There are also significant international variations in industrial practices, which are also reflected in standards, the goal of a system reliability program is to predict the trouble-free lifetime of a system and to determine ways to extend it. Coupled with, increased system performance monitoring and improved failure investigations that identify underlying system failures.
Alternatively, the system can be hierarchically divided into subsystems and modules as required, with the trend of increasing technological complexity, software content and mechatronic implementation, there are increasing risks from systematic failures and random hardware failures.
