Reduced system development time. In JAD, information can be obtained and validated in a shorter time frame by involving all participants (or at least a representative set of participants) who have a stake in the outcome of the session.[ 20 ] JAD eliminates process delays and has been shown to reduce application development time between 20% to 50%. [ 18 , 26 ]

| Joint Application Design/Development - Information System Development (or even the broader Information Technology field) is a relatively new discipline compare to matured disciplines like mathematics, physics or philosophy. It is difficult to find an agreed-upon definition on even a widely used term such as JAD. It can mean different things to different people, and it’s constantly evolving. In this article, I will discuss and compare different definition hence different applications of JAD. I will summarize the basic components and benefits of JAD, and guidelines to conduct JAD sessions. I will lastly discuss the new issue with JAD—automation.

Introduction
Origin
Joint Application Design (JAD) was developed by Chuck Morris of IBM Raleigh and Tony Crawford of IBM Toronto in the late 1970’s. In 1980 Crawford and Morris taught JAD in Toronto and Crawford led several workshops to prove the concept. The results were encouraging and JAD became a well accepted approach in many companies. In time, JAD developed and gained general approval in the data processing industry. Crawford defines JAD as an interactive systems design concept involving discussion groups in a workshop setting. Originally, JAD was designed to bring system developers and users of varying backgrounds and opinions together in a productive and creative environment. The meetings were a way of obtaining quality requirements and specifications. The structured approach provides a good alternative to traditional serial interviews by system analysts.[ 1 , 2 ]
