Comment on DMN Demystified, Part 5. Key Element 4: Boxed Expressions by bruce
Blog: Method & Style (Bruce Silver)
if..then..else is a FEEL expression. It is very useful in a context, a multi-line boxed expression for a single decision node. (You could jam a decision table into a context entry, but graphically that gets nasty.) Without contexts, end-to-end DRDs will have more than 30 decision nodes, which Larry Goldberg says is the manageability limit. So you really can’t get away from the need for an equivalent to boxed expressions and FEEL. In that case, why have each tool vendor do its own proprietary “equivalent”? Which is what will happen unless customers demand something better.
