Requirement and Test Traceability

Requirement and Test Traceability – Any added value?

Veröffentlicht Veröffentlicht in Englische Blogs, Requirements Engineering eng, Uncategorized

Requirement and Test Traceability: 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 […]

Requirement Engineering for Embedded and IT systems – It’s time for the embedded community to become aware of the differences!

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Requirements Engineering eng

If you analyses the book market, publications or conferences on requirements management and Requirement Engineering, 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 Schreibe einen KommentarVeröffentlicht in Englische Blogs, Requirements Engineering eng

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 den meisten Publikationen zum Thema Requirements liegt der Schwerpunkt auf den Management Aspekten. Viel diskutiert sind die Thema Erfassen und Verwalten von Requirements. Im nachfolgenden Blog arbeite ich heraus, welche wichtigen Aspekte immer wieder zu kurz kommen. Meine Betrachtungen starten mit der Definition von Requirement Engineering im Buch „Basiswissen – Requirement Engineering“ (Klaus Pohl, […]

Compiler for safety critical software – What needs to be done?

Veröffentlicht 1 KommentarVeröffentlicht in Englische Blogs, Functional Safety

The compiler is the central „tool“, which is required for every software development. It forms the link between the human-readable high-level source code (e.g., C and C ++) and the machine code, interpretable for the hardware processor. For the development of safety critical software according to relevant functional safety standards special requirements apply for the tools […]

Implicit Testing – A good idea (Part 1)?

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Englische Blogs, Validation and Verification

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 […]
