The moment
There was a gap between two tools. Work came out of one and had to get into the other, and every week somebody moved it across by hand. So you bought a third tool to close the gap. It demoed well. Its site described your situation almost word for word.
Six weeks later you have three tools and the same gap. The handoff still happens on a Thursday afternoon, still by hand. What changed is that there is now one more login, one more invoice, and one more thing to explain to whoever joins next.
The turn
The obvious fix is one more integration. A sync job, a connector, one small step that makes the new tool talk to the old ones. It is the fix everyone reaches for, because it is the one that can be bought this week and shown on Friday.
But an integration is a promise two vendors made to each other, and neither of them has to keep it. One ships a change and the promise quietly stops being true. Nothing announces that. The gap does not close, it moves down a layer, into a configuration that exactly one person understands. That person is now the integration. The same amount of work is still being done. It is just harder to see, and it fails in a place nobody is watching.
What moved it
We stopped adding tools and asked a smaller question: who owns the handoff between the two tools that already existed. Not which system owns it. Which person.
The question was uncomfortable, because the honest answer was nobody, and that is precisely why it kept getting solved by purchase. Once a person owned it, the gap became a five minute conversation instead of a standing sync job. An owned handoff has someone to decide when the shape of it changes, so it stops needing a system to hold it together.
The shift
Same two tools. No third one. The gap closed because someone owned it, not because something connected it.
That is worth saying plainly, because the next gap will look exactly like this one, and it will arrive with a vendor attached.
