Problem Decomposition and Incremental Development Questions

Covers the ability to break complex, ambiguous problems into smaller, well defined components and then implement solutions iteratively. Includes techniques for identifying root causes versus symptoms, structuring analysis frameworks appropriate to the problem type, and mapping dependencies and interfaces between components. Emphasizes starting with a simple working solution or prototype, validating each subcomponent, and progressively adding complexity while managing risk and integrating pieces. Candidates should demonstrate how they prioritize subproblems, estimate effort, choose trade offs, and use incremental testing and verification to ensure correctness and maintainability. This skill applies across algorithmic coding problems, system design, product or business case analysis, and case interview scenarios.

You are tasked with building a compact security automation platform for triaging alerts, enriching them with context, and routing them to the right owner. How would you start with a minimal viable workflow, and what interfaces or integrations would you design so it can scale safely?
