@patigallardo.bsky.social Saw your explanation further in the thread (did not load fully when first seeing your post). The effective lack of ownership (via sufficient expertise, etc) is a tripping point when working with external entities or even across segments/divisions of the same biz entity.

Acceptance testing is usually delayed to be useful and hence quite likely to surface a mismatch in the expectations of the system. Would like to understand other reasons for it being problematic.
