person Author: Alexander Feulner
The increasing complexity, shortened development times, distributed development, heightened cost pressures, technological change, and organizational transformations are just a few of the challenges facing the current development. If these statements seem unfamiliar to you, we congratulate you warmly. For all those who are confronted with these challenges on a daily basis, we present the methodology of ‘Systems Engineering’ in our webinar and answer the question: "Why the heck do we need this?". This webinar is tailored not only for system developers but also for professionals in various domains including software development, hardware development, testing, project management and more.

person Author: Process Fellows
Test Management ensures that testing activities are strategically planned, monitored, and evaluated across all development phases. From unit tests to system-level integration, this cross-cutting discipline defines methods, tools, documents, and roles to ensure traceable and efficient verification and validation.

arrow_forward "Verification level vs. Verification timepoint"

person Author: Process Fellows
The execution of a verification measure is not necessarily linked to the verification time point. It is possible that a verification measure from SWE.6 is carried out as part of the verification of the SW component and integration verrifcation if the setup or the environment is better suited to this. However, it remains a verification of the SW requirements. The decisive factor is what a verification measure is derived from. However, it is important to ensure that this verification measure is included in and part of the report and in the summary of the SW verification. Pay attention to the sequences and dependencies to be followed.

Don’t lose your evidence. With perspective to testing, SUP.8.BP1 in combination with SUP.8.BP8 expects structured storage of test logs, verdicts, anomalies, and configuration info. This is not only a formality: It enables you to later on reproduce details about a certain system version.

BP4 Ensure consistency and establish bidirectional traceability. ( O4, O5 )

Ensure consistency and establish bidirectional traceability between verification measures (Verification measure = Verification measure can be:

• Test cases

• Analyses

Note 4: Bidirectional traceability supports consistency, and facilitates impact analysis of change requests, and demonstration of verification (Verification = Verification is confirmation through the provision of objective evidence that an element fulfils the specified requirements.) coverage. Traceability alone, e.g., the existence of links, does not necessarily mean that the information is consistent with each other.

arrow_forward "Consistency vs. Traceability – What’s the Difference?"

person Author: Process Fellows
Consistency ensures that related content doesn’t contradict itself – e.g., requirements align with architecture and test. Traceability, in contrast, is about links: can you follow a requirement through to implementation and verification? Both are needed – consistency builds trust, traceability enables control. Typically, traceability strongly supports consistency review.

arrow_forward "The role of traceability in risk control"

person Author: Process Fellows
Traceability isn’t just about completeness — it’s about managing impact. When a requirement changes, trace links tell you what’s affected. That’s your early-warning system.

arrow_forward "The true benefit of traceability "

person Author: Process Fellows
Sometimes the creation of traceability is seen as an additional expense, the benefits are not recognized. Traceability should be set up at the same time as the derived elements are created. Both work products are open in front of us and the creation of the trace often only takes a few moments. In the aftermath, the effort increases noticeably and the risk of gaps is high. If the traceability is complete and consistent, the discovery of dependencies is unbeatably fast and reliable compared to searching for dependencies at a later stage, when there may also be time pressure. It also enables proof of complete coverage of the derived elements and allows the complete consistency check.
