The Big Idea#

The transition of LLMs from individual coding assistants to team-wide engineering tools requires treating prompts as first-class, version-controlled artifacts. We are shifting from ad-hoc interactions with AI to a structured workflow where prompts demand abstraction-first thinking and dictate business alignment.

[Structured-Prompt-Driven Development (SPDD)] · Wei Zhang and Jessie Jie Xia · MartinFowler.com While LLM coding assistants have proven valuable for individual developers, scaling their impact across engineering teams requires formalizing how we interact with them. Thoughtworks’ internal IT organization has developed a workflow called Structured-Prompt-Driven Development (SPDD), which treats prompts not as ephemeral chat logs, but as first-class engineering artifacts stored alongside code in version control. By formalizing prompts, teams can better align generated code with actual business requirements. However, this shift demands a change in engineering muscle; developers must index heavily on “abstraction-first” thinking, continuous alignment, and rigorous iterative review rather than relying on the LLM for architectural direction. Practitioners navigating the messy transition from “AI as a toy” to “AI as a predictable team multiplier” should read this to see a concrete, version-controlled approach to prompt management.
