A Functional Requirement Document (FRD) is a document used by business analysts to describe the detailed functional requirements of a system or software application. It outlines the specific functions, features, and capabilities that the system should possess to meet the needs of its users and stakeholders.

**Key components and characteristics of a Functional Requirement Document include:**

**1. Introduction:** The FRD begins with an introduction that provides an overview of the system and its purpose. It explains the context and sets the stage for the functional requirements that will be detailed in the document.

**2. Scope:** The document defines the scope of the system, outlining the boundaries of its functionality. It helps stakeholders understand what is included and what is excluded from the system's scope.

**3. Functional Requirements:** The FRD presents a comprehensive list of functional requirements, describing the specific actions, behaviors, and operations that the system must perform. These requirements define how the system should respond to user inputs and events. They cover tasks, processes, calculations, data manipulations, and interactions with external systems.

**4. Use Cases or User Stories:** Use cases or user stories provide detailed scenarios that describe how users will interact with the system to accomplish specific tasks. They illustrate the desired flow of events, including inputs, outputs, and the expected system behavior. Use cases help ensure that the system meets user needs and supports their intended workflows.

**5. Business Rules:** The FRD captures the business rules that govern the system's behavior. Business rules define the logic, constraints, and decision-making processes that guide the system's operations. They ensure that the system behaves in accordance with the business policies and requirements.

**6. Data Requirements:** The document outlines the data requirements of the system, specifying the types of data that need to be captured, stored, processed, and presented by the system. It defines the data structures, formats, validations, and relationships required to support the system's functionality.

**7. System Interfaces:** The FRD describes the interfaces that the system needs to interact with, such as external systems, databases, or third-party services. It outlines the integration points, data exchange formats, protocols, and security requirements for these interfaces. 

**8. Performance and Quality Requirements:** The FRD may include performance and quality requirements that define the desired performance characteristics, response times, throughput, availability, and other quality attributes expected from the system.

The Functional Requirement Document provides a detailed blueprint of the system's functionality, ensuring that the development team understands and implements the desired features and behaviors. It serves as a reference for developers, testers, and stakeholders throughout the software development lifecycle, guiding the design, development, and testing efforts.
