What level of attrition should I account for?
Edited
It is essential to account for 50-70% attrition for your Tech Week event.
Please keep in mind that because these are mostly free events (and a lot of the people signing up are out of your immediate network), there will be a lot of attrition at these events. Use your best judgment here and make sure you’re accounting for attrition and invite more than you think you have capacity for! A good rule of thumb is to account for 50-70+% attrition, depending on:
Location
Weather
Speakers
How much or little pre-marketing or attendee comms you’ve done.
