Ah, this is really good. This fits perfectly on two of my posts about the IT Flower (link below), relating types of work to supporting technology. Your diagram is an extra layer focused on types of work and learning. Love it!
I'm also happy to see that the diagram shows that even in very structured work there's still non-routine tasks. Just like in typical knowledge work, routine stuff like filling in hourly reports has to be done...
