Having a good event is one of the most important things for a product marketing. This is a great way to expose our product to new customers and to make them smile about our product.
BUT! this is such a hard work for product marketers. There are so many questions you need to take care of like followings before that.
What kind of event would be the most effective under what situation and we need to prepare for the event for what target users. How much budget you have? What design and development should be coming along with the event? What kind of reward we need to prepare? How are we going to pay for the reward?
If you have one board where you can put everything related to this event, you can brainstorm with your maximum imagination first, then you can organize and share the outcome for your team.
