Conclusions / lessons learnt

VIS process led to a set of defensible investment

recommendations and consensus among key Gavi

stakeholders

Multi-step process with many qualitative and quantitative

inputs; detailed methodology evolved in the process

Evaluation criteria formed a framework to help facilitate

comparison and prioritisation; no single algorithm can do

justice to the diverse considerations relevant for prioritisation

Critical success factors: robust evidence-base; clear decision

framework and full transparency of the process; active

stakeholder engagement and consultation; independent

expert validation of analyses

to determine relative score

eg. 120k deaths averted puts
