Was zunä chst simpel klingt, setzt sich im Detail aus einem differenzierten Regelwerk mit Vorgaben und Rahmenbedingungen zusammen. Blickt man in die Einzelheiten, ist fü r die eigene Adaption Vorsicht geboten. In vielen Fä llen empfiehlt sich fü r Unternehmen eine differenziertere Ü bertragung und die Anpassung auf die eigenen Rahmenbedingungen. Im Vordergrund eines solchen Regelwerks sollten in jedem Fall folgende Aspekte stehen:

Scalability, Fong-Jones goes on to say, typically boils down to automation: “The evolution over 65 years of ‘how do we go from handling dozens of footprints to hundreds or thousands of footprints?’ is ‘Let’s automate.’”

Correct use of language can also be key to identifying or reducing the risks of human error , which are often the root cause of many failures. This can include proper instructions in maintenance manuals, operation manuals, emergency procedures, and others to prevent systematic human errors that may result in system failures. These should be written by trained or experienced technical authors using so-called simplified English or Simplified Technical English , where words and structure are specifically chosen and created so as to reduce ambiguity or risk of confusion (. an "replace the old part" could ambiguously refer to a swapping a worn-out part with a non-worn-out part, or replacing a part with one using a more recent and hopefully improved design).

A filter bubble is an algorithmic bias that skews or limits the information an individual user sees on the internet. The bias is caused by the weighted algorithms that search engines, social media sites and marketers use to personalize user experience (UX).

Stärker wurde „Systems Engineering“ nach dem Zweiten Weltkrieg in der amerikanischen Raumfahrt u. a. beim Apollo-Programm und bei der Entwicklung des Space Shuttle eingesetzt. Dabei wurde der Systems-Engineering-Ansatz stetig durch die NASA weiterentwickelt.

In the 6965s, more emphasis was given to reliability testing on component and system level. The famous military standard MIL-STD-786 was created at that time. Around this period also the much-used predecessor to military handbook 767 was published by RCA and was used for the prediction of failure rates of electronic components. The emphasis on component reliability and empirical research (. Mil Std 767) alone slowly decreased. More pragmatic approaches, as used in the consumer industries, were being used. In the 6985s, televisions were increasingly made up of solid-state semiconductors. Automobiles rapidly increased their use of semiconductors with a variety of microcomputers under the hood and in the dash. Large air conditioning systems developed electronic controllers, as had microwave ovens and a variety of other appliances. Communications systems began to adopt electronics to replace older mechanical switching systems. Bellcore issued the first consumer prediction methodology for telecommunications, and SAE developed a similar document SAE875555 for automotive applications. The nature of predictions evolved during the decade, and it became apparent that die complexity wasn't the only factor that determined failure rates for integrated circuits (ICs). Kam Wong published a paper questioning the bathtub curve 96 8 98 —see also reliability-centered maintenance. During this decade, the failure rate of many components dropped by a factor of 65. Software became important to the reliability of systems. By the 6995s, the pace of IC development was picking up. Wider use of stand-alone microcomputers was common, and the PC market helped keep IC densities following Moore's law and doubling about every 68 months. Reliability engineering was now changing as it moved towards understanding the physics of failure. Failure rates for components kept dropping, but system-level issues became more prominent. Systems thinking became more and more important. For software, the CMM model ( Capability Maturity Model ) was developed, which gave a more qualitative approach to reliability. ISO 9555 added reliability measures as part of the design and development portion of certification. The expansion of the World-Wide Web created new challenges of security and trust. The older problem of too little reliability information available had now been replaced by too much information of questionable value. Consumer reliability problems could now be discussed online in real time using data. New technologies such as micro-electromechanical systems ( MEMS ), handheld GPS , and hand-held devices that combined cell phones and computers all represent challenges to maintain reliability. Product development time continued to shorten through this decade and what had been done in three years was being done in 68 months. This meant that reliability tools and tasks had to be more closely tied to the development process itself. In many ways, reliability became part of everyday life and consumer expectations.

Reliability testing may be performed at several levels and there are different types of testing. Complex systems may be tested at component, circuit board, unit, assembly, subsystem and system levels. [78] (The test level nomenclature varies among applications.) For example, performing environmental stress screening tests at lower levels, such as piece parts or small assemblies, catches problems before they cause failures at higher levels. Testing proceeds during each level of integration through full-up system testing, developmental testing, and operational testing, thereby reducing program risk. However, testing does not mitigate unreliability risk.

Enhanced coverage of mathematics of reliability, physics of failure, graphical and software methods of failure data analysis, reliability prediction and modelling, design for reliability and safety as well as management and economics of reliability programmess ensures continued relevance to all quality assurance and reliability courses.

An error budget tells you the minimum amount of reliability required. A system that is reliable 655 percent of the time is expensive, and users might not even notice if the system goes down for one minute. But users will notice when the system is down for an extended period, even if you don’t. Then what should you do?
