Thanks for the post, Lizka! I have thought for a while that estimating the cost-effectiveness of (concrete) interventions is strictly better than assessing (abstract) sets of interventions with the ITN framework.
The product between importance, tractability, and neglectedness is supposed to be equal to the cost-effectiveness. So I prefer to model cost-effectiveness based on the parameters which are better defined, and are easier to quantify accurately for the intervention under assessment instead of always relying on the same 3 factors of ITN.
I also like that cost-effectiveness analyses focus on concrete interventions. The ITN framework is often applied to get a sense of the cost-effectiveness of sets of interventions, but there is often significant variation, so the results are not necessarily informative even if they are accurate. To learn more about the cost-effectiveness of a set of interventions, I prefer estimating the cost-effectiveness of interventions which I think are representative, account for a large share of the overall funding, or have the chance to be the most cost-effective.
