As mentioned in my earlier blog post, we hung our visual work instructions above the work station for each operator resulting in no improvement to our process. The only positive impact was with our customers and some of our management on plant tours thinking they looked great. (another example of looking lean versus being lean).
Save yourself some time and effort, any standard work documentation does not need to be posted above the work station for lean manufacturing. Instead, keep a copy of your documentation accessible at the work station (at ground level). It could be placed in a binder, on a ring, or whatever works in your particular operation. The important thing is to keeping it handy not displayed.
Thanks to Mark Graban at the Lean Manufacturing Blog for stating this point in his comments to my earlier posting.
