Design First

To plan software architecture before coding, define requirements, explore architectural options, and create a design document detailing system overview, data models, and API design to align stakeholders and reduce ambiguity.

A design-first methodology for feature development is a four-phase workflow that enforces understanding problems, exploring options, detailing designs, and validating them before implementation to ensure clarity and feasibility.

Create a software design document by detailing the system overview, data models, and API design through an iterative validation process, ensuring it serves as a single source of truth for implementation and review.

Yes, the design-first workflow works for cross-functional architectural changes by guiding teams through understanding requirements, exploring trade-offs, and detailing data models and API design before committing to implementation.

You should avoid upfront design documentation when a feature requires minimal architectural changes, has low ambiguity, or demands rapid prototyping where validating directly through code implementation outweighs exploring design options beforehand.
