SİSTEMLERİN ÖMÜR DEVRİ
 bir fikir ile başlar,
 paydaş ihtiyaçlarının sistem mühendisleri tarafından
tanımlanması ile sürer,
 tasarım, entegrasyon ve kalifikasyon ile devam eder,
 üretim, kullanım ve iyileştirme aşamalarından geçer.
 Sonunda sistemin emekliye ayrılması ve imhası ile
tamamlanır.

ÖMÜR DEVRİ SÜRECİ
 The process that defines the life of a system
from an established need to operations
Systems engineering within the life cycle
establishes the configuration and size of system
hardware, software, facilities and personnel
through an interactive process of analysis and
design, with the objective of satisfying an
operational mission need in the most costeffective manner

WATERFALL
•Waterfall Model [Barry Boehm] is inappropriate for systems with large
uncertainties. Local feedback possible but does not account for iterative
nature of development.
