Businesses following the lean software development methodology tends to utilize techniques like paired programming and test-driven development. These techniques are similar to the extreme programming model and are effective in providing continuous improvement and fast delivery of the project. Leaders following the lean methodology allow their teams to come up with their own solutions to specific problems rather than following top-down directives. Additionally, this approach prioritizes team communication and collaboration while developing efficient software.
As the name suggests, the prototype development methodology is the iterative process of developing a simplified prototype of the actual software product to showcase its functionalities and features to the customers. Utilizing this methodology, you can make the essential modifications that are identified by receiving feedback/suggestions from the client before the final deployment of the product.
The overall success of this software development methodology is based on how well the team develops the product and how well they have communicated with the customers. Utilizing this methodology, businesses can easily understand software development requirements and conduct data-driven business analysis. This methodology can solve many issues that often emerge in a traditional waterfall model. It will be proven useful when you need to demonstrate and enhance software functionalities quickly.
Feature-Driven Development (FDD), another agile development methodology, focuses on preventing any kind of misunderstanding that lead to expensive project rework or refinement. This development approach will break down the software development phases and activities into a feature list. For each feature, the team will go through planning, designing, and development, making sure that no feature will last more than two weeks in the development phase.
This methodology is an iterative approach mostly utilized by large development teams following object-oriented modeling in software development. FDD methodology focuses on delivering software through incremental, feature-based iterations. It will help you ensure the development process is well-structured, efficient, and aligned with customer requirements. As FDD aims at continuous software delivery with an efficient client-centric approach, it is suitable for small development projects.
The rapid application development (RAD) methodology prioritizes speed, flexibility, and customer involvement, delivering product prototypes rapidly to the client for their valued feedback. The RAD methodology focuses more on the development teams working on core activities like modeling, prototyping, and testing in the development process. As compared to other software development methodologies, RAD methodology assists in achieving high-quality results and quicker development.
The primary objective of this software development methodology is to accelerate the development process.
