaria.
Health technologies designed for low-resource settings, by the people who will use them.
Safer childbirth and healthy children. Health equity for women, among the world’s
most vulnerable—and influential—populations. The basic protection of vaccines for women
and children around the world.

How is PATH organized? Global Health projects managed either by global programs or by field programs.
ICTG housed in Technology Solutions
but consults to all field and global
programs

Health Information Complex, crowded field; many donors; disease-
focused M&E; fragmentation; epidemic of indicators
Lack of comparability, need for certification and application of common standards
Weak analytical capacities; health poorly connected to statistics;
Translation of health data into information for policy action; evidence-based decision making
Paris Declaration on Aid Effectiveness; harmonization and alignment

What do we mean by “architecture”?: There are distinct phases of ICT development that our process will follow.
• Architecture is grounded in user analysis, requirements and systems design grounded in the situational context.• Solutions (by design) will need to be scalable past discrete pilot projects and integrate with country HMIS.
