It can be easy for those of us in the embedded industry to think of obsolescence as predominantly an electronics or software issue and to imagine its scope as limited to small- or medium-scale consequences. Unfortunately, the harsh reality is that obsolescence is a problem across many industries, and the consequences can be severe. The […]
It is strange how onboarding the concept of legacy sustainment can change the way you look at the world around you. On a recent road trip along one of the nation’s many two-lane highways, I found myself wondering about the thousands upon thousands of wooden utility poles dotting the landscape. How often are they repaired? […]
“Proactively consider DMSMS through[out] a system’s life cycle by anticipating potential DMSMS occurrences and taking appropriate logistics, acquisition, and budgeting steps to prevent DMSMS from adversely affecting readiness or total ownership cost.” SD-22 DMSMS Guidebook Continued from a previous post: Being Proactive While obsolescence management traditionally starts after products become mature, that is really waiting […]
“Proactively take timely and effective actions to identify and minimize the DMSMS impact on DoD acquisition and logistics support efforts.” SD-22 DMSMS Guidebook The DMSMS conference is just around the corner. As a conference all about obsolescence management, it tends to be one we look forward to every year. This year, we’re looking to take […]
With the dialog about counterfeits in the supply chain, it is easy to lose track of what counterfeits actually mean. Yes, they will hurt your business. Yes, they can lead to heavy penalties and jail time, but counterfeits can also lead to jeopardizing lives; a risk that could otherwise have been avoided.
I am always looking for recent numbers and reports to keep the topic fresh and moving forward. But, recently, as I researched my paper for the upcoming SMTA International conference, I’ve come across some new numbers that drives home, once again, how vulnerable everyone is to the issues around counterfeits.
I personally take an average of 2-4 flights every month. According to the FAA, the amount of travel Americans are doing both for business and recreation is increasing. It is projected that the total number of people flying commercially on U.S. airlines will increase from 732 million to 746 million in 2013, and increase to 1.2 billion by 2032. And in 2010 the FAA estimated that some 520,000 counterfeit parts make their way into planes each year.
Saying that something is “good enough for government work” is often meant as a joke and the reference implies “mediocre work.” The irony is that “government work” is often highly sophisticated; systems are designed and engineered to operate in the most extreme environmental conditions for a very long period of time.
I recently had the pleasure of having lunch with a talented component engineer who has spent much of his career working in the defense industry. During the course of our discussion I learned that some aviation systems need ICs to operate in temperature extremes ranging from -55°C to 125°C; ground units often travel in harsh environmental conditions (e.g. fighting extreme heat and sand storms in deserts) while being exposed to hostile attacks; satellites traveling through orbit are exposed to protons and heavy ions from solar flares, yet must operate reliably in space.
Throughout my work with GDCA and all the issues around obsolescence, I have never come across someone who believes that obsolescence is something to be celebrated and welcomed. Everything associated with obsolescence is considered something to be avoided. The concept of planned obsolescence brings with it connotations of either designing a product to wear out […]
In general, defense sustainment and counterfeit avoidance has been left to DMSMS teams and logistics or engineering tactics. However, so far the solution has primarily been to develop standards, authentication and anti-counterfeit technologies. These responses have been critical, but have largely remained reactive and have not produced the dynamic collaboration crucial to maintaining a healthy, proactive supply chain. Instead, each player is left facing inward — focusing on solutions from their own particular positions in the supply chain — but without the resources to truly be proactive.
In the past we’ve talked about the challenges of Last-time Buy and overstock. In Dr. Sandborn’s CALCE Obsolescence Management training, this question illustrates the challenges and risks in regards to what customers can face, at the time of EOL. The answer might be easy if you were looking at a “bridge buy”, where you only need enough to get you to the point of a planned upgrade. If I had to only buy shoes to get me through five years it would be challenging but I could probably come up with a pretty good estimate based on the last five years of my life.
No matter what your opinion; DNA tagging is currently one of the top methods being discussed to ensure component authentication. The Defense Logistics Agency (DLA) even issued a Request for Information on the subject.
Unfortunately, due to the costs projected and associated with DNA tagging and authentication, few businesses appear to be looking forward to the prospect.
At first glance DNA tagging, like many of the industry’s current solutions, makes sense: increase the complexity of the marks so that counterfeiters are unable reproduce it. DNA would be a “tag” both difficult and expensive to try and recreate. However, DNA tagging and many of the solutions being proposed are “point forward” solutions that, in order to be truly effective, would need to be implemented at the component manufacturing level, not once parts have left the factory floor.
