Advantages of DSDM model: • Easily adjust to changing requirements. • Providing products quickly. Following the DSDM model is very helpful in providing early partial work solutions, allowing customers to maintain continuous feedback and ensure product success. Customers are actively participating in this model and customer satisfaction is high. Disadvantages of DSDM Model: • As a new model, it is not uncommon or difficult to learn. It is difficult to move from a traditional model of an organization to a DSDM model from the beginning. DSDM model is most appropriate to use when: This model is ideal for projects that need to be developed in a short period of time and cannot be frozen at the start of the project. Requirements can change over time and project resources are fixed, but projects only apply to teams with fixed resources, even as a last resort.

Software Development Lifecycles 2019 Rapid application development is a development model that facilitates rapid prototyping and rapid feedback on long-term development and test cycles. Rapid application development allows developers to quickly complete multiple iterations and software updates without having to run a development plan from scratch each time. The system design phase, along with the technical and detailed design and software architecture, leads to the test phase, software integration and ends with maintenance and support. Rapid Application Development (RAD) is a solution for inflexible processes such as the waterfall approach. Creating software applications in this “old fashion” way usually takes a lot of time.Meanwhile, the requirements changed before the entire system was developed and delivered. This can damage the application. As shown in the diagram above, RAD starts with rapid analysis and minimal planning. Initially, prototypes were built using advanced RAD tools and then tested by end users to provide feedback to developers and designers. Unlike the prototype model, the first built prototype is not reset. Next, complete the same prototype that was built previously and present it to the customer, again providing the developer with feedback and necessary / additional requirements that need to be integrated into the system. Repeat this process until the customer is satisfied. When the customer is satisfied with the system, the testing phase begins. In this model, the testing phase is much simpler because each prototype is tested individually in each phase. Finally, the development team transfers the components to the deployment system's real-time operating environment. In addition, some software usage training will be provided as needed. When to use RAD Methodology • The system must be created in a short time (2 to 3 months). • If you know the demand When a user participates in the entire life cycle Small technical risk Subash Adhikari (HND/ Second Semester Sec-B) 33
