<p>NASA chose to squeeze just a bit more science out of the Voyager spacecrafts&#8217; aging power supplies by sacrificing a layer of redundancy. I love this so much, because it sounds just like the kinds of decisions we make during incidents.</p>

<p>I really debated about including this one, because I don&#8217;t often include articles about new products, and Ii think especially critically when the the company in question is my employer.</p>
<p>With all that in mind, I&#8217;m including this one anyway because Charity Majors really put a fine point on exactly why I, too, am cranky about AIOps.</p>

<p>The main reason that MTTR is a flawed metric is that the nature of each incident varies so wildly. Time to assemble, though, is much closer to being under our control.</p>
