A recent blog post by our esteemed colleague Christer Fröling has sparked a tidal wave of interest and his paper “NLP beats DXL (DOORS scripting) every day of the week” has been distributed widely. But can his claim be substantiated?

In the world of Model-Based Systems Engineering, we usually find a huge ecosystem full of tools. The community of practitioners will be using a wide variety of different tools for Requirements Management, Logical and Physical Modelling, Traceability, Simulation, Quality Management etc.

This Webinar describes a real scenario where, while working in a model-based project using Rhapsody, there is the need of writing high quality requirements concerning the UML/SysML elements of the project.

Nowadays, very few companies develop, distribute, and sell products end-to-end. On the contrary, it’s quite common to find the supply chain approach, where many suppliers might be involved in the whole product lifecycle. This may lead to specialization, cost reduction, and scalability.

Model-Based (MBSE) is the current trend in regard to Systems Engineering, leveraging testing and simulation activities. However, it’s also clear that textual requirements will remain in the scene since they are also key for testing, certification, and communication with other stakeholders.

Completeness is, by far, the most difficult quality characteristic to be checked in our requirements specifications.

Once the correctness topic is properly addressed, the real problem when analyzing the overall quality of a project (in terms of its requirements) comes with the consistency among the different requirements, that many times are written by different people, in different places… Not to mention the consistency between requirements and models in a MBSE environment.

When you are bidding in a public tender, every minute counts. Even for the more experienced analyst, the short time that is available makes it very difficult and risky to come up the right bid, the one that presents the best budget by maximizing existing asset reuse.
