Best Practices

• Test prompts with a small data sample to validate output structure before scaling.
• Keep prompts focused on a single analytical objective per prompt to avoid ambiguous results.
• Include explicit output formats (pivot, chart, table) to ensure ready-to-use results.
• Use placeholders for data fields to adapt prompts across different shop setups.
• Review outputs for data quality and bias; validate with a quick manual check if needed.

Common Mistakes to Avoid

• Asking for too broad analysis without defined outputs or formats.
• Using vague terms like analyze profitability without specifying metrics and time frame.
• Not constraining the output to Excel-friendly formats, causing formatting issues in reports.
• Neglecting data quality checks or data definitions, leading to unreliable results.
• Overusing generic phrases that require user invention instead of providing placeholders or examples.
