The document discusses several key concepts in lean manufacturing including:
1. The goal of lean is to identify and eliminate waste in the production system through techniques like 5S, standardized work, visual management, and kanban pull systems.
2. Value-added activities are those that customers are willing to pay for, while non-value added activities are waste that does not contribute to the product.
3. The seven types of waste or "muda" are overproduction, waiting, transportation, overprocessing, inventory, motion, and defects. Methods like kaizen aim to continuously eliminate these forms of waste.

Lean Manufacturing provides a vehicle for waste elimination. The goal of Lean Manufacturing is to totally eliminate all waste from the system. This goal while being unrealistic in practical application sets the stage for continuous improvement. It is necessary to understand that the inherent nature of continuous improvement philosophy is de-motivational for operators, undoubtedly the workforce will realize that no matter how hard they work to improve, there will always be another opportunity for improvement. In order to sustain operator enthusiasm toward waste reduction, it is important to recognize and celebrate small successes as they occur.
Though out the gradual implementation of Lean Manufacturing, it is vital to maintain focus on the elimination of waste. Each of the 5 Steps to lean manufacturing incorporates specific practices that are required to maintain the next level. It is not possible to move ahead with implementation until the practices have been successfully implemented.
