My team has 15min standups, in holiday times we regularly stop after 10min. Very focussed on the sprint goal and getting each other unstuck- it's great. Much better than the "let's walk over every issue on the jira board and argue about technical implementations".
The first standup experience of my career predates “agile” and was run by my first engineering manager, who happened to be an ex-marine. QA was unhappy with the product. (There was QA!) 10m standups were instituted at 8:45a in the QA workspace. Great process hacking: QA could interject and also hear first hand orientation. Everyone started their day knowing the plan. (And everyone started their day at the same time.) Fun to reflect on how much has changed.
This is the thing I dislike most about chat. It encourage people to be lazy. Don't make any effort, just throw your problem out to the group the moment you don't immediately know what to do next.
This is generally how my team works, but we don't have a hard cap on the time. I just think nobody wants to debate about technical implementations early in the morning.
