Dynamic Score Calculation
Discover a robust pattern for calculating client's score and risk grade using a library of scoring variables and scorecard structure defined by a Decision Table.
DecisionRules
About the example:
This Decision Flow calculates client's score and risk grade by dynamically executing a list of rules, each representing evaluation of one scoring variable, following the scorecard structure defined by a Decision Table. It also contains score calibration mechanism and enables you to calculate scoring variables when necessary,
Solution components:
- Decision Tables in folder Score Elements, each represents assignment of score points for one scoring variable, thus creating your scoring library
- a Decision Table Scorecard Definition defines which score assignment tables will be used in the scorecard
- a Decision Table Risk Grade transforms calibrated score to a risk grade
- a Decision Flow orchestrates the calculation: sets scorecard coefficients, calculates scoring variables when necessary, executes the Scorecard Definition table to get the list of scoring rules, executes them, calculates the total score, calibrates it and derives the risk grade using the Risk Grade table.
Use this Decision Flow as a robust pattern for defining and execution of your scorecards and simply call it from your credit decisioning system using a REST API…
