7 Planning and Scheduling Lean Operations Copeland Corporation Closing The Gaps – MRP vs Lean Lean Material Systems Must: - Be Highly Flexible (Daily Capability) - Exception Based - “Expected” Demand Covered By Pull Systems/ POU - Require Minimal Transactions To Support - Flat Bills - Backflushing Essential - Support Much Less Inventory/ Safety Stock - Inventory Accuracy IS Critical - Cycle Count Program Essential – Cause and Effect Focused - PC Based, Can Not Wait For Overnight Runs/ Updates
8
8 Planning and Scheduling Lean Operations Copeland Corporation Analysis MRP Function Changes - Long Term Forecast To Supplier - Transaction Processor/Collector - Data Warehouse – Download Of Static Data To PC - Develop Daily “Kanban” Capability MRP Is Separated From Shop Floor/Purchasing Activity - Responsiveness No Longer Limited To MRP Run Frequency

12 Planning and Scheduling Lean Operations Copeland Corporation Flow Results On Time Delivery (Pre-Flow) –1997 94% On Time Delivery to Customers –199886% –199983% Since Flow Implementation –200090% –200195% (98% 2 nd Half of Year) Lead Time Reduction – Up To 66% (So Far) Inventory - First Higher (Stabilization) - Now Dropping Productivity – Pockets of Improvement Expanding Rapidly
13
13 Planning and Scheduling Lean Operations Copeland Corporation Issues Lumpy Actual Demand - Often Caused By Process, Shortages, Pulls/Pushes - When Actual Demand Exceeds Pull Sizing - Utilize MRP To Recover Changing Old Habits/Mindset Issues – Across Supply Chain Maintaining Labor Efficiencies Operating With Less Backlog (Safety Blanket) Right Sizing Inventory – Short Term Increase Old Metrics No Longer Valid – New Metrics Needed
14
14 Planning and Scheduling Lean Operations Copeland Corporation Supply Chain Management Some Suppliers Unable To Reduce Lead-Time - Offshore Sourcing - Consignment, VMI, Right Sizing Work With Strategic Suppliers - Set Up Reduction, Pull Systems - EDI, B2B Ordering - Cycle Time Reduction - More Responsive/Competitive Change Expectations, Incorporate into Contracts
15
15 Planning and Scheduling Lean Operations Copeland Corporation Next Steps Full e-Business Implementation Database Warehouse B2B Data Transfer Supply Chain Development - Supplier – MCT/Lead-time Reduction - Customer – Point of Sale Replenishment - Daily Ordering - Freight Management
16
16 Planning and Scheduling Lean Operations Copeland Corporation Summary Companies Are Implementing Lean Concepts To: Increase Responsiveness Improve Productivity MRP Systems Must Adjust To New Requirements From Lean Operations Less Complexity More Frequent Updates, Exception Based Support Flatter BOM’s, Fewer Transactions Better Metrics And Data Collection/Download Capabilities e-Business Support Even With Less Complexity, Some ERP Modules May Be Eliminated Visual Systems, Hands On Management
