Finding the right project is key for the first application that you move to the platform... So, you are going to want to pick an application that potentially has a little less risk, maybe it's a digital marketing application, maybe it's something that the customer has never had a chance to build before. So, in that new application that doesn't require a massive re-write and something that has the right executive mind share within the company, it's valuable to the company but also has a little bit less risk. You probably don't want to pick the first app to be the mission critical business app that everybody uses, but once you get that first application, then it's easy for you to go back to the customer and have a the second app, and a third, and a fifth, and a tenth and pretty soon you're running an entire portfolio.
