Comment on Why Does DMN Have BKMs? by Ryan
Blog: BPMS Watch - Bruce Silver
Nice explanation thanks Bruce. I understand the need for functions, I have been using those for decades with real world rule/decision implementations. 2 observations on BKM’s and 1 on boxed expressions. 1. Why not just name them functions? creates confusion. Why BKM’s need to be on the diagrams, they get complicated enough already. Why not simply make the function calls part of the decision object? If there are dependencies in the functions, simply have a function diagram that explains that.
Not sure how you can say with a straight face the above boxed expressions are simpler than a scripted formula. If folks are specialist SME’s they will know the formula well. Why not simply use an well known scripting language, there are hundreds already?
I see a huge value in decision dependency diagrams, but the above may create a barrier to DMN adoption.
