Implementation and evaluation of the DAOM framework and support tool for designing blockchain decentralized applications

Inter-organizational collaboration is an important aspect of organizational operations. Traditional systems that support organizations in executing these collaborations are inefficient, not inter-operable and insecure. Novel functions provided by blockchain technology yields the potential for addressing problems that affect organizational collaborations by enabling tamper-proof, transparent, and secure systems for the exchange of information between organizations. Still, a proper approach for building blockchain-decentralized applications (DApps) that support inter-organizational collaborations is missing. The DAOM framework addresses this gap by providing a model-driven design approach for building DApps. This paper shows the development of the semantics of the DAOM framework, implementation of the support tool, and the evaluation of the DAOM framework and support tool. We conducted an evaluation to understand the usefulness of the DAOM framework in developing blockchain DApps and the effectiveness of the support tool in producing DAOM diagram models. The evaluation result shows that the framework is useful and applicable for developing DApps for inter-organizational collaborations. Furthermore, evaluation of the tool support shows that DApps can be modelled efficiently and correctly with the implemented enterprise-modelling software.

Model-Based Enterprise Continuous Improvement

The enterprise reengineering based on enterprise modelling is usually carried out within the framework of conventional projects. This leads to relatively long projects that are not compatible with a highly variable economic environment. The objective of the evolution management presented here is to use enterprise modelling and all the benefits it brings in a framework that allows for more continuous improvement than is generally observed. The proposed architecture is made up of three levels: a strategic level based on performance measurement, a tactical level that manages system migration and is based on enterprise models, and an operational level consisting of managing a portfolio of evolution projects. Together, these allow a shorter set of projects to be carried out, while remaining coherent and aligned with the company’s strategy. This approach puts enterprise modelling methods and continuous improvement/Lean management approaches into perspective, allowing complementarities and opening up interesting perspectives concerning enterprise re-engineering methods.

From Synchronous Face-to-Face Group Work to Asynchronous Individual Work: Pivoting an Enterprise Modelling Course for Teaching during a COVID-19 Lockdown

This paper outlines the challenges faced in a particular instance of an enterprise modelling (EM) course that lost the ability to have face-to-face interactions and describes a solution that proved to be at least equally effective and appreciated when moved online. The revised course design is primarily driven by exercise and assignment work, provides course content in a ‘piecemeal’ fashion, and relies almost exclusively on asynchronous interactions. This paper distils the solution into specific design features of the revised course as well as more general design principles that can be applied to other EM courses (and potentially beyond).
