Conceptually, my clients and I find it helpful to think of meeting projects not as the home for a task, but as a transient multi-home location only.
Particularly for recurring meetings (weekly staff meetings, monthly board meetings, etc.), projects where each meeting occurrence is its own task are a great solution, and there are many ways to organize such projects. (I have one comprehensive solution that can be simplified easily that I offer my consulting clients.)
Regardless of the particular approach, the overriding concept that can be helpful to bear in mind is that tasks more permanently belong to another project, be it the event planning project, the team’s work stream project, a 1:1 project, etc. Temporarily, it’s a topic of interest in a meeting, perhaps across a few meeting occurrences, but it’s primary residence is elsewhere.
Ducking for incoming disagreements,
