Close vote
Kurt Shuler, vice president of marketing at Arteris, said that it was a “close vote” at the ISO 26262 meeting when the group decided to develop SOTIF as a separate standard. Skeptics questioned the need, he noted. Citing “known unknowns” and “unknown unknowns,” Shuler acknowledged, “We are getting into the realm of Donald Rumsfeld,” the former United States Secretary of Defense.

Calling SOTIF a framework, Shuler explained that SOTIF provides “a way to think about safety” and to “suss out” how certain things could hurt autonomous driving.

In his view, SOTIF is a starting point. “Is SOTIF useful? Yes. Is SOTIF necessary? Yes. But is it sufficient? No.”

Pending issues of SOTIF
As Shuler noted, an industry group like ISO 26262 and SOTIF includes delegates from various geographies and engineers from companies with diverse automotive experience. Some have done pioneering work on ECUs for automotive. Some are disrupters like Tesla and Waymo barging afresh into automotive. Sitting in the middle are traditional car OEMs and Tier Ones from countries accustomed to a slower, highly regulated environment, he explained.
