Requirements Engineering: A Practical Introduction
A plain introduction to requirements: what they are, why they matter, and how needs turn into requirements, design and tests across a project.
Engineering Fundamentals
Requirements and Specifications
Capturing what a system must do and proving that it does.
Acceptance Criteria and Definition of Done
How to agree in advance how work will be judged complete: writing clear acceptance criteria, using a team definition of done, and avoiding disputes.
Functional and Non-Functional Requirements
Understand the difference between what a system does and how well it must do it, with everyday examples and tips for writing both kinds clearly.
Gathering Requirements from Stakeholders
Practical techniques for learning what users and clients need, including stakeholder interviews, observation, workshops and ways to check what you heard.
How to Write Good Requirements
The qualities of a well-written requirement, such as clear, testable and unambiguous, with before-and-after examples you can adapt to your own work.
Managing Requirement Changes
Why requirements change, how to handle change requests sensibly, and practical ways to keep scope under control without blocking useful improvements.
Reading and Writing a Technical Specification
How a technical specification is organised, what each section is for, and how to read one critically or write one that others can build and test from.
Traceability: Linking Requirements to Tests
How requirements traceability connects each requirement to design elements and tests so that gaps, orphaned work and change impact become visible.
