This is how companies plateau and become stagnant. The issues described do not spur action (e.g. "these two just need to collaborate better"), they fester, and eventually, a non-trivial number of internal teams are "captured." They won't burn the company down, the under-performing individual is not likely to do anything to warrant actually being moved/fired, and so, the status quo remains...and spreads.
And then we wonder why large companies simply cannot innovate or execute on broader change initiatives?
