Functional VS Non-functional Requirements (With Examples)

Introduction In software development, clear and well-defined requirements are crucial to the success of any project. These requirements are typically divided into two categories: functional and non-functional. While both are essential, they serve distinct purposes in shaping the final product. Functional requirements outline what a system must do, focusing on specific actions, behaviors, and interactions. […]

What are Non-functional Requirements: Types, Examples & Approaches

Introduction  Non-functional requirements (NFRs) are essential to software development, shaping how a system performs beyond its basic functions. While functional requirements specify what a system should do, NFRs define how well it should perform. These requirements cover critical aspects such as performance, security, usability, and scalability, impacting a system’s reliability, user experience, and long-term success. […]

Requirement Baselines: Defining, Implementing, and Performing

Introduction In complex project environments, managing requirements effectively is essential to ensure alignment, control scope, and achieve successful outcomes. A fundamental tool for achieving this is the requirement baseline, a clearly defined, approved version of a project’s requirements that acts as a reference point throughout the project lifecycle. Requirement baselines serve as a stable foundation, […]

How to Write an SRS Document (Software Requirements Specification Document)

A Software Requirements Specification (SRS) document serves as the foundation for any successful software project, detailing the essential requirements, functionalities, and constraints needed to meet stakeholders’ expectations. In software development, clear, well-defined, and thoroughly documented requirements are critical for avoiding costly missteps and ensuring alignment across teams. An SRS acts as a comprehensive blueprint, outlining […]
