Werner and Dave, Thanks for the input. The froth I'm not yet displaying concerns how the DoD folks keep asking for compliance with the standard/spec. There are some still asking for use of statistical methods, FMEA processes, and use of 217. What's with this? Also, though not asking Werner to give up any secrets about his reliability consultancy, what are we "civilians" using as prediction methods/standards? I know some, but seems a target rich environment beyond past histories, especially concerning "breakthrough" technologies, let alone evolutionary types. All the disk drive manufacturers, as but one minor example, state a MTBF number usually around 300,000 hours or more. I've been involved with them from a DFM standpoint and some simply have "great" warranty/exchange programs. Hope my latest Maxtors hold up for another 300 hours. Sure hope "old Jim M's" stuff flies well, as well, oh well. Reminds me of a Waylon song with verse as my front tracks are headed for a cold water well and my back tracks are covered with snow. Willie was part of this as well. What comes around?
