Hi Margaret,
The Method does not really care whether the prerequisites to a change are in the code or the data. It does however explicitly say that
you should add /any/ prerequisite to a proposed change to your graph.
When it comes to data(base) restructuring the Method itself is agnostic but we believe that fast feedback from automated tests helps in those cases. And if you are restructuring data you probably want the tests to be on 'a different level' than the change itself.
