Maybe for MSFT, but that is not how it was where it came from.
The Milestones were where bonuses were paid, or contracts were fulfilled.
At X date, the Milestone deliverable was due..if they hit it...they got
their money..if they did not...they either defaulted on the contract, or
just lost a bonus.
Yes, I know this for a fact, I was a product manager on a few projects with
milestones and attached bonus'.
If what you say is true..then I have no idea how anyone ever knows what is
happening.
As I mentioned in my earlier post, different companies have changed thier
naming conventions to suit their changing purposes.
