Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system. For example, an automobile's failure rate in its fifth year of service may be many times g… WebJul 25, 2024 · Referring to elements of service quality, empathy is the highest factor influencing patient satisfaction (Beta=0.411, p<0.001), followed by reliability (Beta=0.183, p<0.05), tangibles (Beta=0.119 ...
