Abstract
In 1988 the African Development Bank Group decided to adopt the logical framework approach (LFA) in relation to the design, implementation and estimation of effects of projects. By January 1993 the use of LFA was mandatory. Post-evaluation reports would be based on retrospective logical framework matrices using data contained in the original appraisal reports. Between February 1993 and May 1995 health- sector projects were post-evaluated in seven countries. There were conceptual problems with this retrospective application, as well as problems concerning the definition of assumptions and required observable verifiable indicators. Difficulties with the collection, collation and use of data are reviewed and emphasis is placed on the importance of the Health Management information System as a planning and management tool.
