You can start your planning by working through these questions:

• Why do you want to have an event?
• What is the aim of this event? What do you want to achieve?
• Who is the event for? Whom do you want to benefit or reach?
• What are their needs or interests?
• How will you know that the event is a success, the aims have been achieved, the needs met? Be specific - what will it look like, what will people say, how will they be reacting?
• What features would your successful event have?

Result

You should now be able to draw up an outline for 'what' your event is; including the subject or topic you will engage with, as well as the kind of activity and the format your event will have.
