Software development and life cycle

To determine if everything regarding the model is performing as expected, the developers would use integration and unit testing. As expressed earlier, all models it in different area specifications but the best methodology in the SDLC is the Agile and waterfall. However, the waterfall method is characterized by rigid and already predetermined paths using some defined phases. From the paths of the model, it is clear that it was espoused from the traditional techniques. Hence, I cannot say that the methodology was mistakenly derived since it works for large projects. From observations, the agile methodology puts more weight on teamwork and prototyping alongside feedback structures that may influence the development direction and effort. The differences and abilities of the two methodologies explain the reasons for the transition from waterfall to agile in their production methodologies.
