**Description:** Joint Application Development is a methodology that promotes active collaboration between the client and the developer during the design and development process of software applications. This practice is based on the premise that client involvement not only improves the quality of the final product but also ensures that user needs and expectations are effectively integrated into development. Through regular meetings, continuous feedback, and iterative prototypes, both parties can adjust and refine the product in real-time. This methodology fosters open and transparent communication, helping to minimize misunderstandings and align project goals. Additionally, Joint Application Development fits well in agile environments, where changes are frequent and software is expected to evolve over time. In summary, this methodology focuses not only on delivering a product but on building a strong relationship between the client and the development team, resulting in more effective and satisfying solutions.
**History:** Joint Application Development (JAD) emerged in the 1970s in response to the need to improve communication between software developers and end users. It was popularized by IBM, which implemented this methodology to facilitate the development of information systems. Over the years, JAD has evolved and been integrated into agile approaches, where continuous collaboration is essential for project success.
**Uses:** Joint Application Development is primarily used in software project management to ensure that client requirements are understood and properly implemented. It is common in custom software development projects, where customization is key. It is also applied in prototype creation and in planning complex systems, where constant feedback is crucial.
**Examples:** An example of Joint Application Development can be seen in the development of enterprise management systems, where developers work closely with business managers to define specific features. Another case is mobile application development, where JAD sessions are held to define user experience and desired functionalities.
