    • Four Basic Lean Principles
    • Elimination of Waste: Eliminate any activities that do not add value in an organization. Includes overproduction, waiting time, processing, inventory, and motion.
    • Increased Speed and Response: Better process designs allow efficient responses to customers’ needs and the competitive environment.
    • Improved Quality: Poor quality creates waste, so improving quality is essential to the lean environment.
    • Reduced Cost: Simplifying processes and improving efficiency translates to reduced costs.

    • PUSH vs PULL A push system produces finished goods inventory in advance of customer demand using a forecast of sales.
    • Parts and subassemblies are “pushed” through the operating system based on a predefined schedule that is independent of actual customer demand.
    • In a pull system , employees at a given operation (work station) go to the source of the required parts, such as machining or subassembly, and withdraw the units as they need them .
    • By pulling parts from each preceding workstation, the entire manufacturing process is synchronized to the final-assembly schedule.
    • Finished goods are made to coincide with the actual rate of customer demand, resulting in minimal inventories and maximum responsiveness.
