Multiple
Filler Metals
Special
Exceptions
Subtle
Differences
Multiple
Joint Designs
Make POT More Specific
One filler = limited joint designs = minimal notes / exceptions
One Technique in Legacy Procedure = 3 or 4 or 5 in POT (dbase – who cares?)

Advantages
Creating PQR / WPS
Once PQR created - Print Qualified

HUNTINGTON INGALLS INDUSTRIES PRIVATE/PROPRIETARY LEVEL I
Advantages
Creating PQR / WPS
Enables and Disables Fields Based on Inputs
***If you select
ceramic backing
you have to
enter
manufacturer
and type***

HUNTINGTON INGALLS INDUSTRIES PRIVATE/PROPRIETARY LEVEL I
Advantages
Creating PQR / WPS
Bounces input against the spec and flags incomplete info
***Missing Minimum Travel Speed***

HUNTINGTON INGALLS INDUSTRIES PRIVATE/PROPRIETARY LEVEL I
Advantages
Creating PQR / WPS
Prompts user where to go in spec for rule
15
HUNTINGTON INGALLS INDUSTRIES PRIVATE/PROPRIETARY LEVEL I
Advantages
Real Time Revisions
Old System: Make change in MS Word + send to QA + QA send
to repro + QA make distribution + recipients make changes to
paper copy = Weeks
NAVWELD System: Make Change in Dbase + Validate
electronically + Revised Procedure ready for use = Minutes
Caution
Real Time Revision = Double Edged Sword
Person looks at procedure – we make
change afterwards – he is using an
outdated procedure.
Solution:
Adding something no big deal – anytime
Taking something away – we need to take the action to let user know.

Challenges
ABC
Computer Literacy – What about those who aren’t
proficient with computers?
- Ease of Use
- Training
Reliability - What happens if the computer crashes?
- Back-Up Paper Copy
- Back-Up PDF Copy
22
Resistance to Change – Why can’t you leave the
procedures the way they’ve always been?
- Involve users in the process
- Stress the advantages
- Listen
- Tenacity
