Nice! I didn't know of DMN (https://camunda.com/dmn/ https://camunda.com/dmn/). Are there any detailed literature (articles/books/etc. on this and related decision techniques) that you can point us to ? PS: I had posted another related article which you might find interesting - https://news.ycombinator.com/item?id=38822320 https://news.ycombinator.com/item?id=38822320

  BPMN and DMN are mature and standardized technologies for enterprises.
