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? -W On 5 June 2012 19:28, vinodkiran <vinodki...@usa.net> wrote: > 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.
