Actually I keep complaining about operational worldbuilding, so here are some recommendations for it:
Ask yourself "what is this organization accomplishing" and "would this organization, as written, accomplish that thing?"
For example, magic academies/schools/universities for adults: what are they training their students for? Is it more like a vocational school or a university? Are students being trained for specific jobs? Is it a training for government? Is it primarily a place to foist the idle rich off to to get them out of the way?
For a military training, is the goal primarily training or a weeding out process? Is it basic training or specialized training? If someone fails out of the training, do they end up in the regular forces or do they fail out of the military entirely?
Ask yourself "how did this practice come to be?"
For example, a trial or competition system: why was this system established? Do the requirements for the trial/competition match what the end result is (e.g., fighting competition to win a fighting position)? If not (e.g., scavenger heart to become the consort), why is that the competition that is used? Do the potential outcomes of the trial (e.g., death) merit the rewards for it?
Ask yourself "if this system is horrible, why do people put up with it?"
For example, a school or organization where people are allowed to attack and/or kill each other: why is it allowed to continue? Why do people send their children or voluntarily join it? If it is mandatory, do people fight against it, and if not, why not?
Oh my gosh. I just found this website that walks you though creating a believable society. It breaks each facet down into individual questions and makes it so simple! It seems really helpful for worldbuilding!
Heads up that this is a very extensive questionnaire and might be daunting to a lot of writers (myself included). That being said, it is also an amazing questionnaire and I will definitely be using it (or at the very least, some of it).
This inspired me to see if Patricia C. Wrede’s Worldbuilding Questions are still online, and not only are they, they’re on the exact same page I saw them on in 1998. Somewhere there’s a binder of the Word doc I made of all of them and the answers I filled in for Baby’s First Fantasy World
