(Slide added—not in evening presentation) Visual Management: What’s Effective? Most effective: • Kanban (visual-flow management) – big thing • 5S – Visual management of thousands of small things that add up to big things • Visual recording of every glitch; organizing same via Pareto, fishbone, etc. Effective: In workplace, visual plots of process trends; displays of employee cross-skilling Less effective: Management metrics on display (highly aggregated, tend to trigger “tampering” with in-control processes) Schonberger & Associates

The Confused State of Lean:Comparing Regions, Industries, CompaniesPDM, Puget Sound APICSWednesday, Dec. 12, 2007 Presenter Richard J. Schonberger 177 107th Ave., N.E., #2101 Bellevue, WA 98004 USA – Tel/Fax +425-467-1143 Schonberger & Associates
This presentation includes research and topical materials incorporated into a forthcoming Richard Schonberger book (John Wiley & Sons): Best Practices in Lean Six Sigma Process Improvement: A Deeper Look . . . with Telling Evidence from the Leanness Studies Schonberger & Associates
Topics and Tendencies • Birthplace of lean has grown fat • U.S., hotbed of lean sliding; Europe doing better • Lean bureaucratized: Fat on administration • Long-term lean: Good in A-D OEM’s, not suppliers; good in automotive suppliers, not OEM customers • Long-term lean: Cash & customer allegiance at compound interest • Lean can do worthy service even if firm going bankrupt • Several ways to get lean, not just the “lean core” • Internal lean getting the attention; external lean promises much more • Inability to keep lean going, hold lean gains. Why? Schonberger & Associates

Lean/Six Sigma: Bureaucratized Elevated to management programs, lots of . . . • Planning • Organization (e.g., Widget University, Deere Production System) • Projects run by professional staff • Name-dropping, jargon, puffery, foreign terms • Management (high-level) goals & metrics • Numerical benchmarks • Follow the leader the fads • All lead to high cost administration (SG&A) Schonberger & Associates
Lean/Six Sigma: Bureaucratized (continued) Less . . . • Work-force involvement & process ownership • Work-force knowledge & commitment • Continuous process data collection • Quick, low-level, low-cost implementations • Innovative approaches • Global best-practice benchmarking(beyond your industry, country) • External (supply/customer pipelines) activity • Results?

“Lean” and Close Surrogate, Inventory • Lean’s main benefits: • Reduce response time—in all things • Find problems before they fester, before trail of causes grows cold • Halt dependence on age-deteriorating item forecasts • Inventory (catch basin for multitude of ills) Each inventory unit . . . • Lengthens discovery time, fouls causal trail (lean/quick beats lot traceback) • Adds lead time (& carrying costs), loses touch with customer & real demand Schonberger & Associates
Improving the Inventory Trends • Inventory is an echo • Inventory reduction as managed goal fails: • Is easily manipulated • Must be seen as result of process improvements in every corner of the greater enterprise Schonberger & Associates
Besides Dana . . . other major vehicular suppliers in or emergent from bankruptcy: Collins & Aikman, Delphi, Dura Automotive, Eagle-Picher, Federal Mogul, Modine, Tower Automotive Collins & Aikman, Eagle-Picher, Federal Mogul, Modine much better off because of many-year compounded lean benefits (insufficient data for Delphi, Dura, Tower) Schonberger & Associates

