Criteria for deciding on prototypes to develop

Criterion	Description
Contextual appropriateness	The idea should align and be seen to align with the cultural, political norms and expectations in the context where the intervention is to be developed
Feasibility	The ideas can potentially be developed easily and practically with resources that are readily available in the context in which it is to be developed.
Cost	Developing the idea should have a reasonable cost, given the available budget and the context in which the resources would be developed.
Flexibility	Resources developed using the idea could be used or changed in different ways, e.g. by inserting or removing parts without causing a lot of problems.
Replicability	It should be possible to replicate the development of the resources without losing important attributes and information
Transferability	To the extent possible, the resources or parts of the resources developed from the idea should be able to be used in other contexts without much difficulty.
Self-reliant	Using the resources developed from the idea should depend on having other resources, e.g. regular support from health workers or teachers.
Scalability	It should be possible to use the resources on a wider scale
