When I was young, I heard it many times, and couldn't make anything from it.
What's the audience exactly? How do I know them? Once I know them, what am I suppose to do? And all that stuff is contextual, so what are we talking about really?
When learning to negociate, knowing your audience is a very different thing than when trying to teach. Very few people are able to pull it off accross fields.
So I decided to write an article that targets a specific case with a concrete application and examples.
This would have been more useful to me back then.
I try to keep the details to the lowest denominator, which usually means mentioning what the problem is and what the proposed solution is in few lines. But eventually someone will ask for more details, and then the conversation veers off to technical discussion that I am sure the PMs and Analysts don't understand.
and if this is a demo, then it should only really require stakeholders.
if the meeting is for product to share their vision or requirements, save the tech talk for later
its very tempting to get into the weeds of things, but this can be "parking lotted" as the kids say
