Organisations collect more data than ever, but decisions are still delayed by manual spreadsheets, conflicting numbers and reports that nobody has time to read. Business intelligence tools promise a single source of truth, yet the quality of the result depends far more on modelling discipline and design judgement than on knowing where the buttons are.

The Best Practices in Dashboards & BI (Power BI, Tableau) Training Course teaches both the technical build and the thinking behind it. Participants begin by translating a business question into indicators, data requirements and a user story. They then prepare and model data, comparing how Power BI and Tableau handle connections, relationships, calculations and refresh. The design block covers visual perception, chart choice, interactivity, filters and drill-through, and common errors such as truncated axes, overloaded colour palettes and unlabelled metrics. The final sessions address publishing, governance, security, usage monitoring and an approach to maintaining dashboards over time.

The course is lab-based. Each participant builds a complete dashboard in the tool most relevant to their job, rebuilds key views in the second tool for comparison, and leaves with design checklists, a reusable data model pattern and a documented sample report.

By the end of the course, participants will be able to:

• Translate a business question into KPIs, data requirements and a dashboard specification.
• Connect to and transform data using Power Query and Tableau Prep or Desktop.
• Build a star-schema data model with correct relationships and a date table.
• Write DAX measures and Tableau calculations, including level-of-detail expressions.
• Select and format visuals according to data visualisation principles and accessibility needs.
• Optimise report performance and troubleshoot slow or incorrect numbers.
• Publish, secure and govern dashboards using workspaces, permissions and row-level security.

The training suits those who build, commission or maintain reports and dashboards, including:

• Data and business intelligence analysts
• Monitoring, evaluation and MIS officers
• Finance, budgeting and planning analysts
• HR analytics and operations reporting staff
• Report developers moving from Excel to BI tools
• Programme and project managers who rely on performance dashboards
• Researchers and statisticians presenting data to non-technical readers
• IT staff supporting self-service analytics

Participants complete the course with:

• A finished, documented dashboard built on their chosen data set.
• A reusable star-schema data model template.
• A library of tested DAX measures and Tableau calculations for common KPIs.
• A visual design checklist for reviewing their own and colleagues' reports.
• A performance tuning guide covering the usual causes of slow dashboards.
• A governance outline for refresh, access and change control.

The programme is almost entirely hands-on, built around building and critiquing real dashboards:

• Guided labs where each concept is built immediately on a sample data set
• Side-by-side comparison of how Power BI and Tableau solve the same problem
• Design critique sessions reviewing dashboards from participants and public examples
• Troubleshooting drills with deliberately flawed models and measures
• Final project in which each participant delivers and explains a finished dashboard

A CPD-accredited Certificate of Completion from Vision Reach Global Consultancy is awarded to participants who attend the sessions and submit their finished dashboard exercise. It is a training record and not a vendor certification from Microsoft or Tableau.
