What term is used to describe the individual responsible for the daily management and upkeep of a system or product?

The term that accurately describes the individual responsible for the daily management and upkeep of a system or product is operational support. This role typically involves overseeing the functionality and performance of a system to ensure that it operates smoothly and efficiently on a day-to-day basis. Operational support personnel are tasked with monitoring system performance, addressing issues as they arise, and performing routine maintenance tasks, which are critical to the ongoing success and reliability of a product.

In this context, operational support is essential because it focuses specifically on the continuous management of an existing system rather than the development or strategic direction that other roles, like project management or product ownership, might emphasize. Project management typically involves coordinating resources, timelines, and tasks related to new projects or initiatives rather than daily operations. A system architect is generally concerned with the design and structure of systems, focusing more on planning and development rather than day-to-day management. The product owner, while instrumental in guiding the development of a product according to user needs and business value, is not directly involved in the daily operations but instead focuses on maximizing the value of the product backlog and ensuring that the development team is aligned with stakeholders' priorities.

Thus, operational support is the most fitting term for the role responsible for routine management and maintenance of a system
