A customer asks potential vendors – I need a pig that can fly. Whoever can get me one, wins the deal.
Vendor 1 – The Engineer says “There is no such thing as a flying pig. Do not waste our time. We are not interested.”
Vendor 2 – The Geneticist says “I am going to create a new species of pig – one with wings.” He goes to work on a flying pig. He never comes back.
Vendor 3 – The Practical One says “Flying pig indeed! Yes, we can get you one.”
