I often deal with colleagues (who are not in working in the same place), who promise to deal with some task (they have to fix something, install something, etc), but the promised deadline comes and goes, and I do not hear back.
Tuesday: "I will fix this issue and deploy a new version by the end of the day."
Wednesday 9am: No new version deployed (and an important work I need to work on is blocked).
When and how should I ask for an update? How long to wait? In what time intervals to ask? When to talk to my boss that I am blocked (and I do not want to do that twice each day)?
In the example, should I ask right in the morning? Every hour? What is the right way to deal with that?
