Review of Lean Topics Dewey Warden I-1 Lean Basics Value stream mapping The seven wastes 5S’s Processes and operations Process flow and cell design Process standardization Overview of quick changeovers I-2 Value Stream Mapping It is the simple process of directly observing the flows of information and materials as they occur, summarizing them visually, and then envisioning a future state with a much better performance. I-3 Value Stream Mapping Levels of mapping Process Single plant Multiple plant Across companies I-4 Value Stream Mapping Creating the value stream maps Walk along the value stream Look for – – – – – Which steps create value? Which steps are waste? Why is order flow so erratic? Why is quality so erratic? How can value be enhanced for the end-customer? I-5 Value Stream Mapping Creating the value stream maps Identify all the physical actions required Identify information actions currently required to manage the value stream I-6 The Seven Wastes Overproduction Excessive inventory Unnecessary conveyance Over processing Excessive motion Waiting Corrections I-7 The Five Ss Set in Order Sort Sustain Standardize Shine I-8 Processes and Operations Processes – A continuous flow in which raw materials are converted to finished products Operations – Any action performed by workers or machines on materials, WIP, or finished products I-9 Processes and Operations Quality process – Focuses on meeting requirements and on minimizing warranty costs Cost process – Seeks to remove excess cost or waste in an organization Delivery process – Manages the elements of time and quantity in sourcing materials, producing and getting product and service to the customer as required Innovation – Maximizes an organization’s success rate I-10 Processes and Operations In a lean enterprise – Value stream maps help to focus an organization on their processes to promote optimization of the whole company’s performance by aligning interests across the company – Process-focused strategies unleash new levels of productivity I-11 Process Flow and Cell Design Wastes in an operation based layout Source: Productivity Press I-12 Process Flow and Cell Design Benefits of a process flow layout – Positioning equipment in the process sequence for a smooth flow – Minimal inventory and delays Source: Productivity Press I-13 Process Standardization Establishes predictability Three elements – Standard cycle time – Standard work sequence – Standard in-process inventory Source: Productivity Press I-14 Quick Changeovers Separate internal setup from external setup Convert internal setup to external setup Streamline all aspects of setup Source: Productivity Press I-15
