EBME dead? No, just evolving!
Providing you use original OEM sourced parts and fit them in accordance with the manufacturers instructions then nothing is stopping you making repairs.
The role of the EBME departments is evolving due to changes in technology. Whereas in the past it was simple to repair down to component level now it is becoming impossible. Embrace the change to the new environment! The new role is to be the technology gateway and manage the service rather than actually making repairs. As automation and robots rise we will all need to adapt.
Remember, you are also extracting money from public bodies, so should not blame others for what you are also doing! Working in partnership with manufacturers can actually bring about savings, and not be just about gouging public bodies for more money. Embrace the change.
