Context you provide —

  • {{product}} – product name or identifier (e.g., "Widget X")
  • {{annual_demand}} – annual demand in units (e.g., "10,000")
  • {{setup_cost}} – cost per setup or changeover in dollars (e.g., "500")
  • {{holding_cost}} – annual holding cost per unit in dollars (e.g., "2")
  • {{demand_variability}} – optional description of demand variability (e.g., "stable", "seasonal", "highly variable")
  • {{production_capacity}} – optional maximum batch size due to capacity limits (e.g., "2,000 units per batch")

Instructions —

  1. If any required context (annual_demand, setup_cost, holding_cost) is missing, ask for it.
  2. Calculate the Economic Order Quantity using the formula: EOQ = sqrt((2 annual_demand setup_cost) / holding_cost).
  3. If production_capacity is provided, adjust the batch size to the nearest feasible value (e.g., if EOQ exceeds capacity, set batch size to capacity).
  4. For demand variability, discuss how to adjust batch sizes using safety stock or periodic review.
  5. Provide a sensitivity analysis: show how batch size changes if setup cost or holding cost varies by ±20%.
  6. Recommend a batch size and explain the trade-offs (e.g., inventory vs. setup frequency).

Output format — Present the analysis in a structured report:

  • Input Data (table)
  • Optimal Batch Size Calculation (formula and result)
  • Sensitivity Analysis (table showing batch sizes for different cost scenarios)
  • Recommendation (final batch size and rationale)
  • Operational Considerations (impact on capacity, demand variability, and next steps)

Guardrails —

  • Base calculations solely on the provided data; do not invent numbers.
  • If demand variability is high, suggest using a safety stock model but do not calculate without additional data.
  • Flag any assumptions about lead time or ordering costs.

Example — {{product: "Gadget A"}} {{annual_demand: 12,000}} {{setup_cost: 300}} {{holding_cost: 1.50}} {{demand_variability: "moderate seasonal peaks"}} {{production_capacity: 3,000}}

Follow-ups —

  • How would the optimal batch size change if we reduced setup time by 30%?
  • Can you calculate the total annual inventory cost with this batch size?
  • What are the best practices for implementing a kanban system alongside batch production?

  • {{supplier details}}: names, capabilities, and current data-sharing arrangements.
  • {{data available}}: sales, stock levels, lead times, or forecasts you can share.
  • Instructions

  1. Ask for any missing context before starting; list exactly what is needed.
  2. Assess whether VMI is a good fit for the {{product or product line}} and flag risks or prerequisites.
  3. Define the VMI operating model: supplier roles, replenishment triggers, review cadence, and service levels.
  4. Specify the data requirements and the minimum real-time or near-real-time data the supplier needs.
  5. Outline implementation phases, including pilot scope, supplier onboarding, communication protocols, and success metrics.
  6. Identify likely challenges and mitigation steps.
  7. Output format Produce a structured implementation plan with short phases, tables where useful, and a risk checklist. Use practical, concise language for an operations manager. Keep the plan under 350 words. Guardrails

  • Do not invent supplier capabilities or technical specifications; state assumptions.

  • {{inventory_method}} = "FIFO and LIFO comparison"
  • {{product_or_products}} = "electronic components"
  • {{business_context}} = "high inflation, want to minimize taxable income"
