Even companies that primarily focus on the technical development and manufacturing of their products must acquire new customers and retain them in the long term. This book provides a guide for the transition to an industrial service company: Using examples from leading industrial enterprises (automotive, mechanical engineering, information technology), it explains which concepts lead to sustainable success. It includes tools for assessing one's own service performance and maturity, step-by-step instructions, and recommendations for action. Leading industrial companies have recognized that developing and manufacturing technically high-quality products alone is no longer sufficient to achieve ambitious revenue and profit targets. To retain customers profitably and in the long term, targeted service innovations and a focus on service delivery are necessary.
