Stages & Life cycle of RAD Model
What is the Rapid Application Development Model? • The rapid application development model is a software development method that delivers results in a short period of time. • In contrast to the traditional SDLC, it compartmentalizes the project into separate functional modules. Each module is driven by user interface requirements and extensive testing. • The RAD Model focuses less on preliminary planning, and more on prototyping and user feedback to refine the final product.
The Five Stages of the Rapid Application Development Model • The RAD Model works in five phases: • Business Modeling: • Information about a company’s business objectives is gathered. This information provides goals for the RAD Model to meet. • Data Modeling: • Information gained in the Business Modeling phase is analyzed to set parameters for the development process. Datasets must be aligned with aims of the business model. Continue…
Process Modeling: The results of data modeling are used to determine the actual process of software development. Methods to add, delete or modify data are determined. Application Generation: Coding is done to create the application. Automated coding tools are heavily employed. Testing and Turnover: Prototypes are tested for efficiency. Each module is tested, keeping in mind extensive user feedback throughout the development process.
Rapid Application Development model vs Traditional Systems Development Life Cycle (SDLC) • In traditional SDLCs, most planning, resource gathering and analysis is done before the start of software development. • User feedback is also gathered after much of the development is finished. Accommodating necessary changes usually causes major alterations to the source code. • In contrast, the RAD model uses iterative and incremental delivery of working models to users. Prototypes at each stage are tested and feedback accommodated immediately.
When should you use the RAD Model? • The RAD Model can succeed when: • The project can be divided into multiple modules, with teams to work on each. • The company/client can devote substantial funding to hire dedicated and skilled designers for each team. • The budget includes the purchase of automated code generation tools. • Clients, users, and designers interact frequently with each other. User feedback is the backbone of the RAD Model.
Advantages of the RAD Model • The RAD Platform has the following benefits: • Due to the project being divided into multiple parts (with separate teams for each), the project is finished much faster. • Debugging and troubleshooting is easier as both major and minor issues for each component are easily identified and resolved. • Constant user feedback means that no major changes must be made after completing the development process. All customer expectations are accommodated in the development stages. • The short development time span means that applications are ready for market without the danger of being obsolete or uncompetitive.
