Thanks!

This would not be implemented at "the Engine level"; it would be a (more or less) complex
framework similar to what there is now (in Drools) for decision tables. But the evaluation for such
a scorecard is much less predictable than the one for a decision table, which can be
defined in terms of Drools Rule Language conditions, constraints and actions.

If there is a more or less straightforward way of defining constraints and actions from a scorecard,
it might not be so much different from the approach used for decision tables. But is there a
commonly agreed-upon way of deriving the those from a scorecard? Is there a commonly
agreed-upon abstract structure for S.C. as there is one for spreadsheets?

Score Models / Scorecards

The Score Model / Scorecards is a common model used in scoring - a type of
statistical approach, per Predictive Analytics - to allow a subjective score
to be defined against some criteria for some decisioning purpose (eg credit
scoring).

A scorecard represents an assessment, opinion, or prediction about the
customer or prospect. In other decision metaphors such as decision tables or
decision trees, the values for rule conditions and actions are set by the
user. In a scorecard, the properties and values for rule conditions and the
rule action are generated using the values entered in the scorecard. The
attribute scores are summed to return an overall score and the resulting
score. This overall score is then available for use by other rulesets,
functions, decision tables, and decision trees.
