As a product manager thinking about launching FB Events in 2011, I would set up several metrics as goals for my team. These metrics would focus on user engagement and adoption, as well as revenue generation. First, I would set a goal for the number of users who create events on the platform on a monthly or weekly basis. This would be a key indicator of user engagement with the product. Second, I would track the number of users who RSVP to events on a regular basis. This would help me understand how well the product is resonating with users and how likely they are to actually attend events. Third, I would set a goal for the number of events that are successfully created and shared on the platform, as well as the number of attendees per event. This would help me understand the overall impact of the product on the event planning and attendance industry. Finally, I would track revenue generated by the product, either through direct sales or through advertising revenue generated by event promotions. This would help me understand the long-term sustainability of the product and whether it is meeting the needs of both users and advertisers. By tracking these metrics, I would be able to identify areas for improvement and optimize the product to increase user engagement, adoption, and revenue generation over time.
