Operations and Support Phase (Element of Defense Acquisition System)

The Operations and Support Phase seeks to execute a support program that meets materiel readiness and operational support performance requirements, and sustains the system in the most cost-effective manner over its total life cycle. AAC engineers help the PM planning for this phase, prior to program initiation, with development of the LCSP as part of the Acquisition Strategy. Entrance into this phase requires an approved CPD, a successful Full-Rate Production (FRP) Decision, and an approved LCSP.

AAC systems and logistics engineers provide important support to the PM during this phase’s two major components, Life-Cycle Sustainment and Disposal.

Life-Cycle Sustainment (planning)
• translates force provider capability and performance requirements into tailored product support to
achieve specified and evolving life-cycle product support availability, reliability, and affordability parameters.
• is considered during Materiel Solution Analysis and matures throughout Technology Development
• must be flexible and performance-oriented, reflect an evolutionary approach, and accommodate
modifications, upgrades, and reprocurement
• considers supply, maintenance, transportation, sustaining engineering, data management, configuration
management, HIS, environment, safety (including explosives safety), and occupational health, protection
of critical program information and anti-tamper provisions, supportability, and interoperability

Because a robust systems engineering methodology is paramount to the effective sustainment of systems, the PM must:
• Design the maintenance program (beginning at program initiation) to minimize total life-cycle cost
while achieving readiness and sustainability objectives
• Optimize operational readiness via human-factors engineering; diagnostics, prognostics, and health
management techniques; embedded training and testing; and serialized item management techniques
and automatic identification technology (AIT), radio-frequency identification, and iterative
technology refreshment.

AAC engineers help the PM work with the user to document performance and sustainment requirements in performance agreements that specify objective outcomes, measures, resource commitments, and stakeholder responsibilities. Support includes Performance-Based Life-Cycle Product Support (PBL) planning, development, implementation, and management. PBL is the current best strategic approach for delivering required life cycle readiness, reliability, and ownership costs.

DoD Components must initiate system modifications, as necessary, to improve performance and reduce ownership costs. AAC engineers help the PM to conduct continuing reviews of sustainment strategies in order to compare performance expectation to actual performance results. PMs must continuously identify deficiencies in these strategies, and adjust the LCSP as necessary to meet performance requirements.

The Future – Sense & Respond Logistics (S&RL)

While PBL is the current best approach for managing life cycle readiness, reliability, and ownership costs; Sense & Respond Logistics (S&RL) is in the future. S&RL is accomplished by through the use of Condition-based Maintenance (CBM). CBM is a set of maintenance processes and capabilities derived from real-time assessment of weapon system condition obtained from numerous technologies including embedded sensors and external measurements using portable equipment. CBM will allow a unit to be maintained only upon evidence of need. For example, a vehicle’s routine maintenance schedule would evolve based on the conditions under which the vehicle was actually driven, even considering actual traumatic events the vehicle suffers, actually measured rather than estimated.

At the end of its useful life, the system must be demilitarized and disposed of in accordance with all legal and regulatory requirements and policy relating to safety, security, and the environment. During the design process, PMs must document hazardous materials contained in the system in the Programmatic Environment, Safety, and Occupational Health Evaluation (PESHE) and must estimate and plan for the system’s demilitarization and safe disposal.
