Figure 3. This figure shows a model for assessing the adequacy of a bank's ongoing evaluation. In the first third of the figure is a three dimensional cylinder labeled Various Source Systems, followed by an arrow labeled Extracted Data. The caption under these two items is "Mapping of source systems to model inputs performed to ensure accuracy and completeness." In the middle of the figure, following the Extracted Data arrow, is a rectangular box containing the word Model followed by three subheads: Theory, Drivers and Assumptions, and Calculations. The caption under this section is "Model structure and assumptions are optimized." Two arrows point from the middle box to two more boxes: Model Output Reports to End Users and Model Output Data Used in Validation. An arrow beneath the latter box points back to the middle box. The caption under the third section is "Back-testing/benchmarking results used to improve model."
