<blockquote><p>This paper discusses the ways in which automation of industrial processes may expand rather than eliminate problems with the human operator.</p></blockquote>
<p>My favorite bit of irony: presenting data to the user in the manner most readily understood results in lower likelihood of remembering the data, so perhaps the most easily grasped display is not actually the best!</p>

<p>Whether or not you agree with this particular attempt at defining what a Systems Engineer (or SRE or anything related) is, it&#8217;s worth thinking about and discussing. Our field is evolving quickly, and titles are a moving target.</p>

<div class="sreweekly-description">
<p>Driven by a desire to update their 737 without causing airlines to have to retrain pilots, Boeing seemingly kept pilots in the dark about what may have been an important little detail of how the new 737 Max operates, with a tragic result.</p>
