it is a type of incremental model. the developments are time boxed, delivered and then assembled into a working prototype. business modeling: the information flow is identified between various business functions. data modeling: information gathered from business modeling is used to define data objects that are needed for the business. application generation: automated tools are used to convert process models into code and the actual system.

rapid-application development (rad), also called rapid-application building (rab), is both a general term for adaptive software development approaches, and the name for james martin’s method of rapid development. prototypes are often used in addition to or sometimes even instead of design specifications. other approaches to rapid development include the adaptive, agile, spiral, and unified models. rapid application development was a response to plan-driven waterfall processes, developed in the 1970s and 1980s, such as the structured systems analysis and design method (ssadm). software can radically change the entire process used to solve a problem. as a result, knowledge gained from the development process itself can feed back to the requirements and design of the solution.
rad approaches, on the other hand, recognize that software development is a knowledge intensive process and provide flexible processes that help take advantage of knowledge gained during the project to improve or adapt the solution. prototypes had several advantages over traditional specifications: starting with the ideas of barry boehm and others, james martin developed the rapid application development approach during the 1980s at ibm and finally formalized it by publishing a book in 1991, rapid application development. it is important to distinguish between rad as a general alternative to the waterfall model and rad as the specific method created by martin. these ideas were further developed and improved upon by rad pioneers like james kerr and richard hunter, who together wrote the seminal book on the subject, inside rad, which followed the journey of a rad project manager as he drove and refined the rad methodology in real-time on an actual rad project. the rad approach also matured during the period of peak interest in business re-engineering. the idea of business process re-engineering was to radically rethink core business processes such as sales and customer support with the new capabilities of information technology in mind. the rapid prototyping approach of rad was a key tool to help users and analysts “think out of the box” about innovative ways that technology might radically reinvent a core business process.
rad model or rapid application development model is a software development process based the phases in the rapid application development (rad) model are: what are the software development models? a software project can be implemented using this model if the project can be broken down into, spiral model in software engineering, spiral model in software engineering, prototype model in software engineering, waterfall model in software engineering, incremental model in software engineering. rapid application development (rad) describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery. the rad model is, therefore, a sharp alternative to the typical waterfall development model, which often focuses largely on planning and sequential design practices. rad should be used only when a system can be modularized to be delivered in an incremental manner. it should be used if there is a high availability of designers for modelling. it should be used only if the budget permits use of automated code generating tools.
rad is a linear sequential software development process model that emphasizes a concise development cycle rapid-application development (rad), also called rapid-application in general , rad approaches to software rapid application development (rad) is a form of agile software development methodology that,
