Business Area Analysis




Menemukan “pengelompokan fungsi dan data bisnis yang
secara natural kohesif” (Martin)
Melakukan aktivitas yang banyak sama dengan ISP, tetapi
lingkupnya lebih dekat ke area bisnis individual

Mengenali sistem informasi yang telah ada
sebelumnya/menentukan kompatibilitas dengan model ISP
baru




Menentukan sistem yang bermasalah
Menemukan sistem yang tidak kompatibel dengan model
informasi baru
Mulai membuat prioritas re-engineering

Pemodelan Sistem dengan UML





Deployment diagrams


Setiap box 3D menggambarkan elemen perangkat keras
yang merupakan bagian arsitektur fisik dari sistem

Activity diagrams


Menampilkan aspek prosedural dari elemen sistem

Class diagrams


Menampilkan elemen tingkat sistem dalah hal data yang
menjelaskan elemen dan operasi yang memanipulasi
data tersebut

These and other UML models will be discussed later
