When\noutcomes move, the instability may sit in the recommendation itself or upstream\nin how the evaluator associates a requirement with a vendor.\n\nThe core question is how stable recommendation outcomes are, and where any\ninstability originates. What remains open is how much variation is normal and\nwhat separates unstable requirement association from an unstable recommendation.","url":"/concepts/recommendation-stability","machineUrl":"/objects/recommendation-stability","referencedBy":[{"from":"field-vs-membership-distinction","rel":"part-of"},{"from":"E-042","rel":"part-of"},{"from":"E-045","rel":"part-of"}],"_meta":{"site":"Upstream Zero · Commercial Intelligence for AI-Mediated Commercial Evaluation","version":"0.1","note":"Claims are presented at their evidence tier; Narrated is the lowest.
