I’m trying to read a bit more around processes and optimising output and reducing waste. I found it hard to remember the seven types of waste, so drew a diagram to make it easier.
I discovered that I found it easier to remember these by imagining a factory workfloor such a fruit packaging factory, where things can spoil so inventory stockpiling is a bigger priority. I think about the inputs, what happens during processing, and outputs - and where time could be wasted.
The original seven types of waste:
- Not enough inventory (waiting)
- Too much inventory
- Unnecessary movement
- Inappropriate processing
- Overproduction (outputs are stockpiled and not used)
There is now an eigth type of waste:
- Underutilisation of humans
