Inventory Shortage Prevention Plan

Help me build a comprehensive inventory shortage prevention plan for my Shopify store. I have experienced stockouts on [PROBLEM_SKUS] in recent months and it is costing me approximately [LOST_REVENUE] in lost sales.

Please create a prevention plan covering:


  Root cause analysis of recent stockouts:
    
      Pull data on all stockout events in the past [LOOKBACK_DAYS] days.
      For each stockout, identify the cause: demand spike, supplier delay, forecast error, reorder timing, or data error.
      Quantify the impact: lost sales, lost customers, and marketing spend wasted on out-of-stock items.
    
  
  Demand monitoring and early warning:
    
      Set up velocity tracking to detect demand spikes within [DETECTION_DAYS] days.
      Monitor external signals: social media mentions, trending searches, competitor stockouts.
      Create a watchlist of the top [WATCHLIST_SIZE] SKUs that must never go out of stock.
    
  
  Supply chain redundancy:
    
      Identify backup suppliers for all critical products.
      Maintain relationships with at least [MIN_SUPPLIERS] suppliers per key product line.
      Pre-negotiate emergency order terms with [BACKUP_SUPPLIER] for rush fulfillment.
    
  
  Buffer and safety net configuration:
    
      Implement safety stock based on calculated service levels (target: [SERVICE_LEVEL] percent).
      Set up automatic reorder triggers at [REORDER_DAYS] days before projected stockout.
      Create a pre-order or back-order strategy for items that do go out of stock.
    
  
  Communication plan:
    
      Customer-facing: back-in-stock notification signup for out-of-stock items.
      Internal: escalation path when a stockout is imminent.
      Supplier: priority order flag for urgent replenishment.
    
  
  Performance tracking:
    
      In-stock rate target: [TARGET_PERCENT] percent across all active SKUs.
      Monthly stockout report with trend analysis.
      Quarterly review of prevention plan effectiveness.
    
  


Please analyze my current inventory data and produce a prioritized list of actions to implement immediately.
