As a bona-fide, certified, rarified SCRUM-MASTER here (respect mah authoritay), I just have to say - does anyone really think a standup is a 'collaborative' meeting? It's a check-in meeting! If you weren't productive yesterday, just say so - as long as you are generally keeping your commitments and shipping your features on time, it's fine. If you are behind, you can verbalize it - and if it makes sense, it makes sen…
A check-in meeting is still a collaboration tool (the phrase I used), so... yes? But I get the sense you're using these words differently from their normal meaning, so it's possible that in some jargon-sense they're not, because a check-in meeting can't be a collaboration tool because those have strictly exclusionary definitions, or something. But under ordinary usage of the terms, yes, sure, a check-in meeting's pro…
I see what you are saying though, I think my definition of 'collaboration' didn't immediately translate into your head. When I think of check-in, I just think of taking attendance. Who is at work today? In two or three sentences, what are you working on today? This way, the PM knows who has a little bit more slack in their day, and who can be assigned to triage a bug that pops out of nowhere, for example. I work at a smaller company, where product engineering goes hand in hand with fixing bugs. They aren't different teams.
'Collaboration' implies some sort of positive activity, that creates or generates something, whereas I think of a standup as simple a check-in exercise that provides a mechanism for people to notify someone 'hey, I need to discuss this with you, let's stay on after the call'.
My definitions are my own though, and probably pretty weird. I've tried to internalize the spirit of Agile, and through that internalization my main conclusion with a standup is that it's just a way to check in, and springboard into deeper triage conversations while allowing product management to understand what is being worked on.
