EMD

Engineering and Manufacturing Development

What it actually means

The acquisition phase between Milestone B and Milestone C where the system is fully designed, prototyped, qualified, and readied for production — historically where cost and schedule overruns concentrate, because it's where paper designs meet physics. "Entering EMD" is shorthand for a program getting serious.

Where you'll meet it
