I found it interesting how often the word technocrat came up in that article (5). I'm not sure what to read into it, but it is interesting.
Generally the more blatantly a role requires domain knowledge, the more likely it is to be given to a technocrat as opposed to left for political debate.
A technocrat can technically (heh) be a full-time politician, but the idea -in a nutshell- is to limit a position of power to people with relevant education.
Example, you'd require a medical degree to be a Minister of Health and Care Services.
