I don't have access to the source content you referenced, so I can only work from the name and description. This appears to be a framework for organizing company operations and processes in a structured way. You'd likely use it when you need to document how different parts of your business work together or when scaling up and things are starting to slip through the cracks. The "OS" framing suggests it treats company operations like a system with defined interfaces and processes. Without seeing the actual implementation, it's hard to say if it's opinionated scaffolding or more of a flexible template, but the concept of codifying company knowledge is solid if you're tired of institutional knowledge living only in Slack threads and people's heads.
