-- A lot of what the MNOs are looking for historically has depended upon what the perceived needs of Dash as a greater DAO are, what Dash Core Group is working on on our behalf, what the relative price of Dash is at, how large our treasury is, what other proposals or carry-over/multi-month proposals will need continued funding from previous cycles, like @Red
said how far along the realization of a proposal is, of course the ROI (though this is difficult to measure in some cases, or varies depending upon what the project intends to or is capable of delivering), how engaged the proposal owner(s) is/are with the community, how well they receive and adapt to feedback, what kinds of opportunities the proposal opens up for further enrichment or enhancement of the network, the reputation or history of the proposal owners and their perceived ability and likelihood of being able to carry out their proposal, how popular the proposal is with other MNOs, really just a ton of factors.
Because almost anything *could* be funded by the DAO, we have to be ready to assess the merits of every project individually, and once we've done that, weigh them against each other in how the budget is allocated. Not every MNO follows that same process or cares about the same things or uses the same algorithms, but those are just the factors that I've observed holding the most sway over voting over the years.
One of the projects we funded, Dash Watch ( https://dashwatch.org/
) has done a fantastic job helping not only to vet the veracity of proposals and proposal owners, but to help us determine their value to the network. One of their initiatives lately has been to work with the proposal owners to define what each proposal's metrics of success look like in more objective or quantifiable ways, in order for us to determine whether or not their project is something it would be reasonable/beneficial not only to fund, but in the case of multi-month proposals continue to fund. This too, as I understand it, will be built in to the Nexus platform as well, as DashWatch has been working closely with the Nexus developers.
