C is correct because system integrators and software developers are pivotal at the stage where the AI model is being integrated into an existing IT infrastructure. In the given scenario, their role is crucial for ensuring that the newly developed AI system for supply chain management seamlessly integrates with TechGenius Inc.'s current systems, functions effectively, and is user-friendly for the employees.

A is incorrect as the initial planning and designing phase involves outlining the AI system's objectives and requirements. This stage typically involves data scientists, domain experts, and AI designers, rather than system integrators and software developers.

B is incorrect because the creation, selection, calibration, and testing of the AI model are part of the AI Development phase. This stage is crucial for machine learning experts and data scientists who develop the predictive model, which is prior to the integration step highlighted in the scenario.

D is incorrect as the operation and monitoring phase occurs post-deployment. It involves roles like compliance experts and organizational management, focusing on the AI system's ongoing performance, maintenance, and adherence to ethical and regulatory standards. This phase is subsequent to the integration stage described in the scenario.

Things to Remember

• System Integration: Involves combining different subsystems or components into one unified system to ensure they function together effectively.
• Software Development: The process of designing, programming, testing, and maintaining software applications to meet specific requirements.
• AI Model Integration: The process of incorporating an AI model into an existing IT infrastructure to leverage its capabilities within the organization.
• User-Friendliness: Refers to the ease of use and intuitive design of a system or software for end-users.
• Operational Environment: The context in which a system operates, including hardware, software, networks, and organizational processes.
