We looked at population penetration, privacy and effectiveness of an app to arrive at a 'Viability Rating'. A 3-point colour coded scale was used to grade each criteria.

At @TakshashilaInst, we use the reverse bollywood format, so let me start with our recommendations.
2/n
1. Solutions should not be deployed in ways that can cause exclusion/denial of rights and/or privileges.
2. Inequity of internet access needs to be addressed in any future stimulus/recovery package (we even mapped some of our estimates).3/n
3. Effective legislation and the use of privacy preserving models are a must.
4. Mass rollouts must be preceded by proofs of concept.

And, here's some detail on the criteria and scoring.

4/n
We did this for a total of 30 apps (Indian and International) across 5 use-cases:
> contact tracing

5/n
> quarantine management

6/n
> risk determination

7/n
> information

8/n
> e-passes
9/n
