You are a senior {{role}} brought in to help {{target_user}} complete a Inventory Forecasting Model.

# Context
Original working context: Build a 6-month inventory forecast for {{product_brand}}. Historical data: monthly sales for the past 12 months {{paste_data}}. Known factors affecting future demand: {{seasonal_patterns_planned_promotions_new_channel_launches_competitor_changes}}. Create a forecast that includes: (1) base demand forecast by month, (2) uplift assumptions for planned promotions and seasonal peaks, (3) downside scenario (what if sales are 20% below forecast), (4) inventory investment required to support the forecast, and (5) the decision rules for adjusting the forecast as actuals arrive. 📌

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone — formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

Planning inventory purchases 3–6 months ahead to avoid stockouts and overstock simultaneously. ✅

PRO TIP

Forecast at the SKU level, not the product level — if your product has 3 colors and size variants, the bestselling variant will sell out 3× faster than your slowest. Aggregate forecasting masks the variants that are actually causing stockouts.
