There is hard block and soft block. Hard block means you have no clue how to continue and so of course you should get help right away. Soft block means you have ideas and are working on it, but - unknown to you - someone else on the team knows exactly how to solve that problem and could solve it for you in a few minutes or you can spend all weeks working out the answer. The soft block is a lot more common - engineers are smart people who can solve complex problems, but we often fail to use the help of someone else who has already solved it. Thus the standup should be able airing problems that you just need to finish typing the solution in. Sometimes someone else will say "I can help you do this faster", others it is just keep working until you get it.
However 99% of the time what I see in Real Life is even when it's just devs talking they aren't offering up enough information for either of those to happen. Either imposter syndrome kicks in and they don't want to look stupid in front of their peers, or they're just annoyed at having a meeting. So it just becomes a status update meeting anyways
This to a T. An awful lot of stuff coulda gotten crushed, quickly, if I'd just asked for help ASAP instead of siting on it and feeling dumb.
edit: to be clear, I think they're good definitions, just never heard a definition
BS "can I pick your mind", chit/chat, questions that could be Googled, and of course, micromanagement BS are interruptions.
DSUs themselves are also interruptions -- it's just that they're scheduled and not event-based.
In other words, necessary communication is not interruption. Accidental communication is interruption (to be read as the same concept as necessary and accidental complexity).
Sometimes stand-up for me means 'remind myself what I was doing'; if not that then I've certainly not got far past it, haven't had long to get much done or be stuck. I'm unlikely to say in a stand-up that I'm stuck on something, I'll have a(nother) crack at it and perhaps ask after lunch if necessary.
If in the course of one's work one becomes blocked, would one really wait until the following day's stand-up to tell anyone about this?
If so then I think both the worker and the company have bigger issues than whether the stand-up itself is a good use of time.
The mind boggles.
