Mainly, there are four types of software development methodologies: Agile, DevOps, Waterfall, and Rapid application development. Agile: Agile software development is more flexible. It is carried out in iteration. So, it is easy to make changes in a specific module without affecting or interfering with the entire development process. Various forms of agile development include Scrum, Extreme Programming (XP), feature-driven development (FDD), and Crystal. DevOps Development: The DevOps software development process integrates both the software development team + IT operations for faster and continuous code development. The idea behind DevOps is to improve efficiency throughout the development cycle while minimizing risks and reducing costs. Waterfall: Waterfall is a traditional software development methodology, and it is carried out in a sequential manner. It is essential that each phase in a waterfall model must be fully completed before beginning the next step. Its linear nature makes the development process slow and costly. Rapid application development (RAD): Rapid application development focuses on quick software development with less emphasis on planning. The modules are created based on rapid prototyping and iterative development methods. Other popular software development methodologies are the prototype method, lean method, and dynamic system development model.
