The document introduces Outcome Mapping, a method for planning and assessing social change projects. It was developed in the 1990s as an alternative to traditional logical framework and results-based management approaches. Outcome Mapping focuses on influencing boundary partners' behaviors rather than attributing impact. It defines progress markers to track non-linear changes in partners over time. The method has been used successfully by organizations like VECO and St2eep to integrate monitoring and evaluation into project planning and promote learning.
