What is spec-driven development?

Spec-driven development functions as a workflow-centric approach to software engineering, utilizing AI agents to translate well-defined specifications into code. Rather than focusing solely on tools, successful implementation requires a fundamental shift in team behavior and process, ensuring that requirements, planning, and implementation remain within a single, iterative loop. Laura Tacho, a senior principal technologist at AWS, emphasizes that software delivery remains a team sport; therefore, multidisciplinary collaboration between developers, product managers, and designers is essential to maintain alignment and avoid the pitfalls of siloed, waterfall-style documentation. While AI tools offer new opportunities to capture intent and automate documentation, the core challenge lies in balancing planning with short feedback loops. Ultimately, the future of this practice depends on creating shared organizational intelligence layers that keep intent and code in sync without overwhelming teams with unreadable, maintenance-heavy artifacts.
