Now wait a minute, I'm a retired engineer. Of course I thought of future maintenance needs since I grew up on a farm, and do most of my simple home and auto repairs. Does make you think though that they don't include a mechanic during the design process.
In my last capacity I managed the serviceability process for my company. When developing a new product (model) my team worked closely with engineering to develop service repair and diagnostic strategies to ensure as low a repair time as possible. Since each technician in the field had a standardized set of tools issued to them, engineering was compelled to ensure the design was field compatible (tools, training, logistics).
If engineering wanted or was forced to a design that did not meet field requirements, engineering was required to absorb the cost of any new tools for the field and fund the field staff for any extra service time.
This almost always prevented unusual field service issues. I happen to know that this process is alive and well at the auto manufacturers.
