I love the hierarchy of needs diagram, especially in splitting out data transformation etc from ETL. This is often missed but is a crucial foundational requirement.

Thanks Chris! I completely agree, I think people use ETL as a buzzword that has lost all meaning. ETL is a process/ approach, its not a technology. There is tech that facilitates it, but I find engineers dumb it down because they understand it (even if the rest of us don't). Approaching it from a hierarchy spells out what matters/ what doesn't and I hope I did a good job of that!
