Our guest today has been at the forefront of operational reliability improvement in various industries around the world for many years. Dick Pettigrew joins us today, sharing from his extensive experience as we discuss his integrated approach to design, maintenance and operations.   With a degree in Chemical Engineering and a love for machinery, Dick started out working in process engineering support. As he progressed into design and project management, Dick began to observe fundamental issues surrounding the approach to reliability improvement and maintenance operations. In this episode, Dick shares about his career journey, some of the major learnings of his experience thus far and his holistic approach to problem solving on site, not just within maintenance reliability.   We discuss how output improvement is more valuable than maintenance cost reductions, how there’s a difference between the problem and the cause and that taking a broadened approach from reliability improvement into total manufacturing improvement is what will create sustainable improvements.   Dick talks us through some of his experiences improving outcomes and how the assessment process itself isn’t as important as the commitment from the leadership team and people on site to implement the improvements. We discuss the importance of establishing a good culture and how working with people directly on the floor brings the plant up to standard and restores pride in the operation.   Dick has spent a lot of time creating measurement systems and writing books to take a systematic approach to output improvement. He discusses his asset utilisation model and how combining this with the theory of constraints enabled him to improve the output of many plants he’s been involved in.   We discuss using RCM not as a project but as a way of thinking about plant reliability and how it can make a real difference when utilised this way. Dick shares his advice to aspiring maintenance and operational managers, honing in on the vital component of the human aspect.
