Understanding Failure Theories
No product or service lasts forever, but how do we determine or project when a particular item may fail and why is this important?
Watch the following video for ideas regarding certain “things” and their failure calculations:

Relate these concepts to your work experience and provide an example of a product or service that the company sold or supported. How did they calculate failure rates?
There are a number of factors that can affect the lifespan of a product or service. Some of these factors are:
- The materials used in the product. Some materials are more durable than others. For example, a product made of metal will typically last longer than a product made of plastic.
- The way the product is used. A product that is used heavily will typically wear out faster than a product that is used lightly.
- The environment in which the product is used. A product that is exposed to harsh conditions, such as extreme temperatures or moisture, will typically wear out faster than a product that is used in a more moderate environment.
- Safety. If a product is known to have a high risk of failure, it can be recalled or redesigned to prevent injuries.
- Reliability. If a product is known to be reliable, it can be used in critical applications, such as medical devices or aircraft.
- Cost. If a product is known to have a short lifespan, it can be designed to be easily replaced or repaired.
- Inspect the product regularly for signs of wear and tear.
- Review the product's warranty and service information.
- Keep up-to-date on recalls and safety alerts.
- Be aware of the product's intended use and environment.
- Store the product properly.
