What gets lost when a shift changes?
A guest asks for towels. Someone replies that the request has been received. Later, the next shift sees the reply but cannot tell whether housekeeping delivered them. The missing detail is the state of the work, not the existence of a message.
Review your current handover process for this kind of uncertainty. Which requests depend on another department? Which promises are only in someone's memory? Which conversations look finished because they received a polite acknowledgement?
Agree on plain status descriptions your team can use, such as received, assigned, waiting for an update and completed. These are proposed operating labels. Use the controls your inbox actually supports and add a clear note where a separate state is needed.
