Don't Assume the Happy Path

In this segment, we focus on a common issue often seen with more junior engineers - Only considering the happy path when designing systems. Here’s the core points from the video:

  • As engineers, our goal is to design systems that work reliably even when things go wrong. A system that fails 1% of the time is often unacceptable

  • We need to anticipate and design for potential issues, not just ideal scenarios

  • Proactively identifying weaknesses and planning solutions demonstrates strong engineering skills and foresight

  • Documenting our design and potential problems as we go helps manage complexity and ensures we address edge cases effectively

  • We go through a detailed example of all this with a ride-sharing system design problem
