Over-collaboration and under-collaboration have their downsides.
When you under-collaborate in your business, information and ideas are not shared with others. Lone wolves may work well in some situation but those are the exception.
But over-collaboration can lead to conflict or decreased productivity.
To have a constructive collaboration, you need to establish a compelling "why" for every proposed collaboration. If there's no why nor purpose to the meeting, walk away.
A unifying goal will let everyone in the team determine how much collaboration is needed. To set effective goals, they must be common ,concrete, measurable, and finite.
