A framework and tool to manage Cloud Computing service quality

Cloud Computing has generated considerable interest in both companies specialized in Information and Communication Technology and business context in general. The Sourcing Capability Maturity Model for service (e-SCM) is a capability model for offshore outsourcing services between clients and providers that offers appropriate strategies to enhance Cloud Computing implementation. It intends to achieve the required quality of service and develop an effective working relationship between clients and providers. Moreover, quality evaluation framework is a framework to control the quality of any product and/or process. It offers a tool support that can generate software artifacts to manage any type of product and service efficiently and effectively. Thus, the aim of this paper was to make this framework and tool support available to manage Cloud Computing service quality between clients and providers by means of e-SCM.Ministerio de Ciencia e Innovación TIN2013-46928-C3-3-RJunta de Andalucía TIC-578

The OpenESEA Modeling Language and Tool for Ethical, Social, and Environmental Accounting

Assessing business operations’ ethical, social, and environmental impacts is a key practice for establishing sustainable development. There is a multitude of methods that describes how to perform such assessments. Often these methods are supported by an ICT tool. In most cases, the tools are developed to support a single method only and do not allow any tailoring. Therefore, they are rigid and inflexible. In this article, we present a novel model-driven approach for alleviating managerial issues that arise as a consequence of the complex landscape of ethical, social, and environmental accounting methods and tools. We have developed an open-source, model-driven tool, called openESEA. OpenESEA parses and interprets textual models, that are specified according to a domain-specific language (DSL). We have performed another iteration of the DSL engineering process, which is in line with the design science paradigm. We have validated the new DSL version by means of a user study. As a result, we present a new version of the openESEA modeling language and interpreter. The results of the user study with regards to performance, perceived usefulness, and perceived ease of use of modeling language are encouraging and provide us with a basis to continue developing new versions with more functionalities. The contributions of this work include a new version of the modeling language, a new version of the interpreter, knowledge surrounding the development of these artifacts, and a protocol for evaluating the quality of textual DSLs. The modeling language and interpreter are relevant for sustainability practitioners and consultants since our tool support has the potential to reduce redundancy in ethical, social, and environmental accounting. Our work is valuable to researchers that aim to assess and reduce the complexity of their modeling languages

The Measurement of Quality of Semantic Standards: the Application of a Quality Model on the SETU standard for eGovernment

eGovernment interoperability should be dealt with using high-quality standards. A quality model for standards is presented based on knowledge from the software engineering domain. In the tradition of action research the model is used on the SETU standard, a standard that is mandatory in the public sector of the Netherlands in order to achieve eGovernment interoperability. This results in improvement suggestions for the SETU standards, just as improvement suggestions for the quality model have been identified. Most importantly it shows that a quality model can be used for several purposes, including selecting standards for eGovernment interoperability

A model‐based solution for process modeling in practice environments: PLM4BS

Today's world economic situation is ruled by issues such as reducing cost, improving quality, maximizing profit, and improving and optimizing processes at organizations. In this context, business process management can be an essential strategy, but it is not usually consolidated at software organizations because software process properties involve a complex business process management application on software lifecycle. Consequently, software organizations often focus on Software Process Modeling (SPM), and each involved role performs process execution and orchestration independently and manually. This fact makes software processes maintenance, monitoring, and measurement become difficult tasks. This paper proposes a model‐based approach for SPM taking into account concepts related to process execution, orchestration, and monitoring. It is framed into a model‐driven engineering‐based and toolbased framework: Process Lifecycle Management for Business Software (PLM4BS). We present a SPM metamodel and its concrete syntax (through Unified Modeling Language profiles) that lays the foundation for extending PLM4BS. Its underlying metamodel allows managing processes automatically. Furthermore, PLM4BS improves current state‐of‐the‐art proposals in 6 dimensions: expressiveness, understandability, granularity, measurability, orchestrability, and business variables and rules. Also, PLM4BS has been evaluated in a multiple‐case study, in which the 6 mentioned dimensions were already validated.Ministerio de Economía y Competitividad TIN2016‐76956‐C3‐2‐RMinisterio de Economía y Competitividad TIN2015‐71938‐RED

