Rapid Application Development
Rapid-application development (RAD) is a form of Agile software development methodology. It’s used to refer to adaptive software development approaches. In other words, RAD is a popular software development methodology employing various tools and techniques to quickly produce minimally-coded software applications. Unlike Waterfall methods, RAD emphasizes working software and user feedback over strict planning and requirements recording.
In other words, RAD is less talk, more action. Through RAD, Software applications can be developed that are easy to understand and handy to use for the end user. The software can be more usable and has a better chance to focus on business problems that are critical to end users rather than technical problems.
It can focus on the key risk factors and adjust to them based on empirical evidence collected in the early part of the process, thus saving a lot of precious time of the end user and his business.
By focusing on the development of incremental units the chances for catastrophic failures that have dogged large waterfall projects is reduced. In the Waterfall model, it was common to come to a realization after six months or more of analysis and development that required a radical rethinking of the entire system. With RAD this kind of information can be discovered and acted upon earlier in the process.
Compared with traditional methods, the entire process is compressed. As a result, the new system is built, delivered, and placed in operation much sooner.
RAD uses Predefined Prototyping Techniques and Tools to produce software applications.
