SysML: From idea to simulation in 30 minutes
A SysML model is much more than a diagram. This example with Cameo shows model simulation, with video.
Systems Engineering at SpaceX
Systems engineering at SpaceX works differently than anywhere else. What we can learn from this in systems engineering.
6 lessons for Systems Engineers from the Boeing 737 MAX disaster
The Boeing 737 MAX accidents were a tragedy with hundreds of fatalities and a disaster for Boeing, with MCAS software at the center of it all
The new trinity of artificial intelligence
Artificial intelligence (AI), machine learning, big data - all nice words. But what do they mean, how can they be used and what does this mean for systems engineers? Three things are needed to use AI effectively: Software, powerful computers and data. How exactly this works, and what role humans play as a system element, is what...
User-friendliness vs. security - really a compromise?
In system development, the struggle is an old, perennial problem. User-friendliness is often the top priority for new commercial projects. But without the appropriate security, nothing works - public attention is increasingly focused on data security. At the same time, as part of the Internet of Things (IoT) revolution, the market is expecting a flood of affordable, simple and...
What to do to prevent security from becoming a PR disaster
How would you react if someone told you that your product could be hacked to such an extent that it could lead to fatalities? This question is not out of the question: Pacemaker manufacturer Medtronic was warned and failed to act for 18 months. Is this irresponsible behavior, or is the security researcher-described...
The connected car: C-V2X in Denver
Connecting cars has many promises, such as saving time (navigating around traffic jams, guiding you to the parking lot), money (driving in a platoon) and safety (warning you of dangers). But of course there are also risks, especially in terms of safety. These can be caused by bugs, incompatibilities or malicious activity. But this will not stop progress, and the city...
A different take on meta information: 5 alternatives to attributes
Attributes are everywhere: When we record requirements, we typically record a priority, generate an ID, save the author, etc. in addition to the description. All of these are attributes. Specific attributes are then often added, such as a security requirement level. Attributes are also used in further development: For example, many SysML model elements have dozens of predefined attributes. And of course...
How many requirements do we really need?
It is astonishing how many - or how few - requirements are articulated for comparable products. The automotive industry is notorious for the sometimes incredibly high number of requirements (Audi recently quoted the figure of "60 million" in a keynote speech). Of course, this is not entirely fair: after all, requirements have to be formulated on many levels. Nevertheless, for...
Why the band OK Go is involved in systems engineering
In recent months, the band OK Go has managed to produce several videos that have gone viral on the internet. These included a video recorded in parabolic flight, which takes place in apparent weightlessness, or a 4-minute video, which was recorded in 4.2 seconds. What does this have to do with systems engineering? I will answer that in the following...
Century support part 2: How not to start
This guest article by Carsten Pitz is the second part on the topic of long-term support. In the first part, Carsten describes the development of a documentation system. Although it was not initially conceived as such, it became clear over time that the system would have to be available for decades. Enjoy reading the second part.
Century Support: Why long-term care is a real problem
Long-term care is particularly problematic in aviation, where a product has to be maintained for up to 100 years: Century support!