Framework for a business interoperability quotient measurement model

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova da Lisboa para obtenção do grau de Mestre em Engenharia e Gestão Industrial (MEGI)Over the last decade the context of Interoperability has been changing rapidly. It has been expanding from the largely technically focused area of Information Systems towards Business Processes and Business Semantics. However, there exists a need for more comprehensive ways to define business interoperability and enable its performance measurement as a first step towards improvement of interoperability conditions between collaborating entities. Through extensive literature reviews and analysis of European Research initiatives in this area, this dissertation presents the State of the Art in Business Interoperability. The objective of this dissertation is to develop a model that closely captures the factors that are responsible for Business Interoperability in the context of Collaborative Business Processes. This Business Interoperability Quotient Measurement Model (BIQMM), developed in this dissertation uses an interdisciplinary approach to capture the key elements responsible for collaboration performance. Through the quantification of the relevance of each element to the particular collaboration scenario in question, this model enables a quantitative analysis of Business Interoperability, so that an overall interoperability score can be arrived at for enhanced performance measurements.Finally, the BIQMM is applied to a business case involving Innovayt and LM Glassfiber to demonstrate its applicability to different collaboration scenarios

A Multi-dimensional Framework for Characterizing Domain Specific Languages

The paper presents a questionnaire to assess Domain Specific Languages based on a multi-dimensional framework for characterizing languages. An issue is whether and how to distinguish between characteristics of domain-specific and general purpose languages. We discuss how to emphasize dimensions that are particularly important for domain-specific languages such as being formal, yet transparent as well as integrable with other languages. We consider hazards and potentials of the approach.A Multi-dimensional Framework for Characterizing Domain Specific Language

Development of a web application for management of learning styles

Information and Communication Technologies (ICT) permit the innovation of teaching and learning processes. ICT allow teachers to create or select and adjust contents that take advantage of the digital environment and interaction between peers. Teaching methodologies and strategies should be adjusted to the learning styles of students, offering them, in turn, the possibility to reflect about the way in which they might learn better. This article introduces a work of creation and validation of a web-based application, which aims to enhance the Management of Learning Styles (MLS) on the part of students and teachers, based on Felder-Soloman's Index of Learning Styles Questionnaire (ILS) and Honey-Mumford's Learning Styles Questionnaire (LSQ). The prototype has been validated and the results suggest its applicability and the relevance of the information this tool is capable of obtaining - reports on the learning styles profiles by student, teacher and class - with the objective of supporting them in the selection of strategies to improve teaching and learning, developing at the same time skills which will allow them to learn throughout their lives

A socio-cognitive and computational model for decision making and user modelling in social phishing

Systems software quality, and system security in particular, is often compromised by phishing attacks. The latter were relatively easy to detect through phishing content filters, in the past. However, it has been increasingly difficult to stop more recent and sophisticated social phishing attacks. To protect the citizens from new types of phishing attacks, software quality engineers need to provide equally sophisticating preventive technology that models people’s reactions. The authors considered the behaviour of people on the Internet from a socio-cognitive perspective and deduced who could be more prone to be spoofed by social phishing techniques. The authors herein propose a computational and interdisciplinary metamodelling methodology, which can assist in capturing and understanding people’s interactive behaviour when they are online. Online behaviour can reveal Internet users’ knowledge, information, and beliefs in a given social context; these could also constitute significant factors for trust in social phishing circumstances which, in turn, can provide valuable insights and decision making meta-knowledge for recognition of potential victims of phishers. The proposed modelling approach is illustrated and explained using real-life phishing cases. This meta-model can i) help social computing and phishing researchers to understand users’ trust decisions from a socio-cognitive perspective, and ii) open ways to integrate artificial intelligence design techniques within software quality management practices in order to protect citizens from being spoofed by social phishing attacks. Thus, this software design quality approach will increase system security as a proactive maintenance strategy
