A core problem we see is that those responsible for the transformation have little experience dealing with architecture in an agile way.

Start with some data that you want the system to capture. How many of these values will the system store? For the lifetime of some systems, the initial data frequency will differ quite a bit from the actual real-world data frequency. The model should grow fairly large for non-trivial systems. Most data is composite.
