The GAIA production lines consisted of production equipment that were geared towards mass production.
This meant that they aimed for the highest possible quality within a few important constraints.
First, they had to be fast enough. If it took twice as much time to produce a mech, then the mech company in question was practically losing a lot of money due to having less mechs for sale.
Second, they had to be easy enough for mech technicians to operate them. The production machines had to take the limited capabilities of average factory workers into account.
Of course, different production machines imposed different minimum skill requirements. The GAIA production line was quite advanced, so the mech technicians had to be a lot more skilled and knowledgeable than normal in order to produce high-quality mechs like the Transcendent Punishers.
