A sales driven organizational model works well if you sell products that don't have any requirement for post-sales support. There's no service department or requirement for such if your business is toilet paper. Or any consumable, disposable, or low cost, throwaway item. If Motorola didn't make a radio costing more than a hundred dollars the service requirement would be zero. But obviously, durable and valuable goods that would be considered by the customer to be worth fixing, for a reasonable time after puchase, are a different story.
Just looking at the current radio offerings by both Motorola and Harris, and their service documentation, it's abundantly clear that they are trying to minimize the service side of the business, and doing it by essentially saying "This stuff is high density surface mounted component technology, all shielded, requiring expensive specialized tools and very specialized training so we don't support component level repairs" and in truth they're right about that. While it's not impossible to work on these current generation devices at the component level, it takes FAR more than your trusty Weller WTCPN solder station that served you well in the 80s and 90s!
On the software side, even the current Harris XL generation radios literally don't have a computer-based alignment procedure, at least not one that's accessible to the usual field technical staff. The adjustments that can be made are made within the standard RPM software, after you create a test personality that you load into the radio. And then, you have very limited control, over RF power output, and you can adjust the reference oscillator within the radio's own software itself, but beyond that point, you're limited to performance tests. If the radio fails the performance tests, it gets shipped back to Harris, and they presumably have alignment software and tools that are never seen by the local service center's technicians.
Service is a COST, not a revenue center, so you can expect that the manufacturers will try to engineer the ability to service their gear out of the product line as much as is possible.