The “lean core” (basic Toyota system) and other potent ways to get lean Schonberger & Associates
The Lean Core (Partial List) • Physical resources:Plants-in-a-plant/ cells, kanban/pull system, quick setup, small lots/containers, point-of-use tools/materials/equipment • Human resources:Few job classifications, cross-training/job rotation, operator-based quality and maintenance (TPM) • Supplier partnership:Supplier reduction/ certification, external kanban, dock-to-line deliveries Schonberger & Associates
More Pathways to Leanness • Collaboration in pipelines: 2X to 10X greater lean opportunities • Movement of production: To most capable entities (e.g., contract electronic services) • De-proliferation: Ripple effects of DFMA; reduced numbers of product models, customers, suppliers (via intensive 80-20 analysis at ITW) • Process data: Superior to conventional high-level goals & metrics Schonberger & Associates
Still More Lean Avenues • Pipeline Synchronization/Collaboration:Specialty of Dell, Wal-Mart, Zara (Spain), H&M (Sweden), 7-Eleven • Mining Outside Knowledge/Talent/ Experience:Terex acquisition of Genie • 3D Product Design/Planning: In manufacturing, even more in construction • “Big Idea” Business Models: Such as Dell-direct Schonberger & Associates
Inventory Turnover Danaher: Faded lean star? Fluke: Up 3.2% per year, 18 years Acquired by Danaher Schonberger & Associates
Pipelines/Collaboration: Greatest Lean Opportunities Schonberger & Associates
Lean Inside vs. Lean in the Pipelines • Inside: “Lean core” • Perfected mostly at Toyota in 1960s • Gets 90% of companies’ effort • Easy stuff: You own it, see it, measure it • Pipelines: Tight supply/customer chains • Typical manufacturer: 2X to 10X more opportunity to improve than inside • Much supply-chain talk, little progress • Hard stuff; “hot potato,” no one responsible; phony metrics Schonberger & Associates
Lean Supply-Chain Accounting(Re Inter-Company Inventory/Lead-Time) Problem. In numbers-driven companies inventory accounting often main obstacle to lean supply chains. What to do . . . • Gamesmanship. Recognize accounting-based game—getting inventory on other party’s books—just hides the problem • Impacts. Reveal high cost & non-cost impacts of that hiding • Metric. Employ joint inventory to halt the gamesmanship Schonberger & Associates
Lean efforts in logistics pipelines benefit greatly when piggy-backed upon strong lean achievements inside. That is, lean inside provides an anchor of demand predictability and stability for pursuit of lean outside. Inter-Company LeanBuilding on a “lean core” foundation Schonberger & Associates
Lean Inside Lean Supply ChainExample: Graco, Minneapolis (sprayers, compressors) Phase 1. Became among world’s best in “lean core” Phase 2. Closed many branch warehouses • Benefits (expected): large inventory reductions • Greater benefits (unexpected): • Relying on Graco’s quick response (same-day ship for orders in by noon), distributors slashed their inventories • Frequent orders smoothed/leaned out Graco’s production, purchasing, administration, etc. Schonberger & Associates
Why Does Lean Fade? Are There Antidotes? Schonberger & Associates
Lean’s Soft Underbelly • Many smallish practices; no “Big Idea”:Hard to keep all up-and-running; easy to cherry-pick • Focused on wastes:Doesn’t resonate with sales/marketing, finance, senior execs, owners/investors, the public, customers • Needs rivers of process data:Gets trickling streams • Easily bogged down:In analysis (and popular analysis tools) with over-reliance on projects Schonberger & Associates
Operational Tools (Lean Core) Cells/product-focused units Quick changeover Kanban (queue limitation) Cross-training/job rotation 5S/visual workplace Takt-time scheduling One-piece flow Fail-safing Total productive maintenance Supplier partnership Analysis Tools 6 sigma (statistical analysis) projects Kaizen events Value-stream mapping Spaghetti charts Value-add/non-value-add analysis Popular Lean/6-Sigma Tools Schonberger & Associates
Lean’s Native and Potential Strengths • Native: Simple, common-sense, quick-acting, low cost, all-stakeholder beneficiaries Schonberger & Associates
Tapping Lean’s Full Potential • Re-focus: On universal customer wants/ deliverables: ever better quality, quicker response, greater flexibility, higher value • Data recording: Of every process glitch or hiccup—job of all employees • Workteam-based continuous improvement: In parity with dis-continuous project-team improvement • Look outside your industry: E.g., leading-edge retailers, and 3P distributors • Highest-potential gains: External pipelines Schonberger & Associates
“Big-Idea” Business Models Highly Favorable to Lean • Dell-Direct:Spawned many innovations for synchronization of suppliers, customers, Dell • Every-day low prices (EDLP):In its cause, Wal-Mart became global innovator in logistics, IT • 80-20 in all things: ITW cuts to good customers, suppliers, products, parts, plants, machines . . . • Unique business models(easy to understand, hard to deny, flywheel-like momentum, all-stakeholder beneficiaries): They crown Dell, Wal-Mart, ITW as new, global kings of lean Schonberger & Associates
