Intervention

Once you have defined the theory of change for your intervention, you have to determine how you will implement your intervention. This guide focuses on tech-enabled interventions.

Modules

In order to implement the intervention, you have to identify the module at each level, i.e., the piece of the puzzle, required to enable the intervention.

For instance, the farmer advice intervention would have the following modules:

	Level	Module
1	Context-aware advice will be made available for farmers	Recommendations Engine
2	Farmers will access the advice	Whatsapp Bot
3	The advice will influence farmer behaviour	Farm Inputs Data Collection
4	Farm yields will improve	Farm Outputs Data Collection

Feature in an app, vs entire app

Your intervention could be a feature in an existing app, or it could be an entirely new app/interface. For instance, the intervention in the example above uses Whatsapp as the interface. Alternatively, the feature could have been a chatbot in an existing mobile app. Either way, levels 3 and 4 have to be considered and measured the same way because they are a consequence of the intervention.

AI vs non-AI

Just a question of "how"
