Writing Good Requirements

Course Category: Fundamentals
Course Duration: 1 day
Course Credit: 7 PDU
Prerequisites: None

Writing requirements and delivering a well written requirements specification that is clear, correct, concise and complete is hard work. This work is often made harder because most people do not know how to write requirements. The fact that the most common reasons for project and product failures are problems with requirements supports this assessment.

In this one-day writing good requirements training course, you will learn what you need to do before you write requirements, best practices for writing good functional and non-functional requirements, and the techniques that can be applied and the attributes captured to improve the overall quality and understanding of your requirements.

You will learn to:

Write requirements to best practices and apply various techniques to avoid writing bad requirements
Quickly identify and fix bad requirements
Use rationale to clarify each requirement so that it is understood just one way and you have a history of why the requirement exists for purposes of change impact assessments, maintenance and verification
Use attributes such as verification method, allocation, and traceability to improve your requirement set
Write different types of functional and non-functional requirements
Validate your requirements as they are written to avoid preparing and submitting a bad requirement specification for review
