R and Visualisation Using Power BI — Lesson 4: Operationalization, Refresh, and Troubleshooting

Learning Objectives

• Review package dependencies, privacy levels, gateways, and refresh constraints
• Optimize scripts, visual clarity, reproducibility, and performance
• Diagnose environment, package, data, and rendering failures

Detailed Topics

• Review package dependencies: Review package dependencies, privacy levels, gateways, and refresh constraints
• Optimize scripts: Optimize scripts, visual clarity, reproducibility, and performance
• Diagnose environment: Diagnose environment, package, data, and rendering failures

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Troubleshoot an R-enabled Power BI solution and produce a deployment checklist.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Operationalization, Refresh, and Troubleshooting in a realistic scenario and validate the result with documented evidence.
