【正文】 probability that a program is operating according to requirements at a given point in time and is defined as Availability = [MTTF/(MTTF + MTTR)] x100% 20 Safety ? Software safety is a software quality assurance activity that focuses on the identification and assessment of potential hazards that may affect software negatively and cause an entire system to fail. ? If hazards can be identified early in the software process, software design features can be specified that will either eliminate or control potential hazards. 討論和作業(yè) ? 一個(gè)正確的程序還能不可靠嗎？ ? 一個(gè)正確的程序還能不表現(xiàn)高質(zhì)量嗎？ ? 除了統(tǒng)計(jì)錯(cuò)誤和缺陷外，還有那些軟件特征具有質(zhì)量意義？ ? 給出兩個(gè)安全性至關(guān)重要的計(jì)算機(jī)控制系統(tǒng)，并為每個(gè)系統(tǒng)列出至少 3條與軟件失效直接相關(guān)的災(zāi)難。 22 ISO 9001:2022 Standard ? ISO 9001:2022 is the quality assurance standard that applies to software engineering. ? The standard contains 20 requirements that must be present for an effective quality assurance system. ? The requirements delineated by ISO 9001:2022 address topics such as ? management responsibility, quality system, contract review, design control, document and data control, product identification and traceability, process control, inspection and testing, corrective and preventive action, control of quality records, internal quality audits, training, servicing, and statistical techniques.
