A functional requirements document is critical in the development of an information system because it thoroughly outlines the expected functionalities and delivery methods that the system needs to meet. This document serves as a foundational communication tool among stakeholders—including developers, project managers, and users—by detailing what the system should do. It specifies functional needs, describing features, interfaces, and user interactions, ensuring that all parties have a clear understanding of the system's objectives and requirements.

The clarity provided by this document helps avoid misunderstandings and scope creep during the development process, as it sets specific expectations for the project. Stakeholders can reference this document throughout the development lifecycle to ensure that the delivered system aligns with their needs and requirements. Additionally, it aids in testing and validation, as the fulfillment of the functional requirements can be assessed against the stated objectives.

While other documents, such as technical specifications and design documents, are also important during the development process, they focus on different aspects of the system. For instance, technical details of implementation pertain to coding and architecture, and while those aspects are crucial, they follow the establishment of functional requirements. The functional requirements document serves as the starting point for these other documents and is essential for guiding the overall development effort.
