Many folks use the terms JAD and RAD interchangeably, but in reality, they are different approaches altogether. Joint Application Development, or JAD, is a process that brings together business area people (users) and IT (Information Technology) professionals in a highly focused workshop. The advantages of JAD include improvement in the quality of the final product by focusing on the up-front portion of the development lifecycle to reduce the likelihood of errors or required changes that are timely and expensive to correct later on. JAD also results in a shortening of the total application development life cycle time that it would otherwise take to complete a project. But the main aim of JAD is the collaborative, upfront, work effort spent on requirements to get things right; not necessarily to hasten or rush through the project effort or to meet an early delivery commitment. Rapid Application Development, on the other hand, is a software development process that allows usable systems (prototypes) to be built in as little as a few months, but often with some compromises. In a RAD effort, projects are planned with fixed timeframes, sacrificing functionality if necessary. This allows the development team to focus on the pieces of functionality that have the highest business value and to deliver that functionality rapidly.
Since change is often the reason for delays in application development, RAD combats scope and requirements creep by limiting the project's exposure to change by using some niche techniques to shorten the development cycle and limit the cost of change by incorporating it up-front before large investments are made in development and testing. RAD relies on extensive user involvement and Joint Application Design (JAD) sessions. As a side note, the term JAD was coined by IBM in the 1970s and originally stood for Joint Application Design. It has subsequently evolved to Joint Application Development. Hence, the interchangeability of the terms RAD and JAD.
Due to this Digiryte usually have JAD in mind when the discussion is about the workshop-focused sessions to gather requirements and RAD when the discussion is about the actual development process for the applications.
Adapting to changing times is the only way for scaling and we at Digiryte do just that. Be it RAD or JAD, We change to your needs and adopt the ryte development model for speedy and trusted delivery.
