<p class="MsoNormal">When it comes to serial numbers: Yes, there is a move to add more and more significance to the “human-readable” serial number. If this is the only way to identify a specific instance of a part number, then this will inevitably lead to inconsistencies
again. Just like what happened with part numbers.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">In my view, there need to be 2 things, when it comes to serial numbers:<u></u><u></u></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">A human readable form.<br>
This one can have as much significance as the user desires. Have it identify product, where it was made, when it was made etc etc.<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">A UUID to track this specific instance.<br>
This number would be used by the applications to identify specifically which part we’re dealing with.<u></u><u></u></li></ol>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">The combination of both will always be unique. The human readable will inevitably lead to duplication, or massive inconsistencies when people are encouraged to re-use design on other assemblies.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am advocating for human-readable/UUID combinations for many identifiers such as:<u></u><u></u></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Part Number<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Serial Number<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Engineering Requirement<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Shop Order Number<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Person operating the equipment<u></u><u></u></li><li class="gmail-m_-919210724754642282MsoListParagraph" style="margin-left:0in">Etc.<u></u><u></u></li></ol>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We are still in a world where we do a lot of the manufacturing orchestration by hand. That drives the need for human readable forms of these identifiers. But long term, as orchestration processes get automated, there is a need for UUID’s.
Since humans are going to be always in (or at the very least close to) the loop, human readable forms are important. But the inconsistencies that that brings, need to be countered by a UUID, which will take a more and more central role as automation get s
introduced.<u></u><u></u></p>
