Using ERP in aLean Manufacturing environment Andy Barnes Operations Manager Snell & Wilcox Ltd
Outline Agenda • About S&W • Supply Process Improvement • MFG Pro in a Lean Environment
History • 1973: founded by Roderick Snell and Joe Wilcox • To focus on the preservation and improvement of the television image • 1988: Joe Wilcox retires, 24 employees • 1993: Introduction of Alchemist with ‘Ph.C’ • 1994: Acquired CEL Ltd • 1996: MPEG (Moving Picture Experts Group) activities began • 1999: MXF (Material Exchange Format) work starts • 2001: Acquired Post Impressions and PSP • 2005: Turnover ~£36m, 350 employees worldwide
Award winning record • Four technical Emmys • Phase correlation motion compensation (Ph.C) - the key to superior standards conversion • Prefix MPEG pre-processing - saves storage and transmission costs • DEFT 3:2 cadence detection and repair - improves Hollywood workflow efficiency • HD up and down conversion - for flexibility in production and broadcast • Many other awards: • Eight Queens Awards • First to win two IABM Peter Wayne Technology and Innovation Awards
Locations HQ, R&D, Manufacturing Southleigh Park, Havant R&D, Manufacturing Saffron Walden R&D Newbury, Liss, Montreal Sales and Service UK, France, Germany, Russia, USA, Hong Kong, China, Japan, India, Lebanon Southleigh Park
Historical Process • Forecast driven batch build process (push) • Long lead times ~4-6wks • Poor levels of customer service - OTD ~55% • High levels of inventory - stock turns ~4/annum • Quality issues highlighted late in build process - Rework
Objective Improve historical levels of on time delivery, lead time and quality to world class levels: S&W Target On time 55% >98% Response 4-6 wks <5 days Quality ??? ppm
Time for Change- Spring 2004 • Established a full time multi-functional team • Capability through intensive training • External support - Cranfield Consultants • Pilot project using simple product family - Kudos+
Motion • Transportation • Waiting time • Overproduction • Inventory • Processing time • Defects • Energy • Untapped human resources • By-products • Inappropriate IT support Types of Waste The Seven Wastes Other Common Wastes
Batches Space Transport / handling problems (damage) Time to make batch - some of which aren’t needed
The Problem with Batches • Pushing Batches Through • Cycle time to make whole batch – not just what customer ordered • Waiting for other batches • “Pinching” from one batch to fulfil “more urgent” order • High inventory everywhere • Response time = time for complete batch to move through complete process, queuing behind other batches Inventory SMT Robotas Flow Solder Electrical Assembly Mechanical Assembly Test Soak Distance travelled between remote “silos” = 470m Each ‘silo’ making batches independently Delays and difficult to align production to actual orders – customer lead time 4-6 weeks Customer Lead Time
Pull / Flow • Pull only what the customer orders • Cycle time to make quantity actually needed (x) • Flex capacity by moving operators / adding work-stations • No waiting for other batches • No “Pinching” to fulfil “more urgent” order • Only tactical inventory that is not committed to any specific order • Response time = time for each unit required to move through the final process only Tactical Inventory – Part-built in kanbans & Uncommitted to orders Cell: Elec/Mech/Test/Soak SMT Robotas Flow Solder Customer Demand = x Distance travelled between shared resources and cell = 70m (85% reduction) Customer lead time down to final process time <5 days (subject to volume) Customer Lead Time
Before After Cluttered Poor Lighting Poor Ventilation Search for tools & parts Organised Bright Clean Everything to hand
Kudos+ Workstation Parts for the build Build Instruction Clean & clear place to build the product
Build Instructions Numbers in build instruction match those on the part bins
2 Bin Kanban System Numbers in build instruction match those on the part bins
Signal to Build Empty space is the signal to build
Bin Replenishment Empty bins are placed here for stores to collect Refilled bins are placed here by stores
ATE Test Jig Product can be tested by the person who made it in the cell
Extra Benefits • Improving the process has uncovered more ‘opportunities’ that were hidden • Helped identify key training requirements within the cell • Improved floor space utilisation • New Kanban philosophy • Transactions reduced • Continuous improvement ‘culture’ developing
Benefits - Reduced WIP ~£400 Each 132 Units £52,800
Benefits - Space 274.125m2 20% Overall Reduction
Lean Projects Roadmap • Kudos+ cell - Completed July 04 • IQ Modular - 80% complete • Box build cell • PCB build & test cell • Box configuration & conformance test cell • Kahuna cell - 90% complete • Other product cells - December 05 • Surface Mount line - 2006
History • 1994: Introduced Release 7.1 on a UNIX operating system • 1996: Upgraded to 7.4 • 2002: Upgraded to eb • 2005: Still bloody character screens!
Supply Process- Pre Lean MRP Planned Orders determine what we ACTUALLY Purchase (PO’s) and Manufacture (WO’s) SOP MPS MRP PURCHASE ORDERS WORK ORDERS
Supply Process- Post Lean MRP Planned Orders determine what we MIGHT Purchase (VS) and Manufacture (CRP) Demand Pull (SO, Kanban, Faxban) determines what we ACTUALLY Purchase & Manufacture SOP MPS MRP VENDOR SCHEDULES CRP
PRE LEAN MPS ATP POST LEAN Finite Capacity Scheduling Supply Process- Sales Order Processing
