Basics of JAD Methodology
As compared to other primitive SDLC model, Joint Application Development model leads to faster progression of the system development which has better client approval. This model furthermore, is vast when it comes to agile delivery wherein the software products need to be developed as well as shipped in short iterations depending on agreements among the industrial as well as industry stakeholders which are termed as Minimum Viable Product MVP.
Phases of JAD Model Since you have become familiar with the JAD concept, it is time to know about its phases and how the model's design and development approach works: Define Specific Objectives : The facilitator, in partnership with stakeholders, set all the objectives as well as a list of items which is then distributed to other developers and participants to understand and review.

This objective contains elements like the scope of this projected system, its potential outcome, technical specification required, etc. Session Preparation : The facilitator is solely responsible for this preparation where all relevant data is collected and sent to other members before time. For better insight, research carried out to know about the system requirement better and gather all the necessary information for development.

JAD can be a very effective method for reducing the time required to accomplish requirements analysis. Depending on the size of the project, a JAD workshop can take anywhere from one day to a couple of weeks. The facilitator is the person who conducts or moderates the meeting. This person should not be an expert in systems development.

They should, however, possess excellent communication skills and be able to keep the group focused on systems issues. The scribe is the person who can formally document everything that happens in the JAD. This person needs to have a strong knowledge of software development and be acquainted with software to produce documentation such as CASE tools.
Customers are the primary group who will discuss the requirements of the system as well as the scope and boundaries of the project.

Therefore managers and users at all levels, including decision makers, managers of functional areas and operational users should be included in this group. Developers should be present at the JAD, but not as drivers of the session. A JAD session delivers the same outcomes as those of the traditional analysis and design phases of the systems development lifecycle, but with the following potential benefits:.
