Data Analyst
A key technical team player is the Data Analyst. Working from the requirements developed by the Business Analyst, the Data Analyst acts as a detective in discovering the specific source data that underpins the requirements. It is often helpful for the Data Analyst to participate in the requirements gathering process to uncover data issues early in the project.

Frequently , business users are not knowledgeable about how their most critical data is actually represented in the source system. The Data Analyst finds the data and documents how various data elements relate to one another. In cases where there is ambiguity or data quality issues, the Data Analyst consults with the BA and business users to resolve the issues.
