Design for X (Design for failure (planning for failure (redundant systems,…

- - - - minimal impact on cost, weight and system function
    - - test the design
        
        failure detection
        
        verify severity of failure
        
        analysis for failure types
    - - Failure modes and effects analysis (FMEA)
        
        severity
        
        detection
        
        effects of failure mode
        
        cause of potential failure mode
        
        failure mode
  - - - monitor the input and output system
    - - acting upon the system on a periodic basis
    - - occurrence rating
      - detection rating
      - severity rating
  - - - if one part fails, whole system will stop
    - - backup system that can be use to perform primary system
      - failover / switchover
    - - retain sufficient operational capability for save mission continuation
    - - take turn , so as not to get overloaded
- - - - upon failure, some critical functions are still performed
    - - additional components or system configured in parallel or series, take over the principal function of the failed component or system
    - - design to operate for their entire predicted useful life without breakdown or malfunction
- - - - redesign components to eliminate process steps
      - choose the appropriate economic scale for the part process
      - understand the process constraints and cost drivers
      - standardize components and processes
      - reduce the cost for assembly
