When several teams contribute to a knowledge site, the pages that greet new visitors often end up owned by no one in particular. A getting-started guide might reference articles from three different teams, but when one team updates or removes a piece, the introductory page still points to the old version. The first step is to identify which team is responsible for each introductory page and which teams own the content those pages link to or summarize. A simple table listing the page, its owner, and the upstream content it depends on gives every team a shared reference they can check before making changes.
Ownership alone does not prevent drift. A useful practice is to attach a short dependency note to each introductory page that names the specific sections or articles it draws from. When a contributing team plans to revise or retire one of those sections, the note tells them who to notify. This does not guarantee that every change gets caught in time, but it gives teams a concrete place to look rather than relying on memory or chance.
For the review itself, tie it to actual content changes rather than a fixed calendar schedule. If a team publishes a major revision to a core article, that is the moment to check whether any introductory page summarizes or links to it. A quarterly review can still serve as a backstop for slow-moving content, but event-driven checks catch problems closer to when they appear. Each team can decide what counts as a major revision based on their own editorial standards.
When drafting or updating introductory content, keep the language at the level of what the page actually does for the reader. Instead of describing the site's history or organizational structure, state what a new visitor will find and in what order. This makes the page easier to maintain because it only needs updating when the reader's path changes, not when internal team names or reporting lines shift. It also makes handoffs between teams simpler, since the page's purpose is defined by reader need rather than by who happens to own it at a given time.
