Course Overview

Non-Functional Requirements (NFR): for BA, QA & Developers

Learn to define, analyze, and document NFRs with real examples for BA, QA, Architects, and Developers

Non Functional Requirements are one of the most important parts of software quality. A system can work, but without clear NFRs it may fail in performance, reliability, security, scalability, or usability.

Many projects struggle because NFRs were missing or unclear. This leads to rework, delays, and problems in production.

This course gives a simple and practical way to understand, define, and document NFRs. You will learn how to gather NFRs during discussions with stakeholders and how to create clear and useful requirement statements.

You will also learn how to identify common types of NFRs related to performance, security, scalability, usability, and availability. The goal is to help you create NFRs that support better design and better project outcomes.

This course is useful for business analysts, QA engineers, developers, architects, and students who want to understand how NFRs shape the quality of a software system.

    As a BA, I found this perspective on Non-Functional requirements useful. The sound on recording was pretty quiet, it would be great is the sound volume was improved.
