What term describes a stakeholder with extensive knowledge of a relevant topic within a business need?

A stakeholder with extensive knowledge of a relevant topic within a business need is called a Domain Subject Matter Expert. This term specifically denotes an individual who possesses deep expertise and understanding in a particular domain or subject area that is crucial to the project or business context. Their insights and knowledge are vital for defining requirements, identifying challenges, and providing solutions related to the business need.

Domain Subject Matter Experts often assist in bridging the gap between technical teams and business teams, ensuring that the end product meets the necessary specifications and business goals. Their authority in a specific area allows them to guide decision-making processes, validate requirements, and ensure that the solutions developed are aligned with the organizational goals.

In contrast, a Project Manager focuses on overseeing the project execution, managing resources, and ensuring timelines are met but may not possess the in-depth knowledge of specific business needs that a Domain Subject Matter Expert has. A Stakeholder Advocate typically represents the interests of stakeholders but does not necessarily have extensive expertise in the subject matter itself. A Business Analyst plays an essential role in gathering and analyzing requirements but may not always have the specialized knowledge of a particular domain that distinguishes a Domain Subject Matter Expert.
