When - PRECISELY - will the agreed reliability target be met?Does your reliability improvement journey feel like a decade-long tortuous path to ... somewhere? Or a direct, Line-of-Sight flight to Best-In-Class performance?Credible reliability leadership is quantitative, with the goal of finishing the journey, rather than embarking upon it.Steering the behavior of a complex production system requires more than expertise and tools. It requires INSIGHT into the nature of the complex, stochastic problem.Credible Reliability Leadership introduces the Concepts, Methods and Tools, that constitute the RAMS Mentat approach to Systems Reliability Engineering. The provided insights have implications for many aspects of reliability and maintenance management in a process plant environment.
