Requirement Engineering

If you analyses the book market, publications or conferences on requirements management and engineering (RE), you will find that more than 90% consider requirements engineering from the point of view of IT software systems. There are very few publications that look at the topic from the perspective of embedded systems. On the one hand, it […]

RE Engineering – Aspects which even not considerd in RE theory!

Veröffentlicht am

In most of the requirement engineering publications, the focus is on management aspects. The collection and management of requirements is discussed extensively. In the following blog I discuss important aspects which are not sufficiently considered in the RE theory. I start with the definition of Requirement Engineering in the book “Requirements Engineering Fundamentals” (Klaus Pohl, […]

User Stories – The better Requirements?

Veröffentlicht am

The book “User Stories” from Mike Cohn (ISBN 978-0321205681) has inspired me to think about the relationship between user stories and requirements. In software development, agile methods are often preferred in recent years. The classic approaches, especially the waterfall model and the V-model, seem to be more and more outdated. As a result, user stories […]

Structural source code coverage and Requirements – Is there any dependency?

Veröffentlicht am

If you are newly engaged in the area of functional safety, then you will encounter fairly quickly the terms “structural source code coverage” and “requirements”. The specification of technical systems by requirements is, of course, also common in non-safety-critical areas. By contrast, the subject structural source code coverage is almost unknown outside safety-critical projects. In […]

Non-Functional Requirements – A challenge?

Veröffentlicht am

According to my observation requirements engineering in general doesn’t get the appropriate attention. If you consider software and/or hardware projects which failed, you can see that often a missing or incorrect requirements engineering is one of the major causes. If we go further and consider the types of possible requirements, then you can make a […]

Traceability – Any added value?

Veröffentlicht am

Think about the following situation: You are near the end of your safety-related project and you have established traceability between all the project artifacts. In an audit (e.g. Internal Quality Assurance, Customer, External Authority) you have to demonstrate which software requirements are developed from which System Requirements. Each software requirement is linked to one or […]
