The domain subject matter expert will provide the verification that the approach to the process design is feasible for the staff who perform the end of month accounting procedures. According to the BABOK Guide, a domain subject matter expert is "a stakeholder who has specialized knowledge of a business domain or area of expertise that is relevant to the change or the solution" 4. The domain subject matter expert can provide the business analyst (BA) with the necessary information, feedback, and validation regarding the current and desired state of the accounting process and the impact of the new solution on the staff. The implementation subject matter expert, the operational support, and the project sponsor are also important stakeholders, but they do not have the same level of expertise or authority as the domain subject matter expert in this case.

The BA can avoid the situation of stakeholders presenting conflicting views on how the business analysis process should be conducted by developing a cleaner RACI matrix. A RACI matrix is a technique for defining and documenting the roles and responsibilities of stakeholders in relation to business analysis tasks or deliverables. It clarifies who is Responsible, Accountable, Consulted, or Informed for each task or deliverable1. By developing a cleaner RACI matrix, the BA can reduce ambiguity, confusion, and conflict among stakeholders regarding their involvement and expectations in the business analysis process.
