Make the initial release of your new application small enough that you can get it deployed and providing value in a few weeks to a few months. When building the first module, it’s hard — but essential — to resist feature creep. The measure of success for the first release is how quickly you can do it, not how much functionality is in it. Typically, this is achieved by using the “vertical slice” approach in which we build small increments of functionality end-to-end across the whole technology stack.
