ECN numbering
ECN numbering
(OP)
I need some info regarding how others number their change orders. My experience in the industry has been to use non-significant ECN numbers, allowing for changes to multiple drawings with one ECN, but at my current employer the drawing number is used followed by the ECN number, 123456ECN-001 for example. This has worked well while they were a small company, but they are rapidly growing and this system does not allow for multiple file changes under one ECN. A minor part change affects several tools and assemblies, and as it now stands, they each need their own ECN to effect the change.
In todays electronic environment, I have a hard time accepting that "they need to be tied together" with the same number as a valid argument.
Other experiences would be greatly appreciated, especially within the aerospace industry.

RE: ECN numbering
Current employer, date (YYMMDD) initials and then a numeric for if it's the first, second... eco that day. So my first ECO today would be 081201-KAT-01. So again non significant, although every 10 years a number could repeat itself.
Your places way, with the drawing number in the ECO number sounds like a pain.
KENAT,
