Rapid Application Design
- 2. Rapid Application Developmen t is a systems development methodology that was developed to respond to the need to deliver the systems very fast
- 3. When should we use RAD? -Project Data Scope Business Objectives Is well defined and narrow -Project Decisions Can be made by a small groups -Project Technical Requirements Reasonable Ad within capabilities technology to be used
- 5. Requirements Planning Phase -Systems Analysis(SDLC) -Business needs -Project scope -Constraints -Systems requirement Rapid Application Development
- 7. Rapid Application Development User Design Phase -users interact the systems analysis and develop models and prototype
- 8. Rapid Application Development Construction Phase -users continue to participate and can still suggests changes or improvements as actual reports are developed
- 9. Rapid Application Development Cutover Phase -it resembles the final tasks and the sdlc implementation stage
- 10. Identify Objectives and Information Requirements Work with Users to Design Systems Build the System Introduce the System User Feedback Use Input from Users

- -the project is suitable for RAD if it has focus scope where the business objectives is well defined and narrow -also, the project is suitable for RAD if the decisions can be made by a small number of people the project team must be small like 6 people or less -the project is suitable for RAD if the project technical architecture is defined and has a clear, the key for technology component is in place and tested ProjectTechnical Requirement are reasonable and within capabilities of the technology being used Some developers are looking at RAD as a helpful approach in new ecommerce, Web-based environments in which so-called first-mover status of a business might be important. In other words to deliver application to Web before their competitors, businesses may want their development team to experiment with RAD
- element of the Systems Planning and systems Analysis phases of the sdlc(systems development life cycle) Business needs, project scope, constraints, system requirement In the requirements planning phase, users and analysists meet identify objective of the application or system and to identify information requirements arising from those objectives. This phase requires intense involvement from both groups; it not just signing off on proposal or document.
- The RAD design workshop is a phase a design-and-refine phas that can best be ccharacterized as a workshop. During the Rad design workshop , users respond to actual working prototypes and analysists refine designed modules using some of the software tools mentioned later based on user responses. The workshop format is very exciting and stimulating, and if experienced users and analysists are present, there is no question that this creative endeavor can propel development forward at an accelerated rate
- This part incorporates both the user phase and the construction phase into one, because highly interactive and visual nature of the design and refine process is occurring in an interactive, participative way.
- In the construction Phase many different activities are going on. Any design that were created in the previous phase are further enhanced with RAD tools. As soon as new action, comments and review. With RAD tools, analysts are able to make continuous changes in the design of applications.
- In this part of systems are tested and then introduced to the organization. By this time, the RAD design workshop will generated excitement, user ownership, and acceptance of the new application.
- The RAD approach allows for quick development. compared with traditional methods the entire process is compressed as a result the new system is built delivered and placed in operations
