Azzam Al Rajhi

Quality (Just in time)

• Japanese Philosophy is used now by large Manufacturing Corporations

• The three  primary aims of Just in time:• Long Term Competitive Position: Few trusted suppliers, Long Term

Contract with Key Customers• Improving The efficiency inside the Production Process: Clearing &

Simplifying, Locating, Cleaning, Discipline and Participation• Minimize the Wasted materials, time and efforts

• Pull System instead of push system which is driven by customer Demand. Two method of Pull system• Kanban method: Continuous demand• Hyprid method: Seasonal Demand

Safety – Testing for Safety

1. Engineering Testinga. Real time life testingb. Accelerated life testingc. Simulated User Study -Human factorsd.  V & V Testing for software

2.  ISTA Shipping & Storage Testinga. Environmental Shipping Conditions (Desert or Extreme Cold)b. High and Low Pressurec. Shock - Drop in packaged containerd. Vibration - Simulates vibrations during shipment e. Box Burst Strength f. Box Labeling

3.  Product Safety Testing1. IEC - Test product by itself

i. 1 meter Dropii. Vibrationiii. Operational at elevated and low temperatureiv. Ball Impact testing v. Fluid Ingressvi. EMI / RFI  / ESDvii. Labeling and Manuals

4. UL Flammability & Electrical Shock

3. Fraudulent misrepresentationo Intentional torto Negligent act

4. Strict Liabilityo Defective Product

Liability - Prevention

1. Top Managemento Formulate a company policy on product safety

2. Product Designo Incorporate safety as a design feature

3. Marketingo The product must include warning labels

4. Manufactureo Establish quality controls
