Meeting room scheduling guides

The same handful of questions about meeting rooms has circulated on IT forums for over a decade, and most of them never got a complete answer. These guides answer them properly — including the parts where the right answer is "configure what you already have" or "buy a category of product we don't sell".

Who writes these: Puresoft Ltd, the maker of Meet Me At Work, a QR-code meeting-room booking system. Where our product is relevant we say so in a clearly marked section; the rest of each guide stands on its own and cites primary sources.
