The DARS will be numbered in accordance with the method prescribed in DFARS Subpart 201.3 Agency Acquisition Regulations.

(a)(ii) To the extent practical all DARS text (whether implemental or supplemental) will be numbered as if it were implemented in accordance with DFARS Subpart 201.303-Publication and Codification. Supplemental numbering will only be used when the text cannot be integrated intelligibly with its FAR or DFARS counterpart. DARS supplements shall parallel the FAR and/or DFARS, with the exception that supplemental sections are numbered using 90 or (S-90). Parts, subparts, sections, or subsections are supplemented by the addition of a number of 90 and up. Lower divisions are supplemented by the addition of a number of (S-90).

(D) The table shown in DFARS Subpart 201.303(D), DFARS Numbering provides an example of the numbering system. Sample Table with DARS Numbering below.

Table 1-2 DARS Numbering

(S-90) Sections under subparts will be enumerated using FAR or DFAR numbering conventions, depending on whether the FAR or DFAR is being implemented or supplemented.

(S-91) DISA PS21 shall review all DISA acquisition-related procedures (both mandatory and non-mandatory) that impact the Agency prior to implementation. The procedures are generally implemented as DISA Acquisition Templates, Samples, Guides, and Deskbooks and referenced in the appropriate part in the DARS. DISA PS21 facilitates implementation of all DISA Acquisition Documents. DISA procurement and acquisition policy and guidance can be found at https://www.ditco.disa.mil/Hq/AqInfo.
