A software specification establishes a shared source of truth covering objective, scope, constraints, and acceptance criteria. It reduces ambiguity by codifying six core areas including project structure, code style, testing, and boundaries before coding begins.

The best way to plan architectural changes with unclear requirements is applying a structured specification process. It guides architectural decisions by defining objectives, boundaries, and testing strategy early, establishing a shared source of truth.

You break down a major feature by outlining the objective, commands, project structure, code style, testing strategy, and boundaries in a spec. This template guides the engineering workflow and clarifies success criteria for each development task.

Yes, spec-driven development works for coordinating changes across multiple modules. It applies structured specifications to major features, ensuring shared success criteria and boundaries are established across intersecting project components.

You should not use a structured specification for minor updates or isolated fixes where requirements are already clear. It is designed for new projects, major features, or architectural changes demanding coordinated cross-module planning.
