Considerations that define the waste on the interface:• How often used • Error proneness of

the interface• Delay in processing• Manual effort on the

interface• Cost for processing• Ability to test rainy

scenarios’• Easy of investigating

errors• Support issues• High risk due to not

testing at all or error situations
