2. Release Stages:
How many stages (phases) of release do you have? Ave 3.06

What do you call them? (The most common answers are as follows)
1 Design / experimental / Development / Proto
2 Prerelease / Proto / Pilot
3 Production
How do you tell (on the drawing) that a document / part is "ready for" a particular stage? (example: Rev blank = development, rev numeric = pilot, rev alpha = production):
Can tell each / all stages by looking at the drawing = 10
Can tell some but not all by looking at the drawing = 5
Can't tell any = 1
How do you tell (on a BOM) ?
(example: Status code 1 = Development, 2 = Pilot, 3 = Production):
Can tell each / all stages by looking at the BOM = 7
Can tell some but not all by looking at the BOM = 7 (4 don't input to the BOM / MRP until production)
Can't tell any = 2

3. BOMs
Is the parts list; on the assembly drawing? 9 Yes - 7 No
on a separate controlled document? 15 Yes - 1 No
both? 8
How many manual or computer data bases of the parts lists are maintained in the company? (example; Engr CAD, MRP plant 1 and 3, MRP plant 2, Publications = 4 ) Ave 2.3
Plan to reduce / attain one BOM database? 8 Yes - 3 No
already have only one database! 5
4. Supplier Items
Are supplier items part number differently than other items? 2 Yes - 14 No
Do you have a separate part number for each supplier you buy the same part from?
2 Yes - 14 No
Do you use a SCD (Spec Control Drawing or Source Control Drawing) to buy a given part from more than one Supplier? 14 Yes - 2 No
(Some didn't recognize acronym "SCD")
Do you identify the supplier on the part drawing / SCD? 5 Yes - 11 No
Do you maintain an AVL (Approved Vendor List)? 13 Yes - 3 No
Do you create drawings for solvents, glue, solder, etc.? 5 Yes - 11 No

5. Deviation (and other similar) forms:
Have this process? What form(s) do you use? 16 Yes Mostly called "Deviation"
Are these forms sometimes used to make design changes? 7 Yes - 9 No
Almost always followed by formal DCN.
How many & who signs? Ave 4.07 Almost always include QA, Mfg & Engr.
Where are they filed? 7 CM / Doc Control - 9 other places (Quality, Plant, etc.)

6. Forms:
Some companies use separate form / process to release, request changes, and to specify changes and to implement changes. Ave 1.67 (one on line with multiple screens)
What forms do you (and your plants) use?
Many combinations used - 8 have only one form to do all - 2 do not use a form to release (drawing notations suffice for them)
If you use a separate form to release:
Can a change requiring a new part have that part released in the change, 11 Yes - 1 No or do you first have the part released by that form / process and then "picked up" in the change form / process? 1 Yes - 11 No

7. Change Process:
If we generally describe the change process as having the following major events:
Responsible Engineer Recognize Problem / challenge Redesign Complete
Change Control Board / "signers" approval
CAD / Hand-drawn Master Drawings / Docs Updated (change incorporated in docs) / MRP Updated
Change Incorporated in Product (excluded on "document only" changes)
Does CM / EDC play a roll in the redesign (Recognize Problem to Redesign Complete)?
7 Yes - 9 No Note slight difference than question #1 "define change with the engineer?"
Is Redesign Complete defined by
Marked up documents "attached" to DCN? 15 Yes - 1 No (might be hand marked, CAD overlays / redlines, or word document mark ups)
From-To detailed description in the DCN? 13 Yes - 3 No
Flag Notes on the drawing? 9 Yes - 7 No
Detailed description in the Drawing Revision Block? 2 Yes - 14 No
Note word "detailed".
Where in the process are approvals obtained ? Most later - at Team CCB meeting.
Are the changes incorporated into the masters before or after approval? 5 before - 11 after
Is the responsible engineer required to sign the master after incorporation 7 Yes - 9 No
Where in the process is the impact of the change identified? 8 early - 8 later at CCB, etc
Do you have a team / board that reviews / approves changes 13 Yes - 3 No
Where in the process does the team / board first see a change? 8 early - 8 later
How many people approve / sign the typical change? Ave 5.6
What functions do signers represent? Usually Engr, Mfg, Materials, Quality, CM and others
Must the MRP be updated before the Drawings are updated? 1 Yes - 15 No > 2 Neither
Must the Drawings be updated before the MRP is updated 13 Yes - 3 No
Does Manufacturing proceed to implement the change from the approved DCN (mark ups or whatever), 8 Yes - 8 No or must they have the updated documents before proceeding?
An ADCN process would allow several changes (by mark up or "from-to") to the same document to be queued-up and incorporated after a limit (typically 5) has been reached.
Do you use this feature? 5 Yes - 11 No
Do your internal customers like this feature? 3 Yes - 2 No
(One yes marks up a "master" with all queued changes)
Does CM / EDC get feedback from Manufacturing as to the actual effectivity of any changes? 5 Yes - 11 No (5 nos keep actual in plant / mfg)
If yes, which changes? Any product change.
Do you generally limit one change to a "fix" for one problem / challenge? 6 Yes - 10 No
Do you measure the volume of changes done per week? 11 Yes - 5 No
How many / wk? Ave 47.9 (for those answering "Yes")
Do you measure (change by change) the thru-put time of changes? 7 Yes - 9 No
If yes, describe those measurements and results in the above terminology and be precise (example: The time from Design Complete to Update of the MRP and Update of the Master documents, which ever is later, averages seven work days): Highly variable answers for the 7 "yes". Range as follows:
5 work days thru CM (From Engr complete to Docs and MRP updated)
45 work days recognition of problem to Docs and MRP updated.
