3 Three Pillars of Lean Manufacturing
Human Technological Systems

4 How Pillars Affect SQDCM
Human Technological Systems Safety Quality Delivery Cost Morale

5 What Do We Mean by a System?
These five subsystems are tightly linked… each one affects the others.

6 Human Aspects Consumer Feedback: After purchase surveys
Surveys to potential buyers Employee Feedback: Process problems or improvements (lighter robotic arm design) Integrated into continuous improvement process (Suggestion box, recommendations to supervisors) Employee online surveys Unions: Union representatives / liaisons to assist employees with problems Recognition of employees as the most important asset of the company

7 Human Aspects Training:
Cross training of employees (varied tasks, flexibility of supervisors) Floaters (use in assisting with critical tasks, flexibility supervisors for breaks) Company closed circuit television in break area (covers company news, financial updates, new products) Voluntary participation in continuing education classes = higher morale

8 Technological Aspects
Facility Layout: Open aisles allow managers to monitor processes and employees to detect problems Reduction of wasted movement (i.e. travel distances) Workstation design Ergonomics: Force, frequency and flexion Ergo-Arms, foot pads, roller racks, tilt racks, hydraulic tables Use of employees in the design phase of manufacturing

9 Technological Aspects
Material Handling: Reduction of component stocks (1 1/2 hour operations) at stations Components come in pre-packaged amounts for specific jobs Component packages stored in marshaling areas Reduce the lifting done by the employees Computerized / Wireless acquisition (fork lifts) Mistake Proofing: Color Coding Shape Coding Bar code scanner for all sub-parts (can track all parts by VIN #) Computerized feedback from tools

10 Technological Aspects
Preventative Maintenance: Scheduled services occur at shift changes Unscheduled services conduct repairs upon employees request Testing Measuring Diagnostics Equipment

11 System Aspects Standardization:
Standardize work instruction and directions 5 S’s (Sift, Sweep, Sort, Sanitize and Sustain) SPC Charts Preventative Maintenance Safety (Paint markings, laser indicators) JIT: Orders received at the gate trigger each department Reduction of inventory equates to reduction of storage requirement, increases working capital, decreases bureaucracy Increases responsiveness to customers Temporary bank after human intensive stage

12 System Aspects Computerized Monitoring:
Real-time production statistics Color coded warning system Defects on products are noted and tracked throughout the process KUKA camera tracking system Computerized check of all options (Huntsville check) Continuous Improvement: Non-Value added activities Wastes

13 Definition of Value Added Activity (VA)
An activity that transforms or changes raw material or information to meet customer requirements. Value Added Tests: – The customer must recognize the value (be willing to pay for it) – The product must physically change during the process – The activity must be done right the first time Definition of Non-Value Added (NVA) Activity Any activity that does not transform or change raw material or information to meet customer requirements. Non-Value Added Tests: – Activities that do not meet all of the three VA test rules – Some non-value added work may be necessary

14 Value Added Non-Value Added Machining Stamping Assembling
Designing Customer Service Analysis Painting Sealing/Welding Transportation Inventory Defective material Wait Time Inspecting Testing Correcting Batching Setup

15 The 7 Wastes 1. Product Defects: Defects or repair work
2. Overproduction: Producing too much or too soon 3. Inventory: Excess raw materials or work in process 4. Transportation: Double handling or conveyance of materials 5. Processing: Unnecessary work or processing 6. Waiting: Waiting for parts, materials machines to cycle 7. Motion: Excess walking, bending, or reaching
