Why is the reuse of software, hardware, or complete electronic control units a central theme? Two essential aspects are to be considered: the development costs can be reduced significantly, i.e. reuse of components is very attractive in economic terms. But also for security reasons, the reuse of components can offer significant benefits. A control unit, […]

According to my observation requirements engineering in general doesn’t get the appropriate attention. If you consider software and/or hardware projects which failed, you can see that often a missing or incorrect requirements engineering is one of the major causes. If we go further and consider the types of possible requirements, then you can make a […]
