Safety is one of the most important properties of nowadays embedded systems. Along with system complexity, the complexity of safety engineering grew alike. Many engineers in industry face the challenge that they do not oversee what is necessary to develop a safe system anymore. The putative way out of this misery is to buy the relevant (international) standard for functional safety and obstinately follow the requirements written in there. But this appearance is deceiving. Standards for functional safety (and standards in general) have the disadvantages that as more detailed the standards prescribe things, the less people think about what it means to build a safe system. Contributing to this nuisance is the plethora of available seminars, and companies making money out of the needs of the engineers. In the end most of the seminars do not really help the engineer in understanding the standards or more importantly functional safety, but even worse they further push the idea of unattainability of the Holy Grail "safety".
We literally reach out a helping hand to these engineers (and researchers). "Literally" is meant in the sense that we reduced this overvalued, almost artistic discipline, safety engineering, to five main principles: One for each finger! Thus, all you need is a "handful" of safety.
