This book analyses and proposes solutions to one of the core challenges faced in the Maintenance, Repair and Operations (MRO) supply chains in the oil and gas industry, a field that is currently impacted by low oil prices, emerging technologies and a societal transition to cleaner energies. It describes the end-to-end nature of the oil and gas supply chain, and challenges paradigms and accepted ways of working within the industry ¿ such as wastes driven by broken interfaces, naivete regarding supply chains, and the practice that considers re-organisation to be the answer to these challenges ¿ and identifies opportunities to shift this paradigm towards reliability and value. Moreover, the book shares the authors¿ front-line experience and encourages readers to consider deploying the solutions presented in their own contexts. The insights from the book¿s 12 modules are based on personal experiences and are industry-generic, allowing them to be transferred to other MRO supplychains. Readers are encouraged to use this book as a reference for their own supply chain transformations. The book is primarily intended for practitioners, including chief operating officers, chief financial officers, chief supply chain officers, engineers and heads of procurement, purchasing, operations, and materials management.
