Military Handbook- Review and Acceptance of Engineering Drawing Packages (1991)

4. General Requirements

4.1 EDP.
If not already in existence, some form of engineering drawing will be prepared by the manufacturer or system developer at the start of a program. During the concept/exploration and demonstration/validation stages of system development, the drawing package may contain only enough detail to permit design evaluations and cost projections. As the design progresses and the program moves through full scale engineering development and finally into production, the drawings become more and more detailed. The types of drawings described in MIL-T-31OOO enable the EDP to follow this progression
from design concept to production. They are:

a. Conceptual design drawings and associated lists.
b. Developmental design drawings and associated lists.
c* Product drawings and associated lists.

4.2 Reviewinq the EDP.
From its inception to its disposal, the EDP is a dynamic set of documents. As a program progresses, design changes are made? manufacturing difficulties are encountered, technology changes, and drawing errors are located. All of these events require the design activity to change the EDP. Regardless of the reason for changes, the EDP must be continuously reviewed to ensure that it accurately depicts the article in its current configuration.

4.3 Principal phases of EDP reviews.
The principal phases of the review process for EDP’s are:
a. Selection of reviewing activity and review of contract requirements.
b. Contractor indoctrination.
c, Technical reviews.
d. Documenting contractually deficient engineering data.
e. Final review.
f. Recommending acceptance or rejection of the EDP.
