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.

The Sustainment Gap: Why Technical Data Alone Isn’t Enough for Legacy Systems
The Illusion of “Having the Data” For many organizations, legacy systems sustainment begins with a simple assumption: acquire the Technical Data Package (TDP), transfer the data internally, and supportability will…
The Real Risk of Legacy Products Is Reputation
For Embedded OEMs, the risk of legacy isn’t just technical—it’s reputational. When aging products remain in your portfolio without a clear plan for support, the brand you’ve worked so hard to build is what takes the hit. …
Last Time Buy Isn’t a Long-Term Solution: Managing Obsolescence Risk in Legacy Systems
Why last time buys fail—and how a structured sustainment strategy protects long-lifecycle programs from recurring supply chain disruption When a critical component goes obsolete, the response is immediate: forecast demand, secure funding,…

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.
