Of course, some interruptions like lunch or the end of the day are unavoidable. Phone calls and texts? Don't let your developers do them. > To single out 'standup' as a particularly disruptive interruption may be exaggeration. It isn't an exaggeration, because a standup is also a pending appointment and a mini-presentation. A lot of developer types actually get stressed out about this, no matter how small. Similar thing with responding to an e-mail. It's insane how much time some people spend on just a one line reply. Just minimize these things, don't make them part of your routine for routine's sake.
