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, […]
In the first part of the blog I defined the term “Implicit Testing” and discussed root causes for the need of implicit tests. In the second part I will focus on the disadvantages of such tests and on possible solution approaches with the goal to avoid these disadvantages.
In larger safety-critical projects, quite often I hear the following statement: “Well, the Requirement A is indirectly or implicitly proven with the test XY!” Do you know this sentence as well? Have you ever experienced what can happen in late project phases when you have tested many requirements indirectly? The blog defines the term in […]
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 The classic approaches, especially the waterfall model and the V-model, seem to be more and more outdated.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 […]
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 […]
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 […]
