I don't like penetration builds on champions like Zac and Amumu. You sacrifice a lot of tankiness by purchasing penetration items. I usually buy only one penetration item and focus the rest on tankiness. However, these builds are viable if there is already another tank on your team, if that happens, then building some damage is the best way to go, otherwise your team will lack damage and probably lose teamfights (DAMAGE is the way to win teamfights, not tankiness - tankiness is necessary, but only when combined with damage) - You still have to build off-tank, however (no full damage otherwilse you will simply explode on teamfights)
