Just like the immense sins of Jack Welch and GE will always tarnish six Sigma it is past time to realize that the conservative, looking backwards to Toyota of much of Lean thinking is a mistake that limits adoption and more importantly innovation.
As a company there is much at Toyota that is just wrong. The 2020 recalls were significant, but frankly not the first year the company has been having major quality contorl issues.
But more important is the fact the company is a liar and a supporter of authoritarianism. As a promponent of the pillars of Lean thats just damn hypocritical. After the failed coup of Janaury 6th, Toyota pledged to no longer fund anyone who supported the attack against US democracy. As of June they are the top fundraiser to those Republicans, giving to nearly a quarter of the 147 GOP politicians who objected to certifying the election results.
Toyota is showing us who they are. A company that stands apart from the principles so important to the Quality profession.
