Banay-banay, City of Cabuyao, Laguna 4025 HISTORY AND BACKGROUND RAD Historical Background James Martin (1933-2013) James Martin invented RAD in the 1980s as an alternative to the Waterfall model, which was the prevalent approach at the time. Martin wanted to design a more efficient method to software development that could manage rapidly changing requirements and allow for faster application delivery. The RAD technique was built on iterative development, with the emphasis on swiftly creating a prototype and refining it based on stakeholder feedback. RAD takes a collaborative approach, with developers working closely with stakeholders to determine requirements, design, prototype, create, and test the program. The method is iterative, which means that the client's feedback is used to improve the prototype until the finished product is provided. RAD is very useful for projects with rapidly changing requirements. Background of the Study The RAD model, also known as the Rapid Application Development model, is a software development process that emphasizes quick and iterative release cycles, with the primary goal of providing working software in shorter time frames. Unlike older methods such as the Waterfall model, RAD is intended to be more adaptable and sensitive to user feedback and changing requirements throughout the development process. DEFINITION Rapid Application Development (RAD) is a software development methodology that focuses on rapid prototyping and minimal planning, it focuses on building applications in a very short amount of time or Timebox. 3  Republic of the Philippines Pamantasan ng Cabuyao (University of Cabuyao) COLLEGE OF ENGINEERING Katapatan Mutual Homes, Brgy. Banay-banay, City of Cabuyao, Laguna 4025 This model was proposed by IBM in the 1980s, the main feature of this model is its short time span with a duration of 60 to 90 days only, and also this model can be utilized if the project can be broken down into small modules, and these modules will be assigned to separate teams working independently. OBJECTIVES 1. Speedy Development - RAD focuses on accelerating the software development process through rapid prototyping and iterations, producing a working system quickly—ideal for tight deadlines. 2. Adaptability and Flexibility - This model emphasizes quick adaptation to evolving needs, allowing stakeholders to modify and improve the system based on changing requirements and user feedback. 3. Stakeholder Participation - RAD encourages active participation from end users and stakeholders throughout the development cycle, ensuring the evolving system meets both user and business needs through collaboration and frequent feedback. 4. Improved Interaction - The model enhances collaboration and communication between development teams and stakeholders, reducing misunderstandings through frequent communication and feedback loops. 5. Improved Quality via Prototyping - Early testing and visualization of system components help identify issues, validate design choices, and ensure the final product meets user expectations. 6. Customer Satisfaction - By involving users throughout development and delivering functional prototypes quickly, RAD increases the likelihood of customer satisfaction with the final product. 4  Republic of the Philippines Pamantasan ng Cabuyao (University of Cabuyao) COLLEGE OF ENGINEERING Katapatan Mutual Homes, Brgy. Banay-banay, City of Cabuyao, Laguna 4025 PHASES Developers can add new features and functionalities to the application at any given time. RAD also gets rid of the planning phase in favor of prioritizing speed. Software becomes ready for use in a shorter period. Multiple testing ensures that each application fully meets the users’ needs. These are the five RAD phases: Phase 1: Business modeling At this stage, information flow between different business functions is defined by answering the following questions: What data drives the business process? Who generates the data? Where does the information go? Who processes it? Information is gathered through many business-related sources. This information is combined to create a useful description of how the data will be used when it is processed. Phase 2: Data modeling The information gathered during the Business Modeling phase is analyzed and categorized into different groups (data objects) that are needed to support the business. The attributes of each group are identified, and the relationship between them is defined. Phase 3: Process modeling Process modeling is the third phase of the RAD methodology. Here, all the information groups from the Data Modeling stage are converted into usable data models. These models help extract information from the data objects for making the changes required for proper processing and are responsible for executing business functions. At this stage, changes and optimization in development can be done to increase value and quality. 5  Republic of the Philippines Pamantasan ng Cabuyao (University of Cabuyao) COLLEGE OF ENGINEERING Katapatan Mutual Homes, Brgy. Banay-banay, City of Cabuyao, Laguna 4025 Phase 4: Application generation Here, all the data gathered is coded, and the system that will be used to build the prototype is developed. The data models become actual prototypes that can be tested. Automated tools are used to speed up construction of the software. Phase 5: Testing and turnover This RAD methodology phase ensures less time is spent testing the prototypes created. Every prototype is tested separately to modify the components quickly and to create the best product. The overall testing time is reduced since many of the programming components have already been tested. APPLICATIONS Applications of Rapid Application Development Model (RAD) Why use RAD? Businesses opt for the RAD approach as it requires little focus on the planning phase while enabling the team to design, review, and iterate features and functionalities quickly. RAD is driven by user interface needs and is perfect for application development requiring quick development and deployment. Businesses adopt different types of rapid app development because of their agility, flexibility, and scalability. When to use RAD? When a system needs to be produced in a short span of time (2-3 months), when the requirements are known, when the user will be involved all through the life cycle, when technical risk for the project is low, when high performance is not required, when there is a necessity to create a system that can be modularized in 2-3 months of time, and when a budget is high enough to afford designers for modeling along with the cost of automated tools for code generation. Where to use RAD? RAD is perfect for situations where app development specifically calls for quick development and deployment. It can be beneficial when the project requires a dynamic approach, apps need to be developed quickly, progress needs to be made visible, clients need to be involved in the development, user feedback is readily available, and technical risk is not high. 6  Republic of the Philippines Pamantasan ng Cabuyao (University of Cabuyao) COLLEGE OF ENGINEERING Katapatan Mutual Homes, Brgy.

Banay-banay, City of Cabuyao, Laguna 4025 RAD CASE STUDY EXAMPLE According to the research conducted by J. Lutrania entitled “The Use of Rapid Application Development (RAD) Method in New Students Registration Information System”, the registration process of new students are the most crucial process in any university, especially having a large influx of new students each school year. Their current registration process faced challenges including being time-consuming and inefficient due to extensive paperwork and data entry, resulting in delays and potential errors. Moreover, the lack of real-time data access for the registration committee hindered their ability to monitor progress and make informed decisions. Additionally, students experienced difficulty in accessing information about registration procedures and deadlines, causing confusion and frustration. Their primary objective is to develop a web-based registration information system in order to automate the manual registration process and provide real-time data to the committee using the Rapid Application Development (RAD) methodology. The development process of the web-based new student registration information system involved several key steps. Data collection was conducted through observation of the existing registration process, interviews with registration committee members and students, and analysis of relevant documents. The system was then developed using appropriate programming languages and tools, with a focus on ensuring security and accessibility standards were met. Subsequently, black box testing was carried out to evaluate the system's functionality, ensuring it met the specified requirements by verifying its ability to handle various input scenarios and produce the expected outputs. In conclusion, this case study demonstrates the benefits of investing in technology to improve university processes. The development of a web-based new student registration information system has significantly enhanced efficiency, accuracy, and user experience, ultimately contributing to a smoother and more successful registration process for all stakeholders. 13  Republic of the Philippines Pamantasan ng Cabuyao (University of Cabuyao) COLLEGE OF ENGINEERING Katapatan Mutual Homes, Brgy.
