software organizations must accept that silver bullets will be a part of their future and should prepare strategies to defend against them rather than to assume their demise. The only plausible defense strategy against silver bullets that I have been able to think of is to assemble an engineering staff that has a natural affinity for eluding these projectiles and one with an innate terror of them. Assembling such a staff, however, would involve an undertaking that is currently quite unpopular: outsourcing. As opposed to China or India, however, my outsourcing plan would focus on a small town in Romania. For it is only in Transylvania where one can assemble a team of those certain someones having an innate fear of silver bullets…werewolves.
