<p>The <a href="https://stats.stackexchange.com/questions/tagged/reliability" class="post-tag" title="show questions tagged &#39;reliability&#39;" rel="tag">reliability</a> tag is meant for reliability of measurements, but today <a href="https://stats.stackexchange.com/questions/414520/calculating-failure-rate-with-some-failure-cause-data-being-vague">https://stats.stackexchange.com/questions/414520/calculating-failure-rate-with-some-failure-cause-data-being-vague</a>  (and certainly before) somebody used it in the meaning of "reliability theory", as used in engineering and other fields, and covered by books like <a href="https://rads.stackoverflow.com/amzn/click/com/047147133X" rel="nofollow noreferrer" rel="nofollow noreferrer"><em>System Reliability Theory Statistical Applications</em></a>.</p>

<p>What should be done here, put a different tag, or are there existing tags for posts like the one linked? </p>

<pre><code> EDIT

<p>After a day, it seems the question was interpreted very narrowly. I meant not just that specific post, but <strong>the tag name invites misinterpretation</strong>. We could change the name, maybe measurement-reliability or something similar, and then maybe later, for the technological use, systems-reliability ?</p>

<pre><code>EDIT  Again

<p>The issues is not resolve, today a post <a href="https://stats.stackexchange.com/questions/444508/reliability-of-a-multistate-item">Reliability of a multistate item</a>  which uses <a href="https://stats.stackexchange.com/questions/tagged/reliability" class="post-tag" title="show questions tagged &#39;reliability&#39;" rel="tag">reliability</a> for what is really engineering reliability ( or systems reliability), another concept. Should I just go ahead and introduce a new tag? What should be the name? engineering-reliability or systems-reliabiliy, or better suggestions? Here <a href="https://www.amazon.in/Stochastic-Reliability-Modelling-Applied-Probability/dp/1489998551/ref=sr_1_7?keywords=reliability+models&amp;qid=1578923611&amp;s=books&amp;sr=1-7" rel="nofollow noreferrer">https://www.amazon.in/Stochastic-Reliability-Modelling-Applied-Probability/dp/1489998551/ref=sr_1_7?keywords=reliability+models&amp;qid=1578923611&amp;s=books&amp;sr=1-7</a> is a book defining the tag, more or less.</p>
