I think there should be an article category for production and management (similar to the forum category under "business").

Like this one? https://www.gamedev.net/articles/business/production-and-management/

.... yes. How did I miss that?! I was looking for this category this morning and couldn't find it and was surprised it was missing. User error on my part, obviously.

No worries. It's not quite 1:1, but the idea is for all categories across all areas of the site to have the same taxonomy. Blogs being the exception right now since they're lacking categories..
