I believe this system is indeed revolutionary. Mostly because I see this whole system to be really efficient. Just in time, mostly cuts out waste of material and parts, saves time and most importantly saves cost. Having consistency makes sure cars or models of cars are mass produced, and as quickly as possible. I think standardized parts and models made the cars easy to maintain afterward too. Most importantly, quality check at every point of manufacturing and through quality check of the finished car makes sure that the customer is getting the best possible quality.
TNGA was required to meet changing customer needs. Every year each manufacturer are bringing out better-looking cars with enhanced features and exteriors. So, while Toyota was making sure of standard and quality but the process made it difficult to change the design or introduce change. Now TNGA as a platform allows Toyota to minimize parts while maximizing variations per customer needs, so of course, this is revolutionary.
For a customer, quality means performance, features, reliability, conformance, durability, serviceability, aesthetics and other perceptions. The customer defines quality, so customer requirements should be met if feasible (James, 2011). I believe this new approach will produce better cars with more features, reliability and better aesthetics, hence customers will like the new cars better. I believe this will be the new change in the quality strategy.
Toyota will be building new era cars with the minimum number of different components (Toyota, 2015), which means better serviceability, better performance, and cars with better aesthetics. But most importantly I think Toyota will be able to introduce a change in less time in their cars. So from plant to market, the required time will go down and Toyota will be able to change or enhance their existing models faster.
