Draw an UCM Using UCM, model the scenario where the meeting scheduler system receives a meeting request from the meeting initiator, checks availability of important participants on the requested date, then availability of requested meeting location. If important people are not available, the meeting scheduler system rejects the meeting request and ask for a new range of dates. If the requested meeting location is not available, the meeting scheduler system recommends other available locations and wait for the approval from the meeting requester. If the dates and location are available, the meeting scheduler system sends a confirmation to the meeting initiator.
