One of the good things about a holiday is it gives one time to reflect, and surrounded by the excesses of Christmas the question of waste came to mind:
In a work context the seven wastes* are:
1. Overproduction - too much, too early or worse still both.
2. Waiting - a tea break at a downstream process caused by poor service from an upstream process.
3. Transport - unnecessary movement of Work In Progress.
4. Extra Processing - Fixing or doing it all over again.
5. Inventory - Excess raw materials, WIP and finished goods.
6. Motion - The extra steps and time taken by operators to do what they need to do.
7. Defects - Products or services that don't conform to specification or expectation.
Easy, but I wonder how many organisations consider waste beyond that which appears in the bin.
*Toyota's Chief Engineer Taiichi Ohno first articulated the seven wastes. The elimination of waste (muda) is at the core of the Toyota Production System (TPS).
