2 Agenda Introduction Digitizing Lean in ERP Ecosystem Problem and baseline metrics Digitized Pull system Digitized TPM Benefits Interactions 2

3 Technology The first rule of any technology used in business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency Enabling Lean manufacturing - through Bill Gates 3

4 Power of Digitization Lean your process improve, eliminate and automate steps Manage by exception Automate information flow from P2E and E2E Integrate people and their roles and functions 4

5 Power of Digitization Customize to individual work styles and decision making Manage and audit production process more effectively and consistently Share production best practices and collaborate on process 5

6 What is Lean? Balanced use of people, equipment and material that gives lowest manufacturing cost Lowest manufacturing cost assumes all wastes is eliminated Supply of material as per customer requirement as and when required with specified quality and quantity Lean = management of Waste 6

7 Drivers of Lean Cost element Drivers Material cost Value engineering Value addition Processing Energy, logistics, cost consumables, equipment Personal cost maintenance Low cost automation, people Finance cost Inventory asset 7

15 Seven step approach for Lean manufacturing Steps Metrics Step 1: Value stream mapping Process ratio in percentage Step 2: Create a flow Step 3: Balance to takt time Step 4: Stabilize the production - TPM Step 5: Improve flow Step 6: Zero defect Single piece flow Ratio between cell bottleneck time and takt time OLE of the cell, Lost cost tree Percentage of missed cards per shift, service level, inventory turnover PPM Step 7: Leveled production Every part every day / every shift / every hour 15

23 TPM through SAP Plant Maintenance module 23

24 TPM Targets P Productivity - Achieve 85% OEE minimum Q Quality - Reduce rejections by 50%. Zero defect products to customer. C Cost - Reduce manufacturing cost by 20%. D Delivery - Supply 100% as per customer requirement S Safety - Achieve Zero accident M Man - Achieve 30 suggestions per employee per year 24

25 Equipment & Functional Location maintenance SMS alerts PM plans & Check list Horizontal deployment Work order management for preventive and breakdown maintenance Breakdown matrix Why-Why analysis Breakdown analysis Notification analysis Plant Maintenance Mean Time Taken to Repair (MTTR) / Mean Time between Failures (MTBF) Linkage to MM and FI for Purchasing and cost centre-wise tracking 25

32 Performance measurement Key measurement task Define measurement variables Perform baseline measurement Perform final measurement Analyze results and calculate benefits If you can t measure, you can t manage it Andy 32

33 Lost cost tree in TPM Prepare loss cost tree for plant Link the losses with financial elements Identify & implement projects to reduce the losses Pillar wise Review the project implementation Link the benefits into business results 33
