As a woman in a project management role, I use my advantages to the fullest. If I have a "stupid" question, the guys on the shop floor are a lot more patient with me asking it than they would be if I were a male asking the same question. I'd be an idiot to not use all of the advantages there...

If I have a CRN for an expansion tank that is 30" OD x 72" S/S can I use that CRN for a new expansion tank that is identical in all other ways except that...
I am relieved to read points d and e, it was my original understanding that if our shop purchased plate/ fittings etc in US units (which is what is readily avaiable), then we could not manufacture/design in SI units (which is what our customer's require). Is it your opinion, Isthill that this...
