We recently worked with Fluere on our Lean Manufacturing implementation. Having been through this iteration a few times, the hands-on, no BS, adaptation to our culture was a refreshing change.
As expected in this type of project, we had our ups and downs, our missed targets and wrongly defined requirements, but we always got their in the end. Whilst we must have been a source of frustration at times, never once did they show this externally, always with a smile, and always with empathy. If you are about to engage in a Lean Project, add Fluere to your list.
