When you work with SPY you soon find out that most workflows are self-explanatory. Simply because the systems have been developed by the people who use them. And that’s significant when, for example, you need to put your collections and styles into the system. And when you then have to use it.
The SPY concept is that you can always get a quick overview. For example, numbers that are below expectations are in red, and numbers that are good appear in green. This means that you can quickly see where you need to pay attention.
