  1. RAD methodology Created by: Hussein Rezaee

  2. What is RAD? Rapid Application Development (RAD) refers to a type of software development methodology that uses minimal planning in favour of rapid prototyping. It is a development lifecycle designed to give you a lot quicker advance and higher quality results. It has four essential aspects such as methodology, people, management and tools. As well as, Requirements Planning, User Design, Construction, and Implementation, these are the four stages of lifecycle. It used in an organisation for developing software.

  4. When it was developed • Rapid application development developed in between 1970s - 1980s, included the Structured Systems Analysis and Design Method and other Waterfall models. • They had 1 issue with previous methodologies • Applications was taking too much time to build the requirement changed before the system was complete. • resulting in unlikely or even unusable systems.

  5. Example of RAD IBM Personal Computer

  6. Four Essential Aspect for RAD

  7. METHODOLOGY The challenges facing software development organizations can be summarized as more, better, and faster.

  8. PEOPLE The success of Rapid Application Development is contingent upon the involvement of people with the right skills and talents.

  9. MANAGEMENT Achieving high-speed development is a complex process. Systems will not be developed and deployed rapidly if organisation problems stand in the way or if users are not appropriately involved.

  10. TOOLS The RAD methodology uses both computerized tools and human techniques to achieve the goals of high-speed and high quality.

  11. 4 stages of lifecycle Requirements Planning Defines the business functions and data subject areas that the system will support and determines the system’s scope. User Design This stage uses workshops to model the system’s data and processes and to build a working prototype of critical system components. Construction Completes the construction of the physical application system, builds the conversion system, and develops user aids and implementation work plans. Implementation Final user testing and training, data conversion, and the implementation of the application system.

  12. Advantages The application will fully meet customer requirements and therefore customer satisfaction is high. shortens the time required to produce the product. Flexible and adaptable to changes.

  13. Disadvantages Method cannot be a success if the team is not sufficiently motivated and nor is unable to work cohesively together. It may be difficult for many important users to commit the time required for success of the RAD process.

  14. Suitable for System administration RAD is suitable for System Administration, when IT company developing Network Laps for student to teach them such as Nepean college (for example, built a lab with 15 computer, cabling, connecting workstation to the server. if they follow the process of RAD methodology it makes their job easier and can be finish in short time.
