The overall objective is to determine adjusted function point count. There are several steps necessary to accomplish this. While you may not understand the mechanics of the following steps, they will be discussed in great detail in the remainder of the book. The actual sequence or order of steps is not necessary. Many counters will complete step 5 through out the entire count – gathering information as they go:

The unadjusted function point (UFP) count is determined in steps 3 & 4. Steps 3 & 4 are discussed later in this chapter and discussed in detail later in the book. It is not important if step 3 or step 4 is completed first. In GUI and OO type applications it is easy to begin with step 3.

The final function point count (adjusted function point count) is a combination of both unadjusted function point count (UFP) and the general system characteristics (GSCs).
