Maintenance information becomes more useful when it is organized around the equipment rather than scattered across unrelated modules.
The machine is the context
Open an asset and the system should make it easy to see current work, maintenance history, preventive maintenance, technical documentation and related parts. That reduces navigation and helps the user understand what is happening around the equipment.
Useful context is operational, not decorative
A machine page should answer practical questions: What is open? What is due? What happened before? Which documents belong here? Which parts are related to this asset?
Mobile access changes the value of asset data
QR codes and mobile access can shorten the distance between the physical machine and its digital record. The point is not the QR code itself; it is getting the technician to the right maintenance context quickly.
