JAD Session

JAD Session

JAD stands for Joint Application Development. It's one of those software engineering techniques that some folks with lots of time on their hands sat around and dreamed up. All the design methodologies like this are complicated replacements for a huge dollop of common sense. Sit down with the client and design a paper UI that they can see what the application will look like and behave like. Give the user a chance to work through common scenarios and see if the application will work for them. Keep refining until the user feels the application is doing what they want it to do. As you get functionality implemented, bring the user in and have them work through those scenarios and see if it still works.

On a more serious note, According to Wiki "JAD is a popular Fact-finding technique that brings users into the development process as active participants"

A Typical JAD session agenda:

Project leader: 1) Introduce all JAD team members 2) Discuss ground rules, goals, and objectives for the JAD sessions 3) Explain methods of documentation and use of CASE tools, if any

Top management : Explain the reason for the project and express top management authorization and support.

Project Leader: 1) Provide overview of the current system and proposed project scope and constraints 2) Present outline of specific topics and issues to be investigated.

Open discussion session, moderated by project leader: 1) Review the main business processes, tasks, user roles, input, and output 2) Identify specific areas of agreement or disagreement 3) Break team into smaller groups to study specific issues and assign group leaders.

JAD team members working in smaller group sessions, supported by IT staff: 1) Discuss and document all system requirements 2) Develop models and prototypes.

Group leaders: 1) Report on results and assigned tasks and topics 2) Present issues that should be addressed by the overall JAD team

Open discussion session, moderated project leader: 1) Review reports from small group sessions 2) Reach consensus on main issues 3) Document all topics

Project leader: 1) Present overall recap of JAD session 2) Prepare report that will be sent to JAD team members

Typical JAD's :

• Business Process Modeling JAD
• Business Rules Definition JAD
• Business Data Modeling JAD
• Requirements Gathering JAD
• Quick Fix Design JAD
• Test Planning JAD

To sum it up :

Joint Application Development (JAD) enables a group of people to grasp complex issues quickly and make informed decisions.

The core component of JAD is a structured, facilitated workshop that focuses on creating specified deliverables based on the group's input.

It is an effective tool for planning a project, designing a solution, defining requirements, or any other process that requires consensus-based decision making across functional areas.
