Thank you for this very appreciated exchange.
I'm a National Monitoring, Evaluation and Knowledge Management Officer in Senegal and perhaps my small experience can provide some responses to the two questions. New profiles are emerging and developing which combine these two missions and this is because there is a close and proved relationship between these two functions.
The GAFSP MMI (Global Agriculture and Food Security Program Missing Middle Initiative) project format I work for is a pilot. The M&E and the KM functions are important for data treatment, capitalization and workshops on lesson learned. In this project, Knowledge Management is a participatory work that includes the members of the Coordination Unit: after the coordination mission, our goal is to decide on the basis of the lesson learning and knowledge capitalization if to scale up the pilot initiative or not and in which way.
In case of bigger programs or plans composed by many project components, you need to establish a M&E and KM Department with a team composed by the Team Leader, the M&E Officer for data management, the M&E Officer for Knowledge Management and a M&E officer for data communication. More options and formats for the team composition are possible depending on the type of organization.
