Scenario Overview
In this scenario we will demonstrate how to quickly and easily set up a Decision Table based around Credit Cards.
For this article it is assumed that you have at least basic familiarity with Decision Tables and/or have read the following articles:
We will use the following custom fields on the Contact entity to decide if a customer is entitled to a Platinum Credit card:
- Annual Income
- Total Assets of Applicant
- Credit Score
If a customer matches any of the scenarios below then they are entitled to a Platinum credit card.
As you can see there are 12 possible combinations each with 3 variables to check which means 36 data points to check.
The easiest and fastest way to achieve the desired functionality is with a North52 Decision Table.
