Removed unsourced material
I just removed this sentence: As noted by John Bicheno, Toyota's adoption of the Hirano approach was '4S', with Seiton and Seiso combined
as it is not supported by any RS. I even checked the Bicheno's New Lean Toolbox as referred to in the article, there is no so-called information of "Toyota's adoption of the Hirano approach" and "4S". Please feel free to revert my edit if you find the RS for this material. Ltncanada (talk) 21:07, 11 November 2021 (UTC)
