The foundation of Lean is based upon in simple goal of identification and elimination of waste in all work activities. Observation of activities in the process, material, and information flows, can result in identification of huge amount of Non Value adding activities, usually far more than value-added activity. But seeing the waste is not the same as eliminating it. The challenge is to develop a systematic method for continuously identifying and eliminating waste. A sporadic removal will yield pockets of improvement, but the system-wide benefits can be achieved by following a cyclical method of continuous improvement.
