The waterfall model is a relatively linear sequential design approach for certain areas of engineering designin software development, it tends to be among the less iterative and flexible approaches, as progress flows in largely one direction (downwards like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, deployment and maintenance. Software engineering — software process and software process models (part 2) the agile methods refers to a group of software development models based on the incremental and iterative. The model tends to assist software developer for stating guidelines, templates, and specimens for all features and stages of software development pros: lays high focus on precise documentation.
