Most vendor briefings open with the same company-overview deck no matter who is on the call. The IIAR's own best-practice paper on running one says the majority of analyst briefings are poorly planned and fail to meet their objectives, when an objective was set at all. Most correction requests get sent the same way too, regardless of what kind of claim was actually wrong, a headcount confused with a competitive ranking.
Bellhaven Systems, a fictional identity and access management vendor, gives this pack its worked example: three analysts at three firms, tracked across fourteen months. Nine published inaccuracies got logged and tagged the day each was found. Six were factual, a headcount, a stale price, a feature marked unsupported two years after it shipped, and every one, requested with a dated source attached, landed in that analyst's next relevant publication. Three were opinion-shaped, a tier assignment, a ranking with no benchmark cited, a call that a roadmap was thin.
Those three got requested the same way, with the same promptness, by the same contacts, and none of them landed, which is the split the type of claim predicts rather than any one relationship. Forrester's own policy admits as much. It will correct material errors quickly once it finds evidence of a factual mistake, while a vendor's evaluative pushback on a Wave score will not get the vendor removed from the evaluation at all.
