Only 2, with IRL examples from this month: * The ability to challenge a proposal and figure out you don't need "an xxx with yyy but just a zzz should be enough" F.e. merging seperate repos to monorepo, simplifying development & CI/CD enormously for a tiny team. * The ability to understand which solution matches best with your whole context (environment, capabilities, skillset, risk, ...) Don't go for integrating a rules engine in an MVP with a tight deadline, but just setup a monthly alignment between Product owner & back-end dev.
