Low Level Design Review
Low Level Design Review (LLDR) is a software development process where detailed technical designs are systematically examined by peers or stakeholders before implementation. It focuses on evaluating the architecture, algorithms, data structures, interfaces, and code-level decisions to ensure correctness, efficiency, and maintainability. This review aims to catch design flaws early, reducing rework and improving software quality.
Developers should conduct Low Level Design Reviews when transitioning from high-level requirements to detailed implementation plans, typically after system design but before coding begins. It is crucial for complex systems, safety-critical applications, or projects with multiple developers to ensure technical consistency and avoid integration issues. Use cases include reviewing database schemas, API contracts, class diagrams, or algorithm specifications in agile sprints or waterfall phases.
