I am researching for effective models and approaches to deliver effective and sustainable improvements. Consulting by experts to identify and solve problems, projects to deliver services to the unserved, training of healthcare professionals, etc. are some of the donor-funded activities being implemented in developing countries. However, their effectiveness and sustainability are in often in question as well as the effective impact of international multilateral, bilateral, non-governmental and charitable organizations. What standards need to be met to demonstrate effectiveness, efficient use of all resources available and sustainability?
