the different software development methodologies

oldest and best known project management methodology is the waterfall methodology, a sequence of phases in which the output of each phase becomes the input for the next. in the sdlc this means the steps are performed one at a time, in order, from planning through implementation and maintenance. The traditional waterfall method no longer serves most of todays development efforts, however it is inflexible and expensive, and it requires rigid adherence to the sequence of steps. its success rate is only about 1 in 10
