According to the CCBA® Handbook, an implementation subject matter expert is “a stakeholder who has specialized knowledge of the technologies, tools, or techniques that will be used to implement the solution” (p. 15). They are involved in determining if the requirements can be implemented, as they have the technical expertise and experience to assess the feasibility, risks, and costs of the solution. They can also provide guidance and recommendations on how to best implement the requirements and achieve the desired outcomes. The other options are not correct because:

A. A domain subject matter expert is “a stakeholder who has in-depth knowledge of a specific aspect of the business domain” (p. 15). They are involved in defining and validating the requirements, as they have the business knowledge and insight to identify the needs, problems, and opportunities of the domain. However, they may not have the technical knowledge or authority to determine if the requirements can be implemented.

C. Project team members are “stakeholders who are responsible for the delivery of the solution” (p. 15). They are involved in implementing the requirements, as they have the skills and resources to execute the project plan and produce the solution deliverables. However, they may not have the technical knowledge or authority to determine if the requirements can be implemented.

D. A sponsor is “a stakeholder who authorizes the initiation of a project or initiative and provides the financial resources for it” (p. 14). They are involved in approving the requirements, as they have the decision-making power and influence to support the project or initiative. However, they may not have the technical knowledge or authority to determine if the requirements can be implemented. References:
