Is there any way to avoid missing milestones without micromanagement?

Looking back at my career, I find that understanding the reason why having this milestone done by this date is important really helped. Is it "according to our contract if we don't deliver all of this by this date, the client doesn't have to pay us anything and we'll have trouble making payroll" or "I pulled a random date out of my ass in a meeting 6 month ago, and I don't want to look bad in front of my boss by explaining that I got the time estimate wrong". In the first case we pulled out all the stops to make sure we hit the deadline, in the second case we worked at our normal pace and didn't care too much

Not all deadlines are created equal and if you have a lot of deadlines that feel random and meaningless with no consequence of missing them, then people will feel that and not take it seriously. Have deadlines that are relevant for the project, and explain the relevance of each deadline to the team, and you'll hopefully get better results.

This feels weird, when you ask them directly "Why did this milestone get missed, when it seemed on-track?", what are they telling you? Do they have other priorities and tasks from other managers? Else, what is going on? If you ask the other managers, what do they tell you? Are your team's priorities misaligned with your priorities? It feels like there are some basic conversations missing, or people aren't taking you seriously, or they have conflicting incentives.

Invisible work and unexpected blockers aren't issues of motivation unless you are seeking to get them to work overtime to overcome these blockers.

> even if the milestones are aligned by everyone.

Everyone agreeing on something doesn't mean that everything is understood or correct.

It seems that your estimates are based on everything going right.

If people miss milestones for valid reasons you are setting the wrong milestones. And then missing them undermines the credibility of the next ones. Get on top of your estimating.
