The Project Design

The main Decision Requirement Diagram (DRD) shows how each decision is made.

The input datasets for this model contain,

  • Income
  • Expenses
  • Affordability

Based on those data, we will be determining certain parameters by calculating the average income, expencese and efficiency ratio etc.

Certain decision nodes consist of expressions directly instead of connecting logic documents. The expressions used here are defined in a Business Formula document.
