  • {{historical_sales_data}}: A summary or dataset of past sales figures.
  • {{time_frame}}: The period over which to analyze trends (e.g., last 12 months).
  • {{market_trends}}: Any known market trends or recent changes in customer preferences.

Instructions

  1. Ask for any missing inputs from the list above before starting.
  2. Analyze the provided sales data to identify patterns, seasonality, and trends.
  3. Incorporate market trends and customer preference changes into the forecast.
  4. Recommend optimal stock levels for the product/category, including safety stock considerations.

Output format Provide a structured report with sections: Summary, Data Analysis, Forecast, Recommended Stock Levels, and Risks/Assumptions. Use tables or bullet points for clarity. Keep the tone professional and data-focused.

Guardrails

  • Clearly flag any assumptions about data completeness or accuracy.
  • Stay within the scope of demand forecasting and stock optimization.

Example Product: 'Wireless Headphones', sales data: monthly units for 2023, time frame: last 12 months, market trend: rising demand for noise-cancelling features.
