Do you experience a similar situation at your job? If so, how would you like to improve it?
Publishing agenda before meeting is a must. There is no point in starting a meeting on a blank note.
Many meetings can just be conducted over threads on slack or Microsoft team. What I mean by this is, the type of meeting where you want to confirm or come to an agreement over something, that chat thread can help flush out details before you waste everyones time over it.
In short, move most of your meeting and emails to your collaboration tool.
Even old-fashioned collaboration tools like e-mail can be used effectively to avoid meetings. A discussion of an issue that doesn't need to be decided immediately can just as easily be done asynchronously via e-mail.
I've gotten countless meeting requests that are just some product manager wanting to get a specific item of information from a group of developers. I've averted many of these meetings just by declining the meeting request with "Here's the information you need, no need to have a meeting about this. E-mail me if you need more information."
Bad meeting: Sue: "Could you get me the figures for bugs-over-time?" Bob: "I'll have to get back to you on that."
Good meeting: Sue: "Bob investigate our bugs-over-time metric. Can you share with us what you found out?"
If you are asking a question in a meeting that could have been asked before the meeting just as easily, you're wasting expensive "meeting time".
