Waterfall model followed in the sequential order, and so project development team only moves to next phase of development or testing if the previous step completed in agile description of project, details can be altered anytime during the sdlc process which is not possible in waterfall method. Sdlc, software development life cycle is a process followed for a software project, within a software organization it consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software the life cycle defines a methodology for improving the quality of software and. The agile methodologies stand in contrast to the traditional waterfall methodology, where all the requirements are initially analysed and documented before the development begins while in the agile development methodology enables assessment of project direction throughout the development lifecycle.
Waterfall, agile 1 waterfall methodology is sequential and linear agile methodology is increamental and iterative 2 requirements have to be freezed at the beginning of sdlc requirements are expected to change and changes are incorporated at any point 3 working model of software is delivered at the later phases.
