Stories of embedded systems failures:   Embedded Systems - the problem is real

- --- Year 2000 and Manufacturing Companies ------

OFFICIAL RELEASE -- October 28, 1997

The Year 2000 user groups co-sponsoring the joint position statement are as follows:

- -- Tennessee Y2K Issues Group in Nashville, Tennessee

- -- Midwest 2000 Sharing Group in St. Louis

- -- Arizona Millennium Group in Phoenix

- -- New York 2000 User Group

- -- "The Nutmeg Centurians" in Trumbull, Connecticut

- -- Society for Information Management (SIM) Year 2000 Working Group

- -- Central Indiana Year 2000 User Group

- -- Bluegrass Year 2000 Group in Lexington, Kentucky

We have not had any user group decline involvement.

- ----- JOINT POSITION STATEMENT --------------------

"Embedded Systems" include microprocessors and computer chips embedded in many process controls, sensors and other devices. These systems often require someone with detailed product knowledge to identify the component and test it. In many instances, only the vendor or their supplier is in a position to know how to fix the embedded system. Older equipment may no longer be supported by the original equipment manufacturer, and an upgrade or replacement is required.

These embedded systems need to be identified, evaluated, corrected where needed, tested, the testing documented, the results reviewed for validity, and other adjustments made. This is all easy to say but it can be very difficult and time consuming to achieve. Studies and reports indicate that very few organizations have even begun to fix their embedded systems problems.

Has your organization already determined that it does not have embedded system problems? What level of business risk is there to your organization from embedded systems failures? What level of business risk is there in "not knowing" about potential failures of your suppliers, customers, and service providers? It is our understanding that nearly every manufacturing company, which has thoroughly checked, has identified some embedded systems problems. If these outside organizations have a problem, it could disrupt your business. We want to encourage everyone to take steps to avoid disruptions due to Year 2000 computer problems within their own, their suppliers, or their customers embedded systems.
