Notes Shared EO and EQ Table

Values for Transactions

Like all components, EQ are rated and scored. Basically, an EQ is rated (Low, Average or High)
like an EO, but assigned a value like and EI. The rating is based upon the total number of
unique (combined unique input and out sides) data elements (DET) and the file types referenced
(FTR) (combined unique input and output sides). If the same FTR is used on both the input and
output side, then it is counted only one time. If the same DET is used on both the input and
output side, then it is only counted one time.
For both ILF’s and EIF’s the number of record element types and the number of data elements
types are used to determine a ranking of low, average or high. A Record Element Type is a user
recognizable subgroup of data elements within an ILF or EIF. A Data Element Type (DET) is a
unique user recognizable, non recursive field on an ILF or EIF.

The counts for each level of complexity for each type of component can be entered into a table
such as the following one. Each count is multiplied by the numerical rating shown to determine
the rated value. The rated values on each row are summed across the table, giving a total value
for each type of component. These totals are then summed across the table, giving a total value
for each type of component. These totals are then summoned down to arrive at the Total Number
of Unadjusted Function Points.
