The Sustainment Gap: Why Technical Data Alone Isn’t Enough for Legacy Systems
June 1, 2026
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 follow. On paper, it feels logical. The design exists. The documentation exists. The product should now be reproducible. But many organizations discover the same reality…
The Real Risk of Legacy Products Is Reputation
May 19, 2026
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. Strategic customers expect continuity. When legacy products fail in the field or can’t be supported, they don’t just blame the product—they question the company. Legacy Isn’t Neutral Holding on to legacy…
Last Time Buy Isn’t a Long-Term Solution: Managing Obsolescence Risk in Legacy Systems
April 28, 2026
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, and execute a last time buy before supply disappears. It feels like control—the risk is identified, the inventory is secured, and the issue is closed. Until…
LEM vs Vendor: Why OEMs Need a Legacy Equipment Manufacturer for Long-Term Sustainment
April 9, 2026
If you treat legacy like a transaction, you’ll keep paying for it. Many OEMs think of end-of-life and sustainment transfers as a simple handoff. You document the product, pick a vendor, issue a PO, and move on. But what happens when that “simple” PO fails an audit? Or when a critical DoD program is grounded because that…
Product Portfolio Optimization: Why OEMs Should Transfer Aging Product Lines Now
March 31, 2026
Managing Product Portfolios in Uncertain Markets: Why Now’s the Right Time to Transfer Aging Product Lines In volatile markets, every product in your portfolio should justify its place. If legacy lines aren’t delivering growth or strategic value, why are you still carrying them? For Embedded OEMs, the challenge isn’t just about cutting costs—it’s about ensuring that every product in the portfolio actively…
Planning for Legacy Sustainment Isn’t Optional — It’s a Business Decision You’re Already Making
February 3, 2026
The Cost of Waiting: Why Legacy Failures Are Always More Expensive Later Legacy systems rarely fail all at once. They fail quietly—and expensively. A component reaches end-of-life. A supplier exits the market. Test capability erodes as documentation ages and people move on. None of it feels urgent in isolation. But together, these small degradations create something far…

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…

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…
