Their process is implemented for flexibility first, then for mass production. Look at Toyota fabric [1]. Do you see lot of advanced robots to reprogram for each new model?
So how is/was Fujitsu's laptop manufacturing tailored toward flexibility? I want the details. If all you can do is passive aggressively repeat vague ideas that were printed in mainstream management and manufacturing texts decades ago, don't respond at all. Nobody cares about or wants your input.
And you think that someone from Fujitsu (where it's 8 in the evening, BTW) is going to jump in here and explain their factory layout to you, because you've put your foot down? The best general answer you are going to get is "They made it using whatever process they used to make prototypes. Probably". You want names, ranks, and serial numbers - try writing to Fujitsu. Preferably while being more polite.
