| (programming) | software life-cycle - The phases a software product goes through
between when it is conceived and when it is no longer
available for use. The software life-cycle typically includes
the following: requirements analysis, design,
construction, testing (validation), installation, operation,
maintenance, and retirement. The development process tends to run iteratively through these phases rather than linearly; several models (spiral, waterfall etc.) have been proposed to describe this process. Other processes associated with a software product are: quality assurance, marketing, sales and support. |
