Analysing the cognitive effectiveness of the WebML visual notation
(2017-02-17) Granada, David; Vara, Juan M.; Brambilla, Marco; Bollati, Verónica; Marcos, Esperanza
WebML is a domain-specific language used to design complex data-intensive Web applications at a conceptual level. As WebML was devised to support design tasks, the need to define a visual notation for the language was identified from the very beginning. Each WebML element is consequently associated with a separate graphical symbol which was mainly defined with the idea of providing simple and expressive modelling artefacts rather than by adopting a rigorous scientific approach. As a result, the graphical models defined with WebML may sometimes prevent proper communication from taking place between the various stake-holders. In fact, this is a common issue for most of the existing model-based proposals that have emerged during the last few years under the umbrella of model-driven engineering. In order to illustrate this issue and foster in using a scientific basis to design, evaluate, improve and compare visual notations, this paper analyses WebML according to a set of solid principles, based on the theoretical and empirical evidence concerning the cognitive effectiveness of visual notations. As a result, we have identified a set of possible improvements, some of which have been verified by an empirical study. Furthermore, a number of findings, experiences and lessons learnt on the assessment of visual notations are presented.

Leveraging creativity in requirements elicitation within agile software development: A systematic literature review
(2019-11-01) Aldave, Ainhoa; Vara, Juan M.; Granada, David; Marcos, Esperanza
Agile approaches tend to focus solely on scoping and simplicity rather than on problem solving and discovery. This hampers the development of innovative solutions. Additionally, little has been said about how to capture and represent the real user needs. To fill this gap, some authors argue in favor of the application of “Creative thinking” for requirements elicitation within agile software development. This synergy between creativeness and agility has arisen as a new means of bringing innovation and flexibility to increasingly demanding software. The aim of the present study is therefore to employ a systematic review to investigate the state-of-the-art of those approaches that leverage creativity in requirements elicitation within Agile Software Development, as well as the benefits, limitations and strength of evidence of these approaches. The review was carried out by following the guidelines proposed by Dr. Kitchenham. The search strategy identified 1451 studies, 17 of which were eventually classified as primary studies. The selected studies contained 13 different and unique proposals. These approaches provide evidence that enhanced creativity in requirements elicitation can be successfully implemented in real software projects. We specifically observed that projects related to user interface development, such as those for mobile or web applications, are good candidates for the use of these approaches. We have also found that agile methodologies such as Scrum, Extreme Programming or methodologies based on rapid modelling are preferred when introducing creativity into requirements elicitation. Despite this being a new research field, there is a mixture of techniques, tools and processes that have already been and are currently being successfully tested in industry. Finally, we have found that, although creativity is an important ingredient with which to bring about innovation, it is not always sufficient to generate new requirements because this needs to be followed by user engagement and a specific context in which proper conditions, such as flexibility, time or resources, have to be met.
Model-Based Tool Support for Service Design
(Springer, 2020-04-17) Pérez-Blanco, Francisco Javier; Vara, Juan Manuel; Gómez-Macías, Cristian; De Castro, Valeria; Marcos, Esperanza
This paper introduces a modelling environment for service design that currently supports 5 different notations (Business Model Canvas, e3value, Service Blueprint, Process Chain Network and BPMN). Besides, the tool supports the generation of partial views of models based on a particular notation from models made with another one, along with the corresponding relations model.
Training New Professionals in Service Engineering: Towards a Transdisciplinary Curriculum for Sustainable Businesses
(MDPI, 2020-10-08) Marcos, Esperanza; De Castro, Valeria; Martín-Peña, Mª Luz; Vara, Juan Manuel
The service sector provides employment for more than 70% of the active population in developed countries, in areas as varied as tourism, commerce, logistics, finances, services, and personnel, amongst others. Despite the fact that society increasingly needs more professionals who are oriented towards this sector, there are hardly any specific plans that will provide them with appropriate training. The appearance of service science, management, and engineering (SSME) has led to a significant advance as regards understanding the skills required by a service professional. It is a transdisciplinary field that integrates aspects of business management, along with information and communication technologies and engineering, and social sciences, in addition to providing the foundations for the growth of sustainable business. This paper presents a curriculum for the training of professionals in service engineering, which has been designed and taught at a Spanish public university. This curriculum, which the university created in collaboration with SSME experts and service sector companies, stands out for two reasons: the transdisciplinary approach employed, which is one of the features of this emerging and integrative knowledge discipline, and the fact that it is providing a response to the need for higher education curricula for sustainable business development. The paper describes the method followed to create the curriculum for the Bachelor’s Degree in Service Engineering, a comparative study with other related degrees, and the results of the deployment of the degree in terms of employability.
