A Simple Requirements Checklist That Prevents Build Confusion

Most bugs and delays do not come from complex code. They come from unclear requirements. A feature looks simple at first. Then questions appear during development. Then testing fails. Then rework starts. This guide shows a simple way to write requirements so developers and testers stay aligned. Full guide + resources. Below is a practical checklist to apply immediately. What actually causes requirement confusion Most teams already write functional requirements. Example: User can reset password That part is clear. But what is missing is behavior. How fast? What counts as success? What happens under load? This is the difference between functional and non functional requirements.
