Software Design Techniques: Fault Tolerance

• Avoid common mode failures.
  
  
  
• Need for design diversity.
  
  
  
• Same requirements:
  - different programmers?
  - different contractors?
  
  
  
• See also hardware fault tolerance:
  - homogenous parallel redundancy?
  - microcomputer vs PLC solutions?
