Protocol: How to coordinate the greeting procedures at a business event (commentary in Dutch)

How to operate when the CEO (as host of a business event) wants to welcome every guest in person (and when this CEO wants to know who is who).
In this case, the employees of the company function as co-host. They await the guests in a reception area and each greet a number of guests, after they welcomed by the host.

The role of protocol officers:
Protocol officers inform guests upon arrival: by whom will they be welcomed? Then they announce the guest to the host, by name and function.
Furthermore the protocol officers will prevent queues, so people do not have to wait.
After the welcome by the host, guests are escorted to one of the co-hosts in the reception area. Guests are again informed: to which co-host will they be brought. And the co-hosts are told: what is the name and function of the guest.
