    "This is a Measure Success question with a slight twist. The twist here is we need to consider a hypothetical changes rather that one already built. This changes our formula slightly - specifically we may not be able to apply a UX flow to drive analysis since we're unsure of the implementation. Instead, we'll look at core behaviors that are indicative of success. Here's the modified formula: Ask clarifying questions State the goal of the feature **Apply a UX flow to drive a"

    "To improve the passenger experience at a major metropolitan airport, I would focus on streamlining the pre-arrival, arrival, and post-flight stages of their journey. Pre-arrival, we could integrate flight details into the Uber app and provide predictive ETAs to help passengers plan better. At the airport, we could partner with authorities to create dedicated drop-off and pickup zones, along with clear in-app navigation to reduce confusion. Post-flight, we could implement dynamic pickup zones, vi"

Cool so this is the rough backbone structure that we can follow and ofcourse we can add meat later on to it and pivot if required.
