• How is customer acceptance that a product might fail regulated?

  - Warranty
  
  - Protection in law 
  
  Both come down to claim rectify for failures within given time

• What is the downside of warranty etc for customers?

  It does not provide a measure of quality. Limitation of action when it fails multiple times or outside warranty period.

• What are the consequences to the limitation of action when it comes to warranty?

  Manufacturer will suffer
  - loss of reputation, affecting future business.

• Why do we use a time-based concept of quality when it comes to reliability engineering?

  Reliability is concerned with failures in the time domain. -> this is the distinguishing mark between reliable engineering and traditional quality control.

• What aspect does reliability give us?

  Aspect of engineering uncertainty.

• How can reliability be expressed?

  Number of failures over a period

• What is Durability's connection to Reliability?

  Aspect of reliability related to ability of an item to withstand effects of time dependent mechanisms such as:
  - fatigue
  - wear
  - corrosion
  - electrical parameter charger

• How can durability be expressed?

  Minimum time before the occurrence of wearout failures.

• How is durability characterized in repairable systems?

  The ability of the product to function after repairs

• What are the objectives of reliability engineering?

  In order of priority:
  

  1. Prevent or reduce likelihood or frequency of failures
     
  • by applying engineering knowledge and specialist techniques
  2. Identify and correct causes of failures that do occur
  3. Determine ways of coping with failures that do occur
  4. Analyzing reliability data
  • Apply methods for estimating the likely reliability of new designs
