Understanding Joint Application Development
Joint Application Development in short JAD is the process which is used to design and develop computer based system/solutions. It collects requirements side by side as per business needs while developing new information systems for a company that means JAD involves the client or end-users in designing and development process. It also comprises of approaches for improving the quality of specification and user participation through a successive collaborative workshops called JAD sessions. Since client is involved throughout the development process it leads to faster development times and greater client satisfaction.
