Active work gets prime space
The desktop should support current tasks rather than every project.
Reference differs from archive
Frequently consulted material needs easier access.
Create one inbox
Unprocessed paper and items need a defined intake point.
Keep devices serviceable
Cables and electronics need accessible, ventilated placement appropriate to the product.
Practical boundary. Measure first, respect product load limits, and do not improvise wall, ceiling or overhead installations when the structure or appropriate hardware is uncertain.
