they do both actually.. maybe I could say that the service we provide are more like how we package the maintainance contract around the equipment that we may or may not provide to the customer. customization of maintenance service maybe? may include spare parts and consumables depending on the agreements
Isaiah,
If the customer specifies the maintenance work and spare parts then the customer retains responsibility for the design of this service.
If the customer specifies equipment availability objectives then you are responsible for the design of your maintenance service to fulfill those objectives.
You may also design your predictive maintenance services where you recommend vibration, temperature, oil analysis and other predictive measures and then issue reports based on your analysis of the results. Indeed, these reports may then drive the design of the maintenance you provide.
Advising your customers which pre-packaged maintenance service to invest in is also your design. Customers who do not take your advice retain responsibility for design.
Best wishes,
John
