Allow users to change logic of a Decision Rule

Question

Hi, 
 I have a Decision Rule in my application, in which some calculation is being performed by business logic. Now, customers want to have control over the logic so that they can change it any time. So, how can I show these logic in an Interface, so that customers can change it to their convenience? 
 
 Thanks, 
 Sudip

Currently the decision object is tailored for designers and not business users, so there is not a way to expose it to them in Sites/Tempo. You would have to give the users admin access to the decision object and designer access in Production (/design), which I would recommend against. 
 You could build an Appian interface in Sites/Tempo that mimics the decision object and stores the metadata in an RDBMS table as a workaround.

I really think in order to do what your customers are asking, you'd have to stop using Appian's Decision rule object and recreate it again from scratch, in Appian SAIL code, to expose to your users. What you'd ultimately create is a list of parameters that you could then feed into a gigantic nest of if() statements, where applicable possibly involving the choose() function in there somewhere.
