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.

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:

Performance Based Initiatives

Assessment, execution and oversight of performance based logistics initiatives, including management of performance agreements with clients and support providers 

Manage Implementation

Oversight of implementation of support systems integration strategies 

Smart Maintenance

Application of diagnostics, prognostics, and other condition based maintenance techniques 


Coordination of logistics information technology and other enterprise integration efforts

Implementation of logistics footprint reduction strategies 

Technology Change Management

Identification and evaluation of technology insertion opportunities

Management and coordination of configuration changes resulting from technology improvements and changes in requirements 

Cost Management

Identification of opportunities for reduction in operations and support costs and monitoring of key support metrics 

Full Life Cycle Support

PURVIS also supports customers’ needs throughout the full life cycle of their products. We support the introduction of technology improvements through the development of System Change Documents within the Navy’s NDE-NM (NAVSEA Data Environment – Navy Modernization) process, facilitate Distance Support programs via Navy 311, develop training programs for system users, and administer robust configuration management programs for both hardware and software within CDMD-OA (NAVSEA Data Environment – Navy Modernization).
