<p class="x_MsoNormal">Hello All </p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Recently Earl brought to my attention another traveler where there are mixed work centers in the same traveler – while I realize PPU may be getting close to the end, it would never the less be nice if we could get this problem fixed,
and come up with a systematic approach so that work centers are no longer being mixed . I agree completely with him that this is a problem when the work of other work centers is mixed into inspection work – we have no way to track parts once they leave our
work center . He is correct this problem seems to be re-occurring - we find mixed work centers on Inspection travelers quite often for other projects as well , so this problem is not limited to PPU
</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I am including Ashley in this discussion since she is the Project Co-coordinator for PPU . Do you think it is possible to put the leak/pressure test into a different traveler ? I don’t mind to go through all the other projects & travelers
and look for where we have mixed work centers occurring in Inspection , of course this will then mean a new traveler will be needed for leak test
