Step 3: Determine the unadjusted function point count

Although the first two steps are very important in setting the groundwork for your count, and specifying the scope of your count, they are usually performed very quickly, and it is the third step that really takes the majority of the FPA time, and is the heart of the count.

In this step we'll be counting the data functions and transactional functions that yield the unadjusted FP count. As you've seen, to this point we haven't been dealing with any numbers, but we're now ready to start adding them up.

Step 3a: Determine the count resulting from ILF's
Step 3b: Determine the count resulting from EIF's
Step 3c: Determine the count resulting from EI's
Step 3d: Determine the count resulting from EO's
Step 3e: Determine the count resulting from EQ's
