Answer
Grouping is the first mechanical hurdle. A tool that only lets someone search free text will miss the connection between a ticket describing a job abending overnight and an earlier ticket describing the same job running slowly the week before, so buyers should ask specifically how the platform links related tickets, whether by tagging, linked records, or a recurring-issue field that gets set deliberately rather than inferred.
Documentation quality matters more than documentation quantity. A short, accurate root-cause note that explains what actually broke and what fixed it is worth more than a long ticket history that never distills into an answer. Buyers should ask whether the platform makes it easy to convert a resolved ticket into a reusable knowledge article without duplicating the writing effort, since teams that have to write the same explanation twice tend to stop doing it. Post-incident review should also feed back into monitoring and PTF planning where relevant, since a recurring issue tied to a known IBM PTF or a specific software version fix is a different kind of prevention problem than one caused by a process gap or a training gap.
