Selection is the eventual outcome. Survivability\ndescribes movement through the evaluation before selection is reached.\n\nTo be recommended and stay recommended, a vendor has to survive a series of\ngates: getting surfaced, passing screening, holding up in a comparison,\nclearing validation, and making the final cut. Each requirement a buyer adds\ncan change who remains, which is what the experiments below record.\n\nThe part we can measure today is survival as requirements are introduced in\nsequence. The fuller notion, holding up under re-sampling, newer models, and\nrepeated follow-up, is not yet a settled measurement; that sits behind our\n[evidence method](/concepts/evidence-tier) and the open M-1 question. We keep\nthe term here so the site does not lean on a word it cannot yet fully define,\nand we report what we can defend at its tier.","url":"/concepts/recommendation-survivability","machineUrl":"/objects/recommendation-survivability","referencedBy":[{"from":"category-dependent-survivability","rel":"part-of"},{"from":"field-vs-membership-distinction","rel":"part-of"},{"from":"E-034","rel":"part-of"},{"from":"E-040","rel":"part-of"},{"from":"E-041","rel":"part-of"},{"from":"E-043","rel":"part-of"},{"from":"E-044","rel":"part-of"},{"from":"E-045","rel":"part-of"},{"from":"competitor-displacement","rel":"part-of"},{"from":"frontrunner-movement","rel":"part-of"},{"from":"recommendation-set-formation","rel":"part-of"},{"from":"recommendation-stability","rel":"part-of"},{"from":"validation-and-evidence","rel":"part-of"},{"from":"vendor-elimination","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.
