1. Place metal shields around the power supplies without holes for air circulation. This will ensure power supply capacitors will dry out and make the power supply fail prematurely. 2. Do not bother with putting thermal conducting paste between heat sink and transistor. 3. Do not bother to solder the heavy components or joints subject to thermal cycling. 4. Make your spare parts very expensive or do not bother with having spare parts available. 5. The following components can be left out during manufacture: protection zener diodes, VDR's, spark gaps, decoupling capacitors, ferrite beads etc. 6. Buy the cheapest components from manufacturers who cannot guarantee the longevity of their product. It is easy to have a CRT fail within three years by using impure materials. This will make the cathodes oxide and reduce the emissions giving a dull, hard to read picture. 7. Fit the so-called head cleaning device to VCR's. This will ensure numerous service calls increasing the customer frustration which will lead them to buy a new product. 8. Make sure that the videotape is laced around the your head during fast forward and re-wind mode on a VCR. This will maximise video head wear and tear. 9. Dispense with EMI/RFI components in the power supplies. As well as producing unacceptable interference this will also mean that the power supply is more prone to damage from voltage spikes. 10. Use the softer plastics rather than the more wear resistant bakelite for kettles and toasters. This will guarantee the consumer will purchase a new product to replace the shabby appliance. 11. Do not use spot welding on your toaster elements. Spot welding makes a reliable connection. Crimped connections will fail within a short period. This is good (for the manufacturer) since spare parts are not available. The consumer will have to buy a new product. 12. Use the cheaper carbon film resistors instead of the more reliable metal film resistor with better voltage ratings. 13. It is best to use a design style which will rapidly look dated. This is another ploy in order to have the consumer purchase the latest style regardless of whether the item is working or not. The next lesson is how to reduce your number of service agencies and how to reduce the number of products the service agencies will repair for you. This will increase the sale of new products by frustrating the consumers efforts in order to have their item repaired.
