AI speeds up coding, not delivery. What actually gets faster, where a software estimate really goes, and how to set a timeline you can take to your board.
AI-Assisted Development
Most AI workflows treat the code as if it were the theory. On a brownfield system it is not. Codebase archaeology is the discipline that produces the written understanding an agent needs before it edits.
An AI coding agent will write confident code against assumptions it invented. On a 12-year-old codebase, that is where the bugs come from. What the agent has to understand first, and how to brief it.
