In the software development, it is common that clients approach development agencies like ours with a product they want to create. If the software development methodologies are either not in place or are not implemented properly, various problems start coming up as the development works progress. The Software Development Life Cycle (SDLC) is the software development world’s spellcheck — it can flag errors in software creation before they’re discovered (at a much higher cost) in successive stages. The methodology should cover all the basic requirements of the software development approach and should have a special focus on testing. The software development in a Feature-driven approach is done a feature by feature, where features are the piece of work that is prioritized by the client and the delivery timeline is of two weeks. If the development of any feature takes more than 2 weeks of time, then it is expected to break down the feature into two parts so that it can be delivered in two weeks of a timeline. Scrum is another way to implement the Agile development methodology. In general, however, SDM is governed by the need to ensure a division of tasks into manageable elements and a process that goes through numerous, expanding iterations. Teams use the agile development methodology to minimize risk (such as bugs, cost overruns, and changing requirements) when adding new functionality. This iterative approach allows the team to find defects early on and fix them which improves the efficiency of the development process. In Scrum, the team, developers and testers collaborate highly to deliver the product. Methodologies also regulate the participation of involved parties outside of the team, like clients and stakeholders.

The heart of the process centers around iterative development — namely, enabling teams to deliver faster … Agile development methodology. Without an SDM to look to during development, the process can easily become chaotic and lead to waste in terms of both financial resources and time. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Agile methodology is used when the team expects changes to the requirements or any increments to the existing functionalities. Software Development Methodology (SDM) is a means by which a program is created through the generation of code and the use of different tools. Software development methodology began to change when developers began working on internet applications. The development work is divided into distinct phases according to the development methodology chosen. So what is a development methodology? The waterfall is very tight and rigid which results in the process being slow and may be costly. Before this SDM can be used, specific goals must be established for a particular process, and the entire development cycle needs to be broken down into different elements.
