Tableau / Power BI
The two tools that define modern self-service dashboarding
What it is
About Tableau / Power BI
Tableau and Power BI both let analysts connect to data sources, build interactive dashboards, and communicate insight to non-technical stakeholders without heavy coding. Power BI tends to be favoured in Microsoft-centric organisations for its tight Excel/365 integration and lower cost, while Tableau is often preferred for visual polish and flexible exploratory analysis — many analysts are expected to be comfortable with either.

Pro Tip
Pick the tool your stakeholders already use rather than your personal favourite — a technically better dashboard nobody can open or maintain internally has zero business value.
