Table 7. Initial Definitions of Operational Readiness Levels for Disease Prediction Models.

Level	Definition
1	Research only reported on observed information
2	A constructed model which has yet to be applied to data (or The model theory has been developed based on observed or hypothesized information)
3	The model has been created but has not been validated
4	The model has been verified and validated
5	The model has been demonstrated as useful but for only its original location (pathogen or population) and is still being updated to accommodate additional locations
6	The model has been demonstrated as useful in both its original location (pathogen or population) as well as an independent location (pathogen or population), but not all requisite locations
7…n	Further study is needed to explicitly delineate the criterion for all levels.
