The five core principles of lean are fully covered by the LBMCs four lens approach,
which can easily be applied to any business no matter what the size.
All the lenses are associated with every principle, but in varying degrees. With
the key focus being improvements that have an impact on the end customer. A business
usually can not charge extra for good customer service so applying the four lenses
to improve your products and services cost, quality and delivery will drive your
business forward
