Big Design Upfront
Big Design Upfront (BDUF) is a software development methodology where comprehensive planning, design, and documentation are completed before any coding begins. It emphasizes creating detailed specifications, architectural blueprints, and requirements to minimize changes during implementation. This approach aims to reduce risks and ensure alignment with project goals from the outset.
Developers should use BDUF in projects with stable requirements, high regulatory or safety-critical needs, or large-scale systems where upfront clarity is essential, such as in aerospace, finance, or government sectors. It helps prevent costly rework by establishing a clear roadmap early, but it can be less flexible for dynamic or rapidly evolving projects where agile methods might be more suitable.
