Services in the industrial sector—commonly referred to as industrial services—are an important source of profit, differentiation and future growth for their providers. This sector includes industries such as heavy equipment manufacturing, energy production, chemical production and oil and gas. Despite its importance, neither the term industrial service(s) nor its concrete subareas are unambiguously defined. The goal of this paper is to motivate research which addresses the challenges currently faced in the industrial sector with regard to service. For this purpose, we review existing definitions of industrial services and identify the services in scope as well as the scientific disciplines that can contribute. The main part of the paper is a list of relevant current and future challenges which have been encountered by the authors during their daily practice., Enterprise Modelling and Information Systems Architectures, Vol 11 (2016)

In this paper, we describe an approach to understanding data quality issues in field data used for the calculation of reliability metrics such as availability, reliability over time, or MTBF. The focus lies on data from sources such as maintenance management systems or warranty databases which contain information on failure times, failure modes for all units. We propose a hierarchy of data quality metrics which identify and assess key problems in the input data. The metrics are organized in such a way that they guide the data analyst to those problems with the most impact on the calculation and provide a prioritised action plan for the improvement of data quality. The metrics cover issues such as missing, wrong, implausible and inaccurate data. We use examples with real-world data to showcase our software prototype and to illustrate how the metrics have helped with data preparation. Using this way, analysts can reduce the amount of wrong conclusions drawn from the data to mistakes in the input values.

\(\it Problem:\) Bei der beidseitigen Leistenhernienversorgung männlicher Patienten mittels TEP-BLV wird eine mögliche Beeinträchtigung der Zeugungsfähigkeit diskutiert. \(\it Methode:\) 59 männliche Patienten mit beidseitiger Leistenhernie wurden operiert und retrospektiv (38) sowie prospektiv (21) über einen Zeitraum von je 18 Monaten untersucht (Parameter: Hodenvolumen und Durchblutung, Ejakulatvolumen und Spermienanzahl, Sexualhormonkonzentration von FSH, LH, Testosteron). Die Untersuchung erfolgte 3 Monate postoperativ, prospektiv zudem unmittelbar praeoperativ. \(\it Ergebnis:\) In der retrospektiven und prospektiven Gruppe fanden sich keine Hinweise für eine operationsbedingte Fertilitätsbeeinträchtigung des Kollektivs. \(\it Diskussion:\) Die hier genutzte standardisierte Operationstechnik stellt ein sicheres Verfahren in der beidseitigen Hernienversorgung beim Mann dar.
