Reliability predictions are performed to analyze the parts and components of a product
to predict and calculate the rate at which it will fail. A reliability prediction
is one of the most common forms of reliability analyses for calculating failure
rate and MTBF.
New products and significant changes to an existing product may require a calculation
of MTBF before any field data is available. The accepted technique to estimate reliability
is to use the recognized Telecordia or Military models.

- Part Count: failure rate for each part * quantity, includes an environment and quality
factor
- Part Stress: failure rate for each part * quantity, includes an environment, quality
factor, power, temperature, learning factor
