Logistics, Sustainment and Product Life Cycle Support
We provide the full spectrum of logistics support to Program Offices and Naval Warfare Centers to ensure Sustainment and Supportability of DoD Weapons Systems and Platforms.
Total Life Cycle Systems Management (TLCSM)
According to the Defense Acquisition University, sustainment involves the supportability of fielded systems and their subsequent life cycle product support. The ultimate measure of a successful and affordable sustainment strategy is the application of that strategy after the system has been deployed for operational use. PURVIS embraces Total Life Cycle Systems Management (TLCSM), as an overarching approach to DOD projects, that enables that objective.
PURVIS contributes to our clients’ TLCSM success through the integrated execution of logistics support activities, as illustrated in this figure.Read more
During systems engineering requirements definition, PURVIS’ product support process is key to the identification and assessment of the supportability, and affordability, of design alternatives. Product support requirements (Key Performance Parameters, Key System Attributes, and supportability metrics) are derived from Operational Requirements Documents, Capability Design Documents, and associated system specifications.
Product Support strategies are developed and supportability analyses conducted to evaluate the evolving system designs. These analyses include Reliability Centered Maintenance, Maintenance Task Analysis, and Level of Repair Analysis. We use the results of these as the basis for the development of product sustainment strategies in program documents such as Life Cycle Sustainment Plans, Maintenance Plans, and Navy Training System Plans. We have also successfully conducted Core Depot Source of Repair analyses, conduct Performance Based Logistics Assessments, and assist with the execution of Independent Logistics Assessments and Supportability Reviews.
Integrated Product Support
During product development, PURVIS develops the requisite logistics products including training, Operation and Maintenance Interactive Electronic Technical Manuals, support equipment, and the provisioning of spare and repair parts, which are developed in parallel and validated against the original sustainment strategy. Our activities in support of that sustainment strategy include:
Coordination of logistics information technology and other enterprise integration efforts
Implementation of logistics footprint reduction strategies
Identification and evaluation of technology insertion opportunities
Management and coordination of configuration changes resulting from technology improvements and changes in requirements
