The agile and waterfall method are two of the most common methods when it comes to how to approach software development. Every company has a preference when it comes to the method they use and while there are some similarities between the two methods‚ there are also quite a few differences. In Subhajit Datta’s article‚ he mentions that the waterfall method identified core elements within the software development process that have since been adapted by other methods‚ including the agile method.

Introduction to Agile Methodology What is Agile? Agile methodology is an approach to the project management which help to respond to the unpredictability of building software through incremental‚ iterative work cadences‚ known as sprints. This methodology was developed to deal with situation where the waterfall model fails. The biggest drawback of waterfall model is that it assumes that every requirement of the project can be identified before any design or coding occurs. This may always be applicable

Ricardo A. Collado AGILE vs. WATERFALL Agile and Waterfall are two sdistinct methods of software development. The Waterfall model can really be described as a linear model of software design. Like its name suggests‚ waterfall employs a sequential design process. Development essentially flows‚ sequentially from start point to end point‚ along several different stages: Conception‚ Initiation‚ Analysis‚ Design‚ Construction‚ Testing‚ Implementation‚ and Maintenance. In contrast‚ the agile method proposes

They communicate either through e-mail‚ voice mail‚ or direct contact. There is little documentation because of the closeness of the team‚ it’s easier to communicate because of the in your face communication-though

Comparison between Waterfall Model and Spiral Model Software Development includes all the activities starting with an idea for the software to the maintenance of the software. This Software Development includes all the phases from planning to acceptance. There are several models in Software Development Life Cycle‚ but understanding the difference between these models will make me easier to decide‚ which is the right model to be used for developing the project. There are three differences between

which includes water fall‚ spiral and chaos models. Waterfall model is the earliest SDLC approach that was used for software development. In a waterfall model‚ each phase must be completed before the next phase can begin and there is no overlapping in the phases. The outcome of one phrase acts as the input for the next phrase sequentially. Following is a diagrammatic representation of different phases of waterfall model.
