Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities.

All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://apps.mlca.uscg.mil/vdiv/surveys/Post_availability/ http://apps.mlca.uscg.mil/vdiv/surveys/Post_availability/

If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:
