As a product manager tasked with designing a travel product for Facebook, my first step would be to conduct extensive research on the travel industry and identify the pain points and needs of potential users. This would involve gathering data on existing travel products, as well as conducting user interviews and surveys to better understand what features and functionality users are looking for in a travel product. Based on this research, I would begin to develop a product roadmap that outlines the key features and functionality of the travel product, as well as a timeline for development and implementation. This roadmap would be shared with key stakeholders within Facebook, including the design and engineering teams, to ensure that everyone is aligned and working towards the same goals. Once the roadmap has been established, I would work closely with the design team to develop wireframes and prototypes of the travel product, which would be tested with users to gather feedback and make improvements. This iterative process would continue until we have a product that meets the needs of our users and aligns with the overall goals of Facebook. Finally, I would work with the engineering team to develop and launch the travel product, which would be marketed to Facebook's vast user base through targeted advertising and other promotional efforts. Ongoing monitoring and analysis of user feedback and usage data would be essential to ensuring the continued success and growth of the travel product.
