Technical Reference & Key Concepts

Design Doc Structure

  1. Context & Motivation: Why are we doing this? What problem are we solving?
  2. Goals & Non-goals: What is in scope? What is explicitly out of scope?
  3. Proposed Design: Architecture diagram, data flow, API surface.
  4. Alternatives Considered: 2-3 alternatives with tradeoffs. Show you explored the space.
  5. Scaling & Risks: How does this break at 10x traffic? What are the failure modes?
  6. Test Plan: How will you validate this works in production?

Explaining Complex Concepts:

  • Start with the analogy (e.g., "a load balancer is like a restaurant host").
  • Follow with the definition (precise technical description).
  • End with a concrete example ("So if server A is overloaded...").
