Commenting on Boeing's safety standards, SMU Assistant Professor of Strategy & Entrepreneurship (Education) Terence Fan said that the crisis over Boeing’s narrow body aircraft comes only a few years after the one it faced in 2019. He explained how this sequence of events could be symptomatic of “a deeper malaise”. Asst Prof Fan said that while Boeing had traditionally featured engineers in its leadership, this approach had changed recently. He added that supply chain issues have also plagued Boeing ever since the start of the pandemic in 2020.
