I am an avid supporter of TOM, but the old way of selecting a solution is just not relevant in today's environment. Agility, speed to market and the fact it exists and can be used, have to carry more weight than any new build option.
Technology is moving at an accelerated pace, faster than some proposed market solutions can keep up with and certainly can't wait for a new build. This is not peculiar to this market. We are in a 4th Industrial Revolution, so our new born babies will see private cars in museums, they will see the end of fossil fuels, they will have AI software like Watson to diagnose diseases and give legal advice.
