A Business Requirements Document (BRD) is a formal document that outlines the essential requirements and expectations for a project or initiative. It serves as a guide for stakeholders, ensuring that everyone has a clear understanding of the project's goals, scope, and deliverables. The BRD typically includes details about the business needs, objectives, and any constraints that may affect the project. The BRD is crucial for effective communication among team members, including project managers, developers, and clients. By providing a structured framework, it helps to minimize misunderstandings and ensures that the final product aligns with the initial vision. This document is often used in conjunction with other project management tools and methodologies.
