Abstract: The problems and experiences from about thirty years in the reliability prediction of electronic equipment using MIL-HDBK-217 and teaching reliability and maintainability theory in higher education are discussed in this work. Because the MIL-HDBK-217 has limitations, and has not been updated since 1995, RIAC introduced new methodology, based on PRISM, and new MIL-HDBK-217Plus, but application of this methodology can be more time consuming, more costly, and MIL-HDBK-217Plus is no longer free. So, for small companies it is not cost effective. But are predictions by this new methodology always more accurate, and what if there is no enough data to applicate this methodology? These problems are also discussed in this work. Software and human reliability, reliability of cloud services, reliability of internet of things and reliability culture will also be mentioned.

Keywords: reliability, reliability prediction, hardware, software, human, cloud services, internet of things, culture.
