WORK BREAKDOWN STRUCTURES FOR DEFENSE MATERIEL …

1 MIL-STD-881D 9 April 2018 superseding MIL-STD-881C 3 October 2011 DEPARTMENT OF DEFENSE STANDARD PRACTICE WORK BREAKDOWN STRUCTURES FOR DEFENSE MATERIEL ITEMS AMSC 9915 AREA MISC NOT MEASUREMENT SENSITIVE MIL-STD-881D (THIS PAGE LEFT INTENTIONALLY BLANK) MIL-STD-881D iii FOREWORD 1. This Standard is approved for use by all Departments and Agencies of the Department of DEFENSE (DoD). It is for direction and should be included as a contract requirement. 2. This Standard addresses mandatory procedures for all programs subject to DoD Instruction 3. This military standard is applicable to all DEFENSE MATERIEL items (or major modifications) (a) established as an integral program element of the Future Years DEFENSE Program (FYDP), or (b) otherwise designated by the DoD Component or the Under Secretary of DEFENSE (Acquisition).

2 This Standard is mandatory for all Acquisition Category (ACAT) programs. This revision has resulted in many changes being incorporated into MIL-STD-881D, but the most significant ones include the following: a. Appendix A - Aircraft Systems and Appendix H - Unmanned Aircraft Systems have been merged into a new Appendix A - Aircraft Systems, since unmanned aircraft are considered Aircraft Systems. b. Appendix C Missile Systems and Appendix D Ordnance Systems have been merged into a new Appendix C Missile/Ordnance Systems which focuses on tactical missiles and munitions due to their commonality in structure and intent. c. Appendix D is now Strategic Missiles Systems which focuses on Intercontinental Ballistic Missiles (ICBM) and strategic missiles used by Missile DEFENSE Agency.

3 Previously strategic missiles were part of Appendix C Missiles Systems. d. New and revised definitions have been incorporated into Appendix F Space Systems to improve clarity and understanding of application. e. Changed the title of Appendix G from Surface Vehicle Systems to Ground Vehicle Systems to reflect the common terminology for land and amphibious systems. f. Changed the WBS in Appendix G Ground Vehicle Systems to reflect the approach to buying family of systems vehicles ( , variants). g. Changed the title of Automated Information Systems (now Appendix J) to Information Systems/ DEFENSE Business Systems to reflect DoDI : Business Systems Requirements and Acquisition.

4 H. Added a Sustainment Structure for Information Systems/ DEFENSE Business Systems (Appendix J) to recognize the overlap of acquisition and sustainment activities on the acquisition contract. For IS/DBS, this structure MIL-STD-881D iv should be used to appropriately reflect sustainment activities on IS/DBS programs. i. Added and defined in the Common Elements Appendix (Appendix K) required reporting elements under Systems Engineering, Program Management, and System Test and Evaluation related to Integrated Logistics Support, Software Engineering and Management, and Cybersecurity. j. Required Rate Tooling to be separately identified within Integration, Assembly, Test, and Checkout at the appropriate level.

5 K. Further defined Peculiar Support Equipment and Common Support Equipment (Appendix K) to a lower level which identifies the subassembly the equipment supports, ( , Airframe/Hull/Vehicle, etc.). l. Added Contractor Logistics Support (CLS) (Appendix K) to reflect that contractor sustainment support may be completed at the depot during the acquisition phase. m. Added Data Rights under Data (Appendix K) to reflect the Government purchase of contractor data rights. n. Included the Cost Assessment Program Evaluation (CAPE) Sustainment Cost Reporting Structure (CRS) (Appendix L) to provide a description of the transition between the Work BREAKDOWN Structure (WBS) to the CRS during a program.

6 4. A Work BREAKDOWN Structure (WBS) provides a consistent and visible framework for DEFENSE MATERIEL items and contracts within a program. This Standard offers uniformity in definition and consistency of approach for developing all levels of the WBS. Generating and applying uniform work BREAKDOWN STRUCTURES improves communication in the acquisition process. It also provides direction to industry in extending contract work BREAKDOWN STRUCTURES . 5. This Standard supersedes MIL-STD-881C, dated 3 October 2011, titled Work BREAKDOWN STRUCTURES for DEFENSE MATERIEL Items. MIL-STD-881D is based on the cooperative efforts of the military services with assistance from industrial associations.

7 Changes to the Standard specifically address advances in technology and modifications of the acquisition process, and incorporates new MATERIEL items, development concepts, and approaches. 6.
