The existing org chart is the biggest barrier to AI productivity improvements, because tasks/responsibilities and departmental boundaries are set up for the old way to get things done. This is why adding AI to an existing org chart results in modest (at best) improvement. Starting over with a new org chart is the fastest path to higher productivity, but it should also work to gradually migrate to a more efficient structure by not hiring. Of course this could take many years and meanwhile you'll be outperformed by a smaller org.
