How do you maintain a Wikipedia page over time?

A Wikipedia article that was created well three years ago is not a Wikipedia article today; the platform’s nature requires ongoing maintenance. Several streams of work keep an article current. Monitoring through WikiAlerts™ captures every edit as it happens and allows for fast response. Periodic article review identifies content that has gone stale (a former CEO still in present tense, an outdated financial figure, a company description that no longer matches the current business). Disputes that arise – a contested claim, a contentious editor, an NPOV concern – get engaged through Talk-page discussion that cites the applicable policy and proposes a policy-compliant resolution. And the structured-data layer (Wikidata, the linked language versions) gets maintained in parallel, since drift across that layer propagates into Knowledge Panels and AI engines. Done continuously, the article stays accurate. Left alone, it drifts.
