Suggestion on how to group tests (basics, organisations, geography, classifications, etc.)

[stevieflow]

Hi @markbrough

This isn't a proposal to rearrange the tests as they currently stand, but I wanted to share that this has been a useful way to explain the data standard to organisations:

I nice thing about this is that it avoids any advanced category (albeit keeping a basics, which I think we all agree on) - as you can be more advanced / detailed within each area

Thanks
