For highly perishable items (berries, spinach, herbs, avocados), do not try to maintain stock. Buy only with specific plan to eat within 48 hours.
The mistake: “I want to always have spinach on hand.” This guarantees waste. You buy backup while first bag is half-full. Backup slimes over.
The fix: Remove these from general inventory. These are meal items, not stock items.
The rule: Only buy if you have specific plan to eat them in next 2 days. If you run out? You run out. Better to have no spinach for 2 days than throw away bag of slime every week.
Which Items Get This Treatment
Just-In-Time category:
- Leafy greens (spinach, lettuce, arugula)
- Fresh herbs (cilantro, parsley, basil)
- Berries (strawberries, raspberries, blueberries)
- Avocados
- Tomatoes (vine-ripened)
NOT Just-In-Time: Items with 2+ week shelf life can use Two-Bin System or Freezer Bridge.
The Mental Shift
From: “What vegetables should I have?” (stock mentality) To: “What vegetables am I using this week?” (meal-plan mentality)
North: Where this comes from
- Just-In-Time Manufacturing (make/buy only when needed)
- Lean Principles (eliminate waste through timing)
- Pull System (demand triggers purchase)
East: What opposes this?
- Bulk Buying (cheaper per unit, creates waste)
- Weekly Meal Prep (assumes everything lasts 7 days)
- Two-Bin System (requires Reserve, which rots for perishables)
South: Where this leads
- Ice Cube Freeze (rescue for herbs)
- Eat Me First Bin (managing aging items)
West: What’s similar?
- Agile Development (respond to need vs plan everything)
- Fresh Fish Markets (no inventory, daily catch only)
