“…The experiments conducted during the second validation were designed considering the FUEML framework [75] and the Principles of Survey Research [76][77][78][79][80][81]. Since the overall objective of the validation was to establish if our MBM allowed the construction and understanding of an NCB, we defined the objective of the experiments in terms of two hypotheses: Hypothesis 1.…”

The business is an abstraction of the way in which value is created and delivered. The concrete representation is the business model, expressed by a group of artifacts built with different languages. It serves to describe, explain, analyze, design, and evaluate the business. The set of concepts, construction rules, artifacts, and languages required to express it, are defined by a Meta-Business Model (MBM). Multiple authors have proposed different MBMs, each one with a specific motivation and objective. Some of these MBMs are widely recognized and have been applied in contexts like innovation and entrepreneurship. Due to new challenges, such as sustainability, being faced by businesses and given new ways of producing and delivering value, like the sharing economy, Novel Complex Businesses (NCBs) are emerging. NCBs are businesses characterized by circular structures made out of numerous inter-related components, and by creating value out of the product/service schema. While existing MBMs fulfill certain purposes, they do not have the expressiveness required to describe NCBs precisely enough to describe and analyze them. This paper introduces an MBM with the concepts, construction rules, and graphical notation needed to represent NCBs. We also illustrate an NCB and present the results of the validation for our MBM.

“…in [26] in this regard. User satisfaction means the degree to which user needs are satisfied in the usage [27] (it is defined similarly in different works of literature such as [26, 28]). In three experiments, potential users of the developed language participated in the training, exercises, and a user perception questionnaire for the analysis of (i) how much effectiveness is achieved compared with conventional language, (ii) how much satisfaction the users perceive during usage of the language; and (iii) assessed feedback to elaborate the developed language coming up with the users’ perspective.…”

“…Effectiveness means the possibility of accomplishing a successful task and that a user should be able to comprehend and create artefacts in the (modelling) language to an acceptable degree, as summarised by Schalles et al. in [26] in this regard. User satisfaction means the degree to which user needs are satisfied in the usage [27] (it is defined similarly in different works of literature such as [26, 28]).…”

The dependability characteristic of the control software of manufacturing systems is highlighted more than before, going through repeated changes to cope with various and varying requirements. Formal methods are researched to be applied to automation system engineering to obtain a more effective and efficient quality assurance. One of the approaches, a formal specification language named Generalised Test Tables has been developed with the aim of intuitiveness and accessibility for automation application developers. The result of the experiments conducted to assess the usability of this language is presented here. Focussing on evaluating effectiveness and user satisfaction, three paper-based experiments have been conducted with students at the bachelor and master level. The evaluation results point to positive usability in both comparative effectiveness to conventional language, that is, Petri Nets, and subjective perception of user satisfaction.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
