Toyota is generally reckoned to be a master of mass production, not only in the automotive arena but by the wider world too.
Kanban-style just-in time parts deliveries, kaizen policies of continuous improvement – Toyota has been a banner-carrier for these and many other methodologies that long ago gave it an edge when it comes to productivity and robust, repeatable quality.
So it’s a bit of a surprise to hear, as we did last week in Toyota’s Nagoya headquarters, that the company has been a bit less effective when it comes to parts standardisation, platform sharing and common parts strategies.
The company’s R and D chief Mitsuhisa Kato implied as much when he revealed more details of the strategy behind the Toyota New Global Architecture initiative, the first fruits of which will appear in 2015 with a new Prius.
New models of much the same size and mechanical make-up will be developed in component and structure-sharing clusters rather than individually, and across regions too. Sharing the hip-points of cars’ driving positions will yield major savings in airbag, seat-belt, pedal box and steering column design. And the result of these standardisations, and more, will allow parts procurement on a wider and less costly basis.
