The Logical Framework Approach (LFA) is a methodology mainly used for designing, monitoring, and evaluating international development projects.
[2] It has been widely used by multilateral donor organizations, such as AECID, GIZ, SIDA, NORAD, DFID, SDC, UNDP, EC and the Inter-American Development Bank.
The rows represent types of events that take place as a project is implemented: Activities, Outputs, Purpose and Goal (from bottom to top on the left hand side — see EC web site under external links).
The "Assumptions" column is important in clarifying the extent to which the project or program objectives depend on external factors, and greatly clarify "force majeure" which are out of control of the project delivery partners — an area that was of particular interest when the Canadian International Development Agency (CIDA) at least briefly used the LFA as the essence of contracts.
