Lean is a strategy for achieving significant improvement in performance through the continuous elimination of all wasted resources. It can be used by both manufacturing and service organizations. A Lean process must be fast and flexible in order to deliver products and services to the exact needs of the customer.
Lean has many techniques that can be applied to operations and projects. These techniques allow to map out the value stream, identify and eliminate waste, produce value to the customer and drive organizational change. These techniques can be used in isolation or together. The benefits will significantly increase as more techniques are used since they support and reinforce each other.
