The Two-Bin Kanban: Never Run Out of Consumables Again
How much time does your team waste chasing consumables? Gloves. Screws. Pens. Drill bits. Tape. Small stuff. But the frustration is massive.
A coastal engineering business in Tasmania solved this with a dead-simple system: two-bin Kanban.
How It Works
- Every consumable has two bins
- When the front bin empties, you pull it out
- Behind it is a second bin with more stock AND a card
- The card goes to the "on order" board
- Once a week, the apprentice walks the boards, collects the cards, fills out a tick sheet, and places the order
- When stock arrives, cards come off the board, product goes back in the bins
5+ Years Running
That's it. Running for over five years. No more chasing. No more "who used the last drill bit and didn't tell anyone."
The discipline: when you see a card, it goes on the board. No exceptions.
Set It Up This Week
You could set this up on your building site with containers, labels, and a whiteboard. Apprentice does the run every Friday. How much time would that save you?
