the characteristics of the waterfall model (Traditional way of development) 1. Emphasis on document  The output from the previous phase is the input to the next stage, and the document is the only information that is linked to the stage. So many developers seem to be developing documents rather than developing software, because the software's "look" can be seen later in the development. 2, no iteration and feedback. The

Next let's take a look at how agile processes solve waterfall-style process problems one by one: mso-char-indent-count:0;line-height:150%;mso-list:l0 level1 lfo1">Ø deployment process problems: The release time is getting longer and longer. In an agile process, a version is composed of a series of incremental integration, which are developed in an iterative and
