Final answer:
The phase in the SDLC where end users and IT specialists gather and document business requirements is the requirements gathering or analysis phase. It focuses on understanding the scope and creating a detailed requirements document that guides the subsequent design and development phases of the project.
Step-by-step explanation:
The phase in the Software Development Life Cycle (SDLC) that involves end users and IT specialists collaborating to gather, understand, and document the business requirements for the proposed system is known as the requirements gathering or requirements analysis phase. During this phase, stakeholders identify a problem or a need, define requirements and constraints, and use that information to outline the scope and specifications of the new system. It is a critical step in ensuring the success of the project, as it establishes a clear understanding of what needs to be accomplished, often resulting in a detailed requirements document.
Gathering information from various stakeholders, including customers and experts, is crucial at this stage. Techniques such as brainstorming, interviews, and surveys are employed to collect vital details. Once the requirements are understood, the design process, which may include prototyping, testing, and refinement, begins. Feedback from stakeholders continues to play an important role throughout the subsequent phases of the SDLC. Ensuring buy-in from all parties involved, such as researchers, community stakeholders, and end users, is also essential, and their feedback helps to inform and shape the project moving forward.
