Legacy Systems Aren’t a One-Time Fix: Why Proactive Obsolescence Management Matters
March 9, 2026
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 schedules slip and earned value begins to drift. Program managers must explain impacts before full visibility exists. The disruption moves fast. Production slows. Repair turnaround…
Why You Can’t Engineer Your Way Out of Legacy: A Sustainment Strategy for Long-Lifecycle Systems
February 18, 2026
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 paper, it feels decisive. Engineering is engaged. A technical solution is in motion. But in long‑lifecycle systems, redesign rarely eliminates legacy risk. More often, it resets the clock…
Legacy Sustainment In-House: Hidden Risk for Embedded OEMs
February 9, 2026
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. Critical knowledge walks out the door. Customers grow frustrated. And leadership is often unaware of just how fragile their internal support has become until it’s too late. …
Why you can’t engineer your way out of Legacy
February 3, 2026
The Myth of “One Last Redesign” Application OEMs often fall into a familiar trap: when legacy pressure builds, the next redesign is expected to solve it. One more refresh. One more board update. Another attempt to buy ten more years of support. On paper, it feels rational. Engineering is engaged. Specifications are modernized. A technical path…
The Cost of Delay (ROI Aligned)
January 20, 2026
The Cost of Delay As a Product Manager, you make hundreds of decisions a week. But what about the one you keep putting off? The one about the long tail of legacy products. We’ve all done it. We look at a complex, non-urgent problem and we decide to wait. “We’ll get to it next quarter,” we…
Understanding the True Cost of Tech Obsolescence
December 14, 2025
Do we, as an industry, truly understand the full impact and cost of tech obsolescence? Over the past years, the team at GDCA has been doing our best to educate and illuminate the electronics industry on the impact that obsolescence has on every level of our supply chains. Traditionally, product obsolescence was simply managed in-house,…
Staying Mission Ready: The Importance and Value of Extending Legacy Equipment Lifecycles in Critical Defense Programs
October 30, 2025
In previous articles, we’ve discussed the massive, costly impact that electronics obsolescence has on Defense programs. Few industries feel the effects of this problem the way that Defense manufacturers, contractors, and programs experience it. Many of the electronic systems deployed for use in these applications will be needed for ten years or more, often upwards…
Managing Electronic Component Obsolescence in Defense Programs
October 1, 2025
The problem of electronics obsolescence is uniquely potent when it comes to Defense programs. Modern Defense electronic systems tend to be rife with obsolete components or components at risk for being discontinued–some of which are mission-critical for the larger system. So not only is electronic obsolescence more prevalent, it also tends to have a much…
Strategies for Effective Part Obsolescence Management in Electronic Infrastructure Systems
June 3, 2025
As a society, we are incredibly dependent on our smartphones and devices, whether we want to admit it or not, for many crucial aspects of our daily lives. But imagine one day that your smart phone just stops working. No calls, no texts, no internet connection. You can’t access your emails, your personal and office…
Understanding and Mitigating Obsolescence Risks in Embedded Systems
January 10, 2025
Electronics obsolescence is an inevitable and fundamental problem that many manufacturers and end-users face daily with their embedded systems. But it doesn’t have to be a big challenge–proper planning and support can help you save a lot of time, money, and effort that would otherwise be wasted trying to ‘manage’ obsolescence risk when it’s such…
