size estimation, it is suggested that we count the functional processes identied,
classify them into few categories according to their complexity, and assign them an
experimentally determined average functional size. is variant resembles the use
case points approach, except the mean values assigned to functional processes are
not prescribed.
3.4.3 Use Cases
Use case modeling gained huge popularity within the software industry as the
software functional requirements, as well as the business modeling mean. e fact
that the approach does not enforce particular development methodology made it
easier to adopt. ere are several signicant
