We can look at DevOps as an extension of Lean manufacturing, with extras added like the Toyota Kata, and modifications made in order to make with work better and make sense to software development.
It is a great case study of how to successfully apply Lean to a different industry, and a great many things can be taken from it in order to apply to other industries.
For example, I know of a botched implementation of applying Lean to healthcare, and I believe if a DevOps style route was taken, it would be more successful. DevOps isn't applying straight Lean itself but making modifications where it makes sense, and I think a lot of the modifications made by DevOps would make sense to other industries.
There is "Lean IT", but I would be wary of applying it without doing some studying on DevOps first, since I view DevOps as the gold standard of how to apply Lean to your industry (aside from the whole buzzword confusion)
