Embedded Systems at Cargill This is a report on a session at a Y2K conference about the method Cargill has developed to do I&A on embedded systems in small to medium size plants. I am posting here the section which mentions TAVA, and including a link to the entire report, which is quite long but very interesting. Year2000.com Announcement List, Special Mailing, July 15, 1998 by Jon Huntress When you look at the numbers -- trillions of lines of computer code, billions of embedded chips and millions of dollars to find and fix everything, it is easy to get depressed, come to the conclusion that there is no way out, and that the gloom and doomers are right. Society as we know it is going into the toilet, or I should say the outhouse, because the toilets won't work anymore because the pumps that move the water to the water towers will stop working because of the embedded chips on the automatic controls and valves. That's what a guy at the next table told me. How many of you out there remember the expression, "rougher than a cob?" This was in my mind when I attended a session put on by Philip Hannay of the Cargill Company. The Cargill Company started in Iowa, just like I did, and they are well known for agricultural products and services. They would certainly benefit if it became necessary to go back to the time when a box full of corn cobs was a necessary accessory to every outhouse. But Philip was telling the audience a different story. He said that while the problem was real, it wasn't all that bad. In the plant environment, many of the embedded system problems are minor if known about in advance, solutions are straightforward, work-arounds can save time and money, and that "wait and see" for non-critical applications is an option. A consultant in front of me was getting visibly upset at those conclusions. What Philip was recommending, he whispered to me, was too loose, too unstructured, too fast, to deal with the embedded systems most factories have. I was coming to a different conclusion. I think Philip Hannay is a genius. So I warn you, there will be wide differences of opinion on the embedded systems assessment, inventory and remediation techniques recommended by Hannay. In a future report I will contrast this with TAVA's approach to the same problem with some major companies. They are quite different, and yet Ken Owen of TAVA brought Mr. Hanney to the conference, introduced him and sat behind him for the presentation. During the talk, Mr. Hanney told everyone to put off calling the big consulting companies until they had completed their own inventory and made their own plan. This is another case of people working together for the good of everyone, even though it seems to be counter to their own interests. TAVA needs to be congratulated for their forward thinking and ecumenical attitude. There are differences that make the both approaches worthwhile, but the Cargill approach hasn't been presented as a complete plan before. Link to complete article:Message 5210357
