Power BI provides basic analytics features and supports Python and R for advanced analytics, but these require external tools or coding expertise. Clients often expect seamless advanced analytics without additional dependencies, which can be hard to deliver natively in Power BI. Power BI consultant must set up external environments, which increases project complexity and costs. Additionally, non-technical end-users may find it challenging to maintain such solutions. Power BI’s reliance on third-party tools for advanced analytics limits its usability for clients needing sophisticated statistical models, predictive analytics, or machine learning insights.
