Critical Thoughts on Embedded Sustainment & Obsolescence
Critical Thoughts is where we share hard-won insights from the field. It’s not a blog—it’s a working record of what we’ve learned supporting sustainment, managing obsolescence, and partnering with OEMs on legacy challenges that don’t fit the usual models.
These are the strategic, technical, and sometimes messy realities behind keeping embedded systems mission-ready over the long haul.
Whether you’re checking out his illuminating talks on the nature of the universe, theoretical cosmology and quantum gravity; watching him play himself on Star Trek: The Next Generation, The Simpsons and Futurama; or geeking out to MC Frontalot’s rap, science, and quotations; chances are you’ve heard Stephen Hawking’s iconic voice. What most people don’t realize is that while…
Following its development in the late 1970s by Motorola, VME bus continues to see wide use across many different equipment industries today. In fact, the first COTS VME boards to enter the domestic market (c 1983) were the MVME101 CPU and MVME110 CPU, both of which are still supported by GDCA today (though no one’s asked in…
The resolution of obsolescence for mission-critical electronics systems is of utmost importance. Obsolescence issues affect almost every electronics system that is maintained long-term. Arlin describes specific issues and suggests solutions to sustain those systems, focusing on the option to remanufacture obsolete systems. Key considerations include startup and material costs, along with hardware design and program…
