What they are saying here is that the component was designed to X, but, not manufactured to those specifications.
Depending on who made that actual component, this is either a failure of Boeing directly or a failure of Boeing to ensure that their suppliers have adequate processes in place to capture these kinds of problems.
This is actually a much more serious failure than a design failure because the problem can't easily be systemically addressed, there is no single component they need to address now. Boeing can not simply say "we checked the other engine mounts in production and they are fine". Even saying that they addressed the issue with the production of that component is insufficient. The real root cause here is why any component which did not meet design specifications was accepted and allowed to be installed on the aircraft. Boeing will need to do a huge review to understand this and may need to inspect and replace huge numbers of other, seemingly unrelated, components.
