, Software Life Cycle Models
The goal of Software Engineering is to provide
models and processes that lead to the
production of well-documented maintainable
software in a manner that is predictable.
, Software Life Cycle Models
“The period of time that starts when a software product is conceived
and ends when the product is no longer available for use. The
software life cycle typically includes a requirement phase, design
phase, implementation phase, test phase, installation and check out
phase, operation and maintenance phase, and sometimes retirement
phase”.
, Build & Fix
Model
❖ Product is constructed without
specifications or any attempt at
design
Build
❖ Adhoc approach and not
Code
well defined
❖ Simple two phase model Fix
