Software requirements describe what a product should do, which rules it must follow and how well it should work. Requirements management means agreeing on these needs, keeping them up to date and linking them to code and checks. You can start with one feature and one developer. The goal is to keep important decisions available after the conversation ends.
Requirements management is often seen as paperwork that takes time, slows releases and matters only in regulated industries. In the era of AI coding, it is a practical way to guide agents and keep a project under control: stay focused, preserve product context and prevent architecture drift. The same AI can help with the upkeep by drafting updates, finding inconsistencies and maintaining links to code, reducing the routine work involved.
