A memorable event name is short, meaningful and sticks. Four ingredients:
Method: start with a DNA session and pull out the keywords that carry your brand. Combine those with the occasion for the event and the feeling you want to leave behind. Draw up a longlist of 30 to 50 names. Cut everything a random competitor could use too. Keep five. Test them out loud on colleagues who aren't working on the event. The name people repeat straight away wins.
Avoid years in the title, because then your communications date. At Live Impact we develop event names through a rhetorical session we call the slogan-architect.
