Joint Application Development is conducted in __________ phases.

Joint Application Development (JAD) is a structured workshop-based methodology for requirements gathering and system design. The process is traditionally divided into five distinct phases to ensure a comprehensive and organized approach. These phases are:

1. Project Definition: Establishing the project's purpose, scope, and objectives.

2. Research: Gathering background information and understanding the existing business processes.

3. Preparation: Organizing the logistics for the workshop, including selecting participants, preparing materials, and setting the agenda.

4. The JAD Session: The core collaborative workshop where stakeholders, users, and developers work together to define requirements and design specifications.

5. Finalization: Compiling, refining, and distributing the final documentation from the session for review and approval.

A. 3: Incorrect. This number oversimplifies the process, likely omitting critical preparatory and finalization stages that are key to JAD's success.

B. 4: Incorrect. This might combine the distinct planning and research phases, which are typically separated to ensure clear scope definition before detailed investigation begins.

D. 6: Incorrect. This would likely involve an unnecessary division of a standard phase, such as separating document creation from the final review and sign-off.

The article describes the JAD process as a structured, multi-phase life cycle, consistent with the five-phase model, covering activities from planning and preparation through the session and post-session activities.
