The GCSS-Army program is an Enterprise Resource Planning program begun in 2003. Following the blueprinting, development and testing phases, the US Army Test and Evaluation Command conducted Operational Assessments in 2007 and 2010, followed by the Initial Operational Test and Evaluation in 2011 and Lead Site Verification Tests in 2012. In December 2012, the Milestone Decision Authority granted the full deployment decision for the first increment of GCSS-Army, which included warehouse, ground maintenance, property accountability, unit supply and tactical financial management functionality. From February 2013 through 2017, the full system deployment took place in all Army components, world-wide, reaching over 100,000 users. While the GCSS-Army program has transitioned sustainment of the Baseline solution to the Army Shared Services Center, the Product Office is delivering new capability with the development, testing and deployment of an Aviation Logistics solution, as well extending the baseline to support Army Prepositioned Stocks and Medical Logistics. In spite of the challenges encountered due to COVID-19 restrictions, the program has succeeded in delivering crucial capabilities to the tactical Army. The Product Office stands ready support the warfighter and the Army’s modernization efforts.

Product Managers are responsible for the overall and ongoing success of a product. The Product Director is required to manage the product through the entire lifecycle. The Product Director is required to stand up all product management divisions including Product Director, Technical Management and Logistics Lifecycle.


The Program Management Division (PMD) provides oversight and support to a variety of Project Management wide initiatives. PMD serves as the Product Director Office’s (PDO) focal point for budget and contracting coordination, planning and analysis, and operational support. PMD manages functional support agreements for PDO services, planning and programming, budget execution, acquisition, and financial management. PMD provides acquisition guidance, oversight, and assistance to the Product Director, to include development and staffing of acquisition documentation and policy and regulation adherence to cost, schedule, performance, and supportability objectives for all PD GCSS-Army divisions. In direct interaction with the Project Manager Defense Integrated Business Systems, PMD manages acquisition reporting, decision scheduling, and coordination of official acquisition document approval. PMD also manages strategic communications, program transitions, congressional affairs, program progress reviews and audit inspections, serving as the primary focal point for all external audits performed by external audit agencies and providing liaison support to GCSS-Army Division Chiefs.


The Systems Engineering (SE) Team provides direct SE support to PdM GCSS-Army and oversees the Lead System Integrator’s SE, Technology, and Basis Teams’ activities and product development. The SE Team oversees/manages the activities that occur for all landscapes at the Production and Disaster Recovery Data Centers (i.e. maintenance windows, HW/SW upgrades, DISA Migration planning and execution, etc.). The SE Team serves as the Cyber Security lead for the program and provides the GCSS-Army Information System Security Manager (ISSM) and supporting Information System Security Officers (ISSOs) to manage system Certification, Accreditation, Technical Authorizations, and Risk Management Framework (RMF) compliance. This team also manages IAVA compliance at both the data centers and for the client software configurations. The SE Team creates/tests/maintains the client software baseline (including Windows upgrades), delivered by the LSI, that is sent to the field. The SE Team serves as technical lead for the program’s Configuration Control Board (CCB), Configuration Review Board (CRB), and Risk Management Board and provides technical support to the program’s Configuration and Release Managers in support of Sustainment Release activities. The SE Team supports audit activities, implementation of mitigation solutions and is responsible for the development of the program’s Technical Acquisition documentation.


The Technical Division provides oversight and support to a variety of PMO initiatives. This includes the complete technical over site of a systems life cycle from concept to deployment and sustainment. The Technical Division comprises of the engineering team that evaluates IT systems in accordance to functional requirements and current operating environments. Assess the performance of the system and cost reduction potential of advanced technologies. The test and evaluation team manages all acceptances testing to ensure each product meets the requirements of the functional organization.


Involves Integrated Logistics Support (ILS) to integrate an iterative process for assuring supportability of an acquisition system. Supportability is the degree of ease to which system design characteristics and planned logistics, resources, including logistics support elements, allow for the meeting of system availability and user wartime and peacetime requirements. LMD will systematically identify, produce, acquire, deliver, install, and upgrading logistics support capability requirements through the acquisition process for PEO EIS systems, subsystems, and equipment. This function includes the oversight, direction, and control of subordinate logistics offices and agencies through developing and issuing logistics policies and providing policy guidance; reviewing, analyzing, and evaluating performance (e.g., logistics systems reinvention and modernization).


The GCSS-Army Aviation Logistics (AVLOG) team is responsible for developing, testing, evaluating, and integrating with the GCSS-Army baseline, and for deploying and providing initial capability support of the Enterprise Aviation solution and ongoing? capability support to the Aircraft Notebook. Capabilities include Aviation Master Data within Army Enterprise Systems Integration Program (AESIP) Hub (Release 1A) in December 2019 and Off-Platform DA Form 2410 Equipment Repair within GCSS-Army (Release 1B) in late January 2020. Release 1A offers an application for TAMMS-A (The Army Maintenance Management System-Aviation) personnel to manage Aviation Master Data in the AESIP Hub and systematically syndicates this data from AESIP Hub through GCSS-Army down to the ACNs. Release 1B makes available the capability for second level repairs by Aviation Classification Repair Activity Depot (AVCRADS), Theater Aviation Sustainment Maintenance-Group (TASM-G), Regional Aviation Sustainment Manager (RASM), and Aviation Field Maintenance Directorate (AFMD). GCSS-Army Aviation Logistics includes both the Enterprise Aviation and Aircraft Notebook teams. As a part of PD GCSS-Army, Aviation Logistics works collaboratively with personnel of all GCSS-Army Divisions located at both Ft. Lee, VA, and Redstone Arsenal, AL.
