Requirement gathering in Power BI consulting involves detailed discussions with stakeholders to understand business objectives, challenges, and desired outcomes. Consultants identify key performance indicators (KPIs), data sources, and reporting formats. They document user expectations, preferred visualizations, and real-time data needs. Tools like workshops, interviews, and process walkthroughs ensure all requirements are captured comprehensively. Power BI consulting also assess existing IT infrastructure and integration capabilities with Power BI. This phase lays the foundation for a solution aligned with business goals, ensuring that insights are actionable and decision-making is data-driven.
