Used typically in software development, agile concept has made it quite accomplishable for businesses to respond to unpredictability. Throughout the software development lifecycle, direction of the project can be assessed using agile development methodology. In waterfall model, teams have just one chance to set project aspects right while in agile the same is possible continually. Being a classical linear approach, waterfall methodology implements a stage-by-stage procedure for software building that includes requirements analysis, design, implementation, verification & testing, evaluation and maintenance.
Unlike the waterfall method, agile focuses more on values & principles compared to processes. In this way, it calls for minimal risk as in case a glitch occurs during the development cycle, the team will not require going to the start to develop the code again. Also described as incremental and iterative, the agile approach focuses on repetition of work cycles as per requirement. Hence, full chances of project direction re-evaluation are available whenever the development team requires the same. This methodology enables a software development company to build the right product at a reduced developmental cost.
By adopting agile, the critical market relevance of the product is actually preserved. Unlike waterfall approach that stands for predictability, agile rightly stands for adaptability. It focuses on reducing the big picture into small bits and fitting all together at the correct time. One of the biggest pros of agile is that a completely ready-to-launch product is available at the end of each stage of testing. These can be the major reasons why most software development firms are going fast for this approach.
