As the product manager for OpenTable, the worst post-booking experience that we would need to address is when customers arrive at their reserved table, and it is not available. This can happen due to multiple reasons, such as the restaurant may have given the table away to another party or may have overbooked reservations. To solve this issue, we can implement the following solutions: 1. Real-time table status: We can work with the restaurants to provide real-time updates on the availability of tables, which customers can view before arriving at the restaurant. This would help customers avoid any unpleasant surprises and provide them with the flexibility to change their reservation if required. 2. Confirmations and reminders: We can send customers confirmation emails and reminders leading up to their reservation to ensure that they are still planning to show up. Additionally, we can remind them of the importance of being on time and updating their reservation if their plans change. 3. Incentives for restaurants: We can offer incentives to restaurants that have a high rate of on-time table availability to encourage them to prioritize reservations and ensure that tables are available to customers who have made reservations. 4. Customer service: If a customer arrives at a restaurant and finds out that their reserved table is not available, we can provide them with immediate support and assistance to find an alternative option. This could include finding another restaurant nearby, offering a discount on their next reservation, or providing them with a credit for their inconvenience. By implementing these solutions, we can work towards ensuring that our customers have a positive post-booking experience and continue to use OpenTable for their dining needs.
