Like all components, EOs are rated and scored. The rating is based upon the number of data elements (DETs) and the file types referenced (FTRs). The rating is based upon the total number of unique (combined unique input and out sides) data elements (DETs) and the file types referenced (FTRs) (combined unique input and output sides). DETs and FTRs were discussed earlier in this section. The table below lists both the level (low, average or high) and appropriate score (4, 5 or 7).
| File Types Referenced (FTR) | Data Elements | ||
|---|---|---|---|
| 1-5 | 6-19 | Greater than 19 | |
| Less than 2 | Low (4) | Low (4) | Average (5) |
| 2-3 | Low (4) | Average (5) | High (7) |
| Greater than 3 | Average (5) | High (7) | High (7) |
