A walkthrough becomes a liability when users cannot tell whether it is current
Product walkthroughs are valuable because they show the interface, sequence, and context that written instructions can miss. The same visual detail also makes them vulnerable to product change. A renamed button, moved setting, new navigation pattern, updated permission model, or altered workflow can make a trusted walkthrough confusing or wrong.
The solution is not to rerecord every video after every release. It is to maintain walkthroughs as governed product knowledge. Each asset needs a clear scope, version context, accountable owner, review date, update triggers, and a defined action when it becomes outdated.
Core principle: Do not promise that every walkthrough is timeless. Make it easy to know what it covers, who owns it, when it was reviewed, and what happens when the product changes.
