For this year’s Halloween I decided to build a DMN decision model that describes how I decide what costume to wear for the 2022 Halloween party – I own four costumes that sit in my cupboard that I select from for each year’s Halloween party. The four costumes are the following…

Apply and improve my Halloween DMN decision model
There you have it, a repeatable DMN decision model for Halloween. This model can not only be implemented each year, but improved as time goes on and my costumes, undoubtedly, wear out!
