At some point, we're going to have to wrap up the skeleton architecture phase of the project and start implementing real features. We don't want the skeleton phase to drag on for too long because then we'll start making too many assumptions about the reality of our implementation. At the same time, we'll probably want to walk through a few end-to-end scenarios before we move on.
The aim of this section is to provide you with a few high-level points to be on the lookout for in each architectural layer. These aren't strict criteria, but they can certainly help us formulate our own measurements that determine whether or not we've adequately answered our questions about the information architecture by building a skeleton. If we're feeling confident, it's time to go full steam and flesh out the application detail—the subsequent chapters in this book dive into the nitty-gritty of implementing Flux.
