Software Life
Span Models
Objectives
is chapter explains the staged model of software life span. After you have read
this chapter, you will know:
◾ e staged model of software life span
◾ e initial development stage and its role
◾ e software evolution stage
◾ e end-of-evolution stage
◾ Servicing, phaseout, and closedown of software
◾ e versioned model of staged life span
◾ Other life span models, including prototyping model, V-Model, and spiral
model
***
e software life span consists of several distinct stages. In each stage, software
needs a different kind of software engineering work, and the life span models offer
a bird’s-eye ...
