> I mean, think about the software you use. Of all the shops that produce that software, which ones do you trust more than others? I'd be willing to be it's the ones that delivery predictably. At the very least the ones that deliver updates reliably - as in they do what they say.

Of the software I use (slack, cloud infra, vim, Jira) exactly none of them tell me precisely when a feature will be delivered. They work hard on it and release it when it's ready.

A deadline like "in a few weeks" is acceptable. A deadline like "in 17 days" is asking to be missed.
