Validation vs. verification
¾ Validation: process of evaluating a system or component during
or at the end of the development process to determine whether it
satisfies specified requirements
– Validation: Are we building the right product?
¾ Verification: the process of evaluating a system or component to
determine whether the products of a given development phase
satisfy the conditions imposed at the start of that phase
– Verification: Are we building the product right?
