6 different types of requirements documentation
Requirements Documents are used to accurately and unambiguously convey the needs of a business. A business requirements document is a well-known “requirements” document; however, there are other types of requirements documents that are also important to moving a project through to completion. The template of a requirements document to use depends on the type of requirements that you intend to capture. Organizations develop and adapt their own templates to meet their needs.
Business Requirements Document (BRD)
Define the high-level business goals and core functions of a product. Prepared by a business analyst or project manager. Contains sections to describe the project scope, functional, non-functional, data, and interface requirements. Provides a good understanding of user types and their expectations. It presents an idea of the proposed system from the point of view of the business organization commissioning the system.
Functional requirements document
It describes in detail the services provided by the system. Specify the sequence of events, inputs, outputs, stored data, and computational processes for each function. Capture system behavior for every user event and action. Text descriptions are supported by wiring diagrams for better understanding.
Quality requirements document
This document describes the final product acceptance criteria. It establishes what end users expect from the system in terms of performance, response time, reliability, disaster recovery, failsafe mechanisms, maintainability, accessibility, load handling capacity, portability and robustness. These are also called non-functional requirements.
Technical requirements document
The software, hardware, and platform requirements for the final product are described in this document. The software requirements establish in which programming language the system must be developed, what software will be used to access the system, and the type of database. The hardware requirements establish the processor speed, memory size, disk space, network configuration, and the capacity of database and application servers that will be deployed when the system is up and running (desktop environment). production). The platform requirements establish the limitations of the system environment and the limitations of the technology that will be employed during the construction of the system. If the system is to be deployed in multiple locations, the hardware and software environment for each location is described. The document lists the limitations that must be considered when designing the system architecture.
User Interface Requirements Document
Describes the appearance of the system’s graphical user interface (GUI). Defines the positioning of user input fields, messages, menus, header and footer on the application screen. It explains how the user will access the screens and the sequence of user actions for each process. Contains mockup screenshots to give the project team an idea of what the final product will look like. Sample:
• How the content is presented to the user
• Color codes to be used
• User navigation
• Hints / tips / hints that will be displayed to the user on the screen
• “Save data and continue operation later” options when the user has to enter a large amount of data into the system
Shortcut keys for frequently used functions
Market Requirements Document (MRD)
Defines the needs of the end user of the system (that is, the customers of the company for which the system is to be implemented). This document has been prepared by marketing managers, product managers, or business analysts. Define the system functions according to the current market trend and the expectations of the target customer base. List the characteristics that give the company a competitive advantage in the market.
