In the data assessment phase, consultants evaluate the organization’s data infrastructure, sources, and quality. This involves reviewing databases, files, APIs, or cloud platforms to ensure they can support the Power BI solution. Power BI consulting identify data gaps, inconsistencies, and governance issues, such as compliance or security. They also assess the feasibility of integrating disparate data sources into a unified model. Addressing these aspects early in the process avoids complications during development and ensures the foundation of the Power BI solution is robust and reliable.
