From several literature reviews that have been collected, the author wants to explain that In this study, we will discuss the application of the Joint Application Design (JAD) Method in developing a Website-Based Women's Clothing Sales Information System at Aldisa Boutique.
We will explore how the JAD Method can be used to identify business needs, design system features, and implement optimal solutions.Through this study, it is hoped that it can provide valuable insight into the development of a successful information system in the online women's fashion sales industry and help make it easier for consumers to order clothes.

Joint Application Design (JAD) Method
Joint Application Design (JAD) is a method that prioritizes user commitment in determining needs, and requirements and designing a system.Joint Application Design is carried out and implemented by forming a joint team from all project stakeholders, who work together in the form of a forum.discussions and meetings in person or in a virtual way [8] The Joint Application Design (JAD) method is a collaborative approach to information system development that actively involves various stakeholders throughout the design process.This method aims to create a deep understanding of the business needs and desires of users by involving them in discussions, problem-solving, and decision-making.

Main characteristics of the JAD Method
• Active Participation: Stakeholders who are actively involved in the JAD session, including management, end users, system developers, and other stakeholders.
• Professional Facilitation: JAD sessions are led by a trained facilitator to lead discussions, and encourage collaboration between participants.• Structured Sessions: JAD sessions have a structured and sequential agenda, starting from understanding the business context to formulating decisions about system design.• Shared Decision Making: The primary goal of a JAD session is to achieve consensus among stakeholders about business requirements, system features, and solution design.• Use of Techniques and Tools: The JAD method can involve the use of a variety of techniques and tools, such as business process analysis, flow diagrams, prototypes, and design sketches.• Documentation of Results: Decision discussion results from JAD sessions are well documented for reference during the system development phase.

JAD Implementation Process
Picture 2 above depicts the practical application of the Joint Application Design (JAD) method, a collaborative approach used to gather requirements for a system.In this instance, the implementation occurred virtually through a Zoom meeting.This modern adaptation allowed stakeholders to convene remotely and engage in discussions regarding the necessary features and functionalities for the system under development.
Through the virtual platform, participants were able to streamline communication and ensure all key stakeholders could contribute to the requirements gathering process.By leveraging technology such as Zoom, geographical barriers were overcome, enabling efficient collaboration regardless of participants' locations.This approach facilitated a comprehensive exploration of the system's needs and requirements, ensuring that all perspectives were considered in the design phase.
The utilization of Zoom for the JAD session exemplifies the adaptability of modern technology in facilitating collaborative efforts, even in the realm of software development.Virtual meetings not only enhance accessibility but also promote inclusivity by accommodating diverse schedules and locations.As organizations increasingly embrace remote work practices, such virtual collaboration tools play an integral role in driving efficient and effective project outcomes.(users) and a system.In the scenario described, there are two primary actors: business owners and consumers.The use case diagram outlines the functionalities accessible to each actor within the system.
