Why do you "HAVE" to conduct a meeting? Who is forcing you to do this? As you have no clue about this meeting, it sounds like it is not necessary, or you wouldn't asking us. If you manager has told you this, then ask him what you should be discussing. None of us work for your organisation.
Millions of man-hours are wasted annually around the world with useless meetings. You wonder why no work gets done and staff are not coping with work loads? It is because they are tied up in useless meetings called by managers who have nothing better to do with their time.
Only call a meeting when it is necessary. Circulate an agenda of the items to be discussed, set a time limit, and get it over and done with quickly. Meet in a room with no chairs. Standing up meetings move much faster and focus people's minds on the job at hand.
You don't need a meeting to impart basic information, just send them a memo or an email, and let them get on with their work. They will thank for being considerate of their time and workloads.
