When submitting a justification for Navy Senior Procurement Executive approval, use of the Annex 1 standard Navy Secretariat format for the forwarding memo is encouraged; however, it is not mandatory and activities may use their own standard formats. If activities use their own format, they must ensure that the arrangement and content of the paragraphs follow the structure and content used in the Annex 1 template. Memoranda should be brief and concise. Attached charts or graphs may also be used to convey required information. The forwarding memo should be submitted electronically as a Word file in the event that any minor revisions, agreed to by the contracting officer, may be made by DASN(A&LM). Any signed or initialed page of the forwarding memo should also be submitted as a .pdf file.
