Sustainment Resource Hub
Sustainment is no longer just about managing obsolescence—it’s about recognizing that obsolescence happens, and developing better ways to respond. Ten years ago, pre-stocking was the only real tool in the toolbox. Today, lifecycle assurance, sustainment engineering, and new sources of supply are reshaping how embedded systems stay mission-ready for the long haul.
At GDCA, we’ve spent decades building that shift—helping programs move from reaction to resilience. This Resource Hub brings together insights, strategies, and tools for navigating embedded sustainment in the real world. Whether you're new to the space or looking to sharpen your approach, you'll find practical guidance and field-tested insights here.

Legacy Systems Aren’t a One-Time Fix: Why Proactive Obsolescence Management Matters
The Cost of Treating Sustainment Like a Fire Drill When a part goes obsolete, the response isn’t routine—it’s destabilizing. Engineers are pulled off deliverables. Procurement shifts into emergency sourcing. Operations waits without clear direction while…
Why You Can’t Engineer Your Way Out of Legacy: A Sustainment Strategy for Long-Lifecycle Systems
The Myth of “One Last Redesign” When legacy pressure builds, the instinct is familiar: redesign the board, refresh the architecture, modernize the specs, and buy another decade of support. On…
Legacy Sustainment In-House: Hidden Risk for Embedded OEMs
What Happens When Embedded OEMs Keep Legacy Sustainment In-House? A quiet erosion that often ends in a sudden catastrophe. The risk isn’t always a single, dramatic event; it’s a slow, silent drift. Systems degrade.…

Proactive management in all phases of a life cycle is crucial to avoid costly component replacements, ensure critical weapons system readiness, and reduce risks to warfighters.
When it is understood that traditional obsolescence management itself often starts too late in a program’s life cycle, we see the need to address ongoing risk from a different angle.
