• Elements of a good test procedure - THINGS TO KEEP IN MIND

• 
  
  
  
  • It is almost impossible to have too much information in your test procedure - within reason.
  
  
  • Remember - Your CM can always distill your information down to something less than what you provide
  
  
  • Typically they have one “expert” who knows everything and multiple operators who execute the tasks.
  
  
  • You don’t know when your documentation is needed so be thorough
  
  
  
  
  

• Things to include in the documentation - preferably at the top

• 
  
  
  
  • Product/assembly name
  
  
  • Test procedure Rev
  
  
  • List of board revisions that this procedure applies to
  
  
  • Map or image of terms or items
  
  
  • List of ALL software required
    
    
    • Do not assume that your CM has anything
    
    
    • If software version is important make sure this is called out
    
    
    
    
  
  
  • List of ALL files required
    
    
    • Be explicit with the names
    
    
    • Do not be shy with file structure
    
    
    
    
  
  
  • Be consistent
    
    
    • If you call a board X then always call it X
    
    
    
    
  
  
  
  

• Test procedure Meat and potatoes

• 
  
  
  
  • List of required equipment
    
    
    • What can be expected of a CM to have?
    
    
    • Be granular here. All the way down to cables
    
    
    • Do not be afraid to call out amazon links to required items
    
    
    
    
  
  
  
  • Avoid parallel anything - Sequential steps are the best
  
  
  • Always have criteria and be reasonable!
    
    
    • consider how the operator will approach your target and adjust accordingly!
    
    
    • Failures - Let the operator know what to do with a failure
    
    
    
    
    
  
  
  
  • If anything is to be marked or saved be explicit how and where to do it. If there is a sticker or label to be applied show a picture where you want it to go.
