Why Current Safety Analysis Methods Fail at Covering Lethal System Designs (.PDF Download)

When we look at today's focus of our safety efforts, we see that we mostly deal with the following topics:

• Functional safety
• Safety of the intended functionality (SOTIF)
• Safety in use (SiU)
• Security
• Active/passive safety systems

Functional safety and the ISO 26262 deal with safety-related systems that include one or more E/E systems (electrical and/or electronic) and the corresponding hazards that come from a malfunction of these E/E safety-related systems. Safety of the intended functionality (SOTIF) refers to hazards resulting from functional insufficiencies of the intended functionality.
