This kind of development methodologies are only concerned with the software development process, so it does not involve any technical aspect of, but only concern with proper planning for the software development. There is easy management due to the rigid nature of the waterfall model with each stage having a separate review process. The agile development process delivers a high-quality output because small iterations involve easy test and maintenance with fewer errors. The big secret nobody is saying out loud is that there are no differences between Agile and Lean. It functions by the early identification and reduction of risks in a project. Disadvantages . This is another iterative methodology but in combination with object modelling. The Waterfall and Lean models are as different as a mole and a gazelle. Those modern methodologies have come to replace good old Waterfall and RUP (Rational Unified Process) models. The main aim of this model is to create a fully-functional product and cut the cost of software non-essentialities. 2. The prototype methodology is the software development process which allows developers to create only the prototype of the solution to demonstrate its functionality to the clients and make necessary modifications before developing the actual application. The longer the project continues, the greater the dangers of the initial planning becoming out of date. Software development is a complicated process from both perspectives and it is important to understand the pros and cons, common problems, and when to use an agile methodology. Not applicable for projects that tend to have modifications in the production process. The resulting features are always greater than the inputs.
