A word on quality
Quality is at the core of everything we do within Lean. When looking at waste within a process the internal cost of quality touches many of the classic 7+1 wastes. W. Edwards Deming aslo point out the hidden cost that we can never truly calculate.
“No one knows the cost of a defective product – don’t tell me you do. You know the cost of replacing it, but not the cost of a dissatisfied customer.”
W. Edwards Deming
“Quality is everyone’s responsibility.”
W. Edwards Deming
