Systems Diagram is a drawing of the interconnections between all the systems 📝rapidly growing companies use, the map against which a business is instrumented.
A Systems Diagram shows the hosted applications that run a business and how data moves between them. It differs from an 📝App Stack, which is the set of applications used to run a business: the stack lists the tools, while the diagram shows how they connect. Because rapidly growing companies tend to transact through a roughly common set of business systems, one diagram can describe many of them with only small changes.
In a 📝CFO System, the diagram is where the work begins. To 📝instrument a business is to instrument its Systems Diagram: every system on it feeds one data warehouse in 📝BigQuery, and the 📝Integrated Financial Model (IFM) sits at its center, focused on the top of the 📝Instrumentation Pyramid. Setting up 📝Monday Morning Metrics (MMM) starts the same way, with access to the applications mapped in the diagram.
