I dont doubt the effectiveness or the decision to build a secondary assembly line in a pop-up semi-permenant structure. I feel the mistake was calling it a ‘tent’. It just builds the wrong picture in peoples minds.
A full assembly line makes me think of robots, automation and precision.
A tent makes me think of men with paint brushes, screwdrivers and a hammer to make it fit.
Call it a ‘secondary assemby line’ if pushed on the method. Say its a semi-permanent sprung structure, and push the point its no different to a full production line with emphasis on quality contol.
