It's a traditional testing methodology. The idea is that you have activities such as "Model Requirements", "Design", ... on one side of the V and then testing categories such as ...

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
