Validation and Verification

(http://antbsd.twbbs.org/~ant/wordpress/?p=202, June 1st, 2006)

每次都搞不清楚 Validation 和 Verification 的差別。今天在這裡查到了，

Verification:

Are we building the product right? To establish the truth of correspondence between a software product and its specification

(veritas = truth)

Validation:

Are we building the right product? To establish the fitness or worth of a software product for its intended mission

(valere = to be worth)
