GCSS-MC Capability Support and Decommissioning Services

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the sustainment and decommissioning of the Global Combat Support System-Marine Corps (GCSS-MC) system. It clarifies requirements, technical details, and operational expectations for potential bidders.

• Oracle Licenses: The Government owns perpetual Oracle E-Business Suite (EBS) licenses for GCSS-MC, including Oracle Database 19c, OAM 12c, OIM 12c, OID 12c, and EBS 12.2.5. These licenses are term-based and sufficient for sustainment. OEM support is not mandated.
• System Changes: The GCSS-MC system will only receive break/fix and cybersecurity-driven changes. No new capabilities will be added. Updates outside these boundaries require Government authorization.
• Cybersecurity: The contractor will support full ATO reauthorization cycles and is expected to generate, review, and update cybersecurity documentation as required by DoD RMF processes. Known POA&Ms, audit findings, and vulnerability trends must be managed through End of Life.
• User Support: Tier 1 and Tier 2 user support will be contractor-provided. The contractor will integrate with and manage the existing Government-led operations center.
• Decommissioning: The Government targets a 3-year window for GCSS-MC decommissioning. The contractor will be responsible for data archiving, all documentation, and collaborating on transition efforts, including data migration and interface management with the successor system.
• Competition: The Government will conduct a full and open competition, and small business subcontracting goals are not expected.

This Q&A document clarifies key aspects of the Performance Work Statement (PWS), including the scope of work, performance standards, and responsibilities related to system sustainment, cybersecurity, and decommissioning. Bidders should review these clarifications to accurately prepare their proposals.

Statement of Work (SOW) / Performance Work Statement (PWS)

This Performance Work Statement (PWS) outlines the requirements for providing Post Deployment System Support (PDSS) for the Global Combat Support System – Marine Corps/Logistics Chain Management (GCSS-MC/LCM) Increment 1 system. This includes migration to Cloud One, sustainment in the cloud environment, and decommissioning of the system.

• Service Management: Defining and managing service levels, monitoring performance, and recommending enhancements.

• Service Operations: Executing day-to-day processes for reliable service delivery, including Enterprise Service Desk and GCSS-MC Operations Center (GOC) support.

• GCSS-MC Production/PSS Environment Sustainment: Maintaining the current production and production support systems in the GCSS-MC Cloud One environment, including troubleshooting and corrective actions.

• Solution Development Environment: Supporting the development, testing, and configuration management of the GCSS-MC/LCM Increment 1 application.

• Enterprise Training and Training Devices: Providing integrated training management, delivery, and sustainment of training materials and devices.

• Product Lifecycle Support: Ensuring reliability, availability, and maintainability (RAM) of the system, including asset tracking, license management, warranty support, and obsolescence management.

• Service Transition: Planning and executing all system changes, including break fixes and cybersecurity updates.

• Systems Engineering Supporting Activities: Maintaining the system through root cause analysis, upgrades, and technical refreshes.

• Program Management: Planning, administration, execution, reporting, and continuous improvement of cost, schedule, and performance.

• Contract Transition: Minimizing impacts to system operations during transition-in and transition-out periods.

• The document references various metrics and Key Performance Indicators (KPIs) for service delivery, incident resolution, and system performance. Specific metrics for Service Desk performance are detailed in Table 4.

• Reliability threshold: 99.44% (objective 99.99%).

• Operational Availability threshold: 95.00% (objective 98.00%).

• Maintainability threshold: no more than four (4) hours of system downtime for 90.00% of downtime occurrences.

• The PWS covers Post Deployment System Support (PDSS) for GCSS-MC/LCM Increment 1.

• Specific locations for performance are not detailed in this document, but travel may be required to CONUS/OCONUS locations.

• Security: Adherence to DoD and Marine Corps security regulations, including personnel clearances, access control, and cybersecurity requirements (DoDI 8500.01, DoDI 8510.01, etc.).

• Personnel: Contractor personnel must meet specific qualifications and certifications, including IA/Cybersecurity certifications.

• Americans with Disabilities Act (ADA): GCSS-MC software must be compliant with Section 508 of the Rehabilitation Act.

• Government Furnished Information (GFI): Access to GFI will be provided, and contractors must adhere to non-disclosure agreements.

• Transition: A transition-in period of 6 months is required upon contract award, and a transition-out period of 6 months will occur on the final contract.

Request for Information (RFI)

This RFI is issued by the Marine Corps Systems Command (MCSC) to conduct market research for capability support and decommissioning services for the Global Combat Support System Marine Corps (GCSS-MC). GCSS-MC is an Oracle-based Enterprise Resource Planning (ERP) system used for logistics, supply, and maintenance operations. This RFI is for information and planning purposes only and does not constitute a Request for Proposal (RFP).

The government is seeking industry interest in services for:
