When a meeting doesn’t result in a decision it means there wasn’t enough preparation conducted by one or more parties.
That’s not always bad, sometimes its better to have two short meetings instead of one overwrought session.
But if multiple people are gonna spend their time knocking their heads on a subject, it should come up with some results.
At the very least, we should come out with a clear goal for what needs to be studied before the next meeting and a gameplan for getting to a resolution.
