Responsible Software Engineering 139 and associated documentation of an information processing system. . . . (It) is an intellectual creation that is independentof themediumonwhich it is recorded.” Software exists in many types and variants and there is no widely adopted software taxonomy. Rather, there exist surveys for specific fields of software applications or software development tools such as in software-defined networks [7], foruser interfaces [8]or for softwaredocumentation[9]. Although it is apparently hard to grasp characteristics of software in general, there is a long-lasting and still growing understanding of how software quality is constituted. The ISO 25010 provides an updated set of software quality require- ments [10] compared to ISO 9126 or other previously established software quality models, like theonebyBoehmetal. [11],FURPS[12],byIEEE[13],Dromey[14] orQMOOD[15]. Still, since software technologies evolve, the understanding of software quality needs to evolve as well. For example, software usability addresses the ease of use of a software [16].For specified consumers, it seeks to improve their effectiveness, efficiency and satisfaction in achieving their objectives by the given context of use and the usagescenarios fora software. Another example is the growing importanceof data (as software in itself and as a software artefact in use) in big data, Internet of Things or artificial intelligence applications [17]. Data quality assessment [18] aims at deriving objective data qualitymetrics that resemblealso subjectiveperceptionsofdata.
