Deciding on the intervention logic (project logic)

The intervention logic is the cause-and-effect chain or results chain that’s been identified in the Performance Framework:

• You gather the necessary resources (human resources, materials, equipment) and funds
• With the resources, you can organise the activities
• The activities produce outputs: goods, services, knowledge, information, etc. These are the immediate results.
• When these outputs are used, they lead to effects or intermediate results.
• The effects contribute to the final results, or impact.

This information is presented in the logical framework (first column, except for the resources).

Note that compared to the ‘classic’ logical framework as it is used in LFA and PCM, there is a dimension of time in the intervention logic of RBM, as well as a spatial dimension. We immediately get the outputs as a consequence of the activities. But it takes time for the effects to materialise (near the end of the project or maybe even after it) and the impact will only be visible after a long time (sometimes years or even decades after the project). The outputs will be used directly by the people involved in the project, while the effects are generally felt by those people and their immediate surroundings (family, clan, village). The impact on the other hand may be visible in a widespread area (region, country, internationally).
