We don't need to tidy up: everything we do is inside a computer.
This worried me for some time, but I only recently realised exactly what the problem is with this: 5S is not about tidying up, it is about minimising waste.
In relation to the manufacture of auto-mobiles, Taichi Ohno identified seven wastes:
- Unnecessary transport
- Excessive motion
There have been additionally proposed fundamental wastes in businesses, most notably:
- Goods that don't meet user demand
- Unused human potential
In software development, only some of the physical wastes at first seem to apply, but I suggest that almost ALL of the wastes apply to software development. Just think about it.
