Traceability can never start too early: Pre-Requirements Specification Traceability
Traceability in requirements management and systems engineering is now a well-understood topic. But do we have traceability for what happens "before"? This refers to traceability to interviews, meeting minutes or legacy systems. This traceability becomes more important as complexity increases. In this respect, I found the recently published meta-study by Julia Mucha, Andreas Kaufmann and Dirk...
Traceability: The most important link types
Traceability is important and links have semantics. The most important link types are presented below.
Review: INCOSE guide for writing requirements
The INCOSE guide for writing requirements helps with the description of complex systems.
Why do we ignore the quality of traceability?
Traceability is undoubtedly an important concept in systems engineering. In many cases, traceability is even prescribed, especially in the context of functional safety. However, the quality of traceability is rarely questioned (except perhaps in an audit) and even more rarely is it actively used in development. This is a problem, because without quality...
The digital thread: SE arguments for decision-makers
The digital thread goes far beyond traceability, enabling end-to-end tracking for all stakeholders.
The triangle of complexity, quality and productivity
Systems engineering consists of many trade-offs. The triangle shows how we can optimize the interdependencies between complexity, quality and productivity.
What is an ontology? And do I need one?
An ontology is the structure of terms, their meaning and relationships. It ensures precision in product development.
Why doesn't anyone stick to text templates for requirements?
Text templates for requirements have been around for a long time. The concept is simple: a handful of text templates can be used to express all conceivable requirements. Using the templates results in well-formulated, high-quality requirements. However, in an industrial environment, their use is the exception rather than the rule. The reason is not difficult to...
3 approaches to processing natural language requirements automatically
Model-based system descriptions are useful, but almost all developments start with requirements in human language. This will not change any time soon, because systems are developed for people. After all, we think in natural language (and images). However, natural language cannot be processed automatically without further ado, but especially with increasing complexity this would be...
Traceability: an alternative to expensive tools?
Expensive traceability tools are justified for safety-critical systems, otherwise the cheap alternative is sufficient.
