I don’t see how a one-day factory stoppage aligns with the article’s teaser, “ Just in time’ production system minimises costs but technical glitch highlights risks.” It seems like Toyota identified the issue and got things running again quickly enough. This does not at all seem like a good case study for exploring the risks of JIT. I read The Guardian regularly and will continue to, but they sometimes go out of their way to find an anti-business angle.
