Who can be considered a domain subject matter expert?

A domain subject matter expert (SME) is an individual who possesses a deep understanding of a specific field, industry, or area of expertise. This includes knowledge about the nuances, best practices, regulations, and potential challenges within that domain. Their expertise allows them to provide insights and guidance that are valuable for projects that require specialized knowledge, helping to ensure that the work aligns with industry standards and the needs of stakeholders.

In this context, the option referring specifically to a "Domain Subject Matter Expert (SME)" represents the ideal candidate who is recognized for their specialized knowledge. SMEs are essential in various phases of projects, particularly in requirements gathering, validation, and design phases, ensuring that the solutions developed are practical, feasible, and aligned with domain specifics.

The other roles mentioned, such as Change Manager, Business Analyst, or IT Support Staff, while they have their own important functions, do not possess the same level of specific domain expertise that a dedicated SME does. They may have insights related to their roles, but they do not focus solely on the specific complexities and requirements of the domain in question as a domain SME would.
