"What are the best practices that should be followed when documenting a Power BI report?"

**The Hawthorne Effect**: When documenting a Power BI report, it's essential to consider the Hawthorne Effect, which suggests that individuals placed on a special diet will exhibit beneficial changes in their dietary habits and health, merely because they are part of the experiment (Lysakowski, 2012).

This concept applies to documentation, as it highlights the importance of considering the human factors when creating reports to ensure they are user-friendly and effective in conveying information.

**80/20 Rule**: When designing reports, it's crucial to follow the 80/20 rule, where 80% of the work is dedicated to 20% of the problems.

This Pareto principle guides prioritization and simplification of complex issues in reporting (Hooker, 1997).

**ROW-Level Security (RLS)**: Row-Level Security (RLS) is a Power BI feature that enables filtering data based on user permissions.

This capability ensures that users only see the data they are authorized to access, maintaining data confidentiality and integrity (Power BI, 2022).

**SWITCH TRUE**: When using Switch True in Power BI reporting, it's essential to avoid nested IF statements, as they can make the code harder to read and maintain.

This best practice ensures easier debugging and updates to the reports (Power BI, 2022).

**Cognitive Load Theory**: When designing reports, it's vital to consider Cognitive Load Theory, which suggests that the human brain can process only a limited amount of information at a time.

Reports should be designed to minimize cognitive load, making it easier for users to comprehend the information (Sweller, 1988).

**Visualization Best Practices**: charts and visualizations should be designed to provide insight and clarity, avoiding complex or hard-to-read graphics.

Using simple and intuitive visualizations can significantly improve user comprehension (Tufte, 1983).

**Documentation as a Service**: Power BI provides an internal documentation capability, allowing for automatic documentation of Power BI models and reports.

This feature simplifies the documentation process and ensures consistency across reports (Power BI, 2022).

**Collaboration and Knowledge Sharing**: When documenting reports, it's essential to consider the importance of collaboration and knowledge sharing.

Documenting reports can facilitate knowledge transfer between team members and stakeholders, ensuring that critical information is shared effectively (Knapp, 2016).

**Data Modeling and Visualization**: Accurately modeling and visualizing data is crucial for effective reporting.

Using certified visuals and simplifying complex data can significantly improve report usability and comprehension (Power BI, 2022).

**Human-Centered Design**: Documenting reports should prioritize human-centered design principles, focusing on user needs, simplicity, and intuitive navigation.

This approach ensures reports are user-friendly and effective in conveying information (Nielsen, 2003).
