<div class="sreweekly-description">
<p>This episode of Greater Than Code features John Allspaw, and it&#8217;s pretty much as awesome as I expected. Some highlights:</p>
<ul>
<li>rather than asking how an incident happened, ask what prevented it from being worse</li>
<li>ask &#8220;how&#8221; rather than &#8220;why&#8221; an incident happened</li>
<li>humans plus technology are together a cognitive system</li>
<li>how can you make automation a team player?</li>
