Explore the Phases of Rapid Application Development Model
RAD referred more to agile application development. It is more focused on the progress of the workflow and its adaptability. It involves less long-term planning of the application development process.
5 Essential Phases of RAD Model for Business Sectors:
The five important phases of Rapid Application development model are analysis, designing, building, and the final testing phase. The steps are further defined, making them more easily understandable. The following essential steps are part of all the RAD models.
Phase 1: Business Modeling
The first step of the RAD model is the Business Modelling step. This step of Business Modelling involves gathering information through many sources linked with business. Then it is Followed by a combination of this information and then labeled so that it can be utilized while being processed and why the information is important in making the business successful.
Phase 2: Data Modeling
This is the second and one of the most important phases of Rapid Application development model. In this data modeling stage, all the information collected in the business modeling phase is examined.
After analysis, the data is divided into different groups, which is useful for the business or company. The quality of each group of data is scrutinized and carefully labeled. Link and usefulness between the groups are defined in the first stage of the RAD model and also maintained in the second phase, which is Data Modelling step.
Phase 3. Process Modelling
In this step of Process Modelling, all the information of the groups which was collected in the Data modeling step is transformed into usable information. During this step, data can also be optimized, transformed, or further defined. Explanation of removal or addition of the data is also done in this phase.
Phase 4. Application Generation
In this step and phases of the rapid application development model, which is the Application Generation step, all the useful information that is collected in the previous steps is coded. The system that will be creating the prototype is formed. Prototypes are created using the data models, which can be analyzed in the next step.
Phase 5. Testing and Turnover
In this step of the RAD model, the testing and turnover phase reduces the overall time in the testing of the prototypes. Each model is tested individually and identified in order to adapt to create an effective product. The components of the models have already been analyzed in the previous steps, so there will be no major issues in the final prototype.
The RAD model of app development can help the client to visualize the final product faster. While creating a prototype of a product, to save money and time, it is imperative to create a product that can be reused for quick changes.
