In the traditional systems development lifecycle, end users:

In the traditional systems development lifecycle (SDLC), the role of end users is fundamental, as they provide critical insights and requirements that shape the development process. The correct answer emphasizes that end users are involved in the early stages by sharing their information needs, which helps define what the system must achieve. They also participate in reviewing the progress of the technical team's work, ensuring that the project aligns with their expectations and requirements.

The involvement of end users throughout the process, especially in the requirements gathering phase and subsequent reviews, allows for a better understanding of the system's intended use. This engagement helps to minimize the risks of miscommunication and ensures that the final product meets the practical needs of its users. Their continuous feedback can lead to adjustments and refinements, enhancing the overall quality and usability of the system.

In many development methodologies, especially those following a user-centered design philosophy, active input from users is integrated at multiple stages, going far beyond simply providing initial information and reviews. This active involvement helps identify potential issues early on, which can lead to more effective and efficient project outcomes.
