• Curation level: module_curated

Learning objectives

• Explain Identifying the Hard Parts as a structured reasoning process involving requirements, constraints, bottlenecks, and tradeoffs instead of disconnected interview heuristics.
• Use Identifying the Hard Parts to move from vague system goals to a defendable design with explicit assumptions and failure boundaries.
• Use fundamentals-of-software-architecture, system-design-primer to connect the learner-facing explanation to capacity planning, architecture sketches, and production-oriented tradeoff analysis.

Prerequisites

• Comfort with architecture, databases, networking, and distributed-systems tradeoffs from the earlier semesters.
