Summary

1. Resources for SGS are limited, so it is important
   to develop an epidemiologically driven process
   for prioritizing what type of data
   collection/analysis to do in which groups in
   which areas
2. Collecting all types of data everywhere is not an
   effective use of resources
3. The PSA can be reframed as part of staying AHEAD,
   specifically by
4. Defining geographic units
5. Assessing what is known
6. Prioritizing further which data to collect
