  • MILAGE LEARN+: A mobile learning app to aid the students in the study of organic chemistry
    Publication . Fonseca, Custódia; Zacarias, Marielba; Figueiredo, Mauro
    Interactive learning is one of the approaches that is very important to explore in higher education. Chemistry students own smartphones, laptops, and tablets and could use appropriate apps to complement traditional forms of learning. Here we introduce a new app, MILAGE LEARN+, which integrates several teaching strategies, such as mobile learning, autonomous learning, peer review, blended learning, and gamification. These strategies were evaluated by the student users through an electronic survey form containing 15 statements with responses graded on a Likert-type scale. Students rate the usage of novel teaching/learning strategies in the MILAGE LEARN+ app as something very positive. There is a positive correlation between the relative grades obtained using MILAGE LEARN+ and the final exam grades. Thus, in this experience, students with better results in MILAGE LEARN+ also had better results in the final exam.
  • Using augmented reality for learning naval operations
    Publication . Correia, Anacleto; Goncalves, Antonio; Zacarias, Marielba; Rocha, A.; Pereira, R. P.
    Augmented reality (AR) is a technology that extends the perception of human reality by allowing, for example, inserting virtual objects in real environments. With augmented reality, learning can be more effective with graphics and interactivity in the manipulation of content. With this work, we intend to apply the AR technology in a process of developing a solution in learning context. For this purpose, different types of devices were analyzed in order to select the type of equipment with better characteristics for use in teaching/learning solutions. An agile development process was tailored to be used in the development of AR applications. The process was then instantiated in the development of an AR solution for learning purposes of ships' maneuvers in formations in the context of naval operations. The effectiveness of the AR solution was then validated through statistical tests of data collected from a survey to a sample of users.
  • BPPAM tool: A business process framework
    Publication . Martins, Paula Ventura; Zacarias, M.
    Current business process modeling methodologies offer little guidance regarding how to discover and maintain business process models aligned with their actual execution. We argue that business processes should emerge and evolve collaboratively within an organization. In this article we present a business process and practice authoring tool based on our vision for business process improvement. (C) 2016 The Authors. Published by Elsevier RV.
  • BAM: business alignment methodology
    Publication . Zacarias, Marielba; Martins, Paula Ventura
    Information flows across the organization are complex and procedures employed to understand, share and control organizational knowledge and experiences should be properly supported by collaborative environments. Nevertheless, few collaborative methodologies had been proposed to describe and evolve business processes. In the future, business processes models should be the result of cross-team and cross-departmental collaboration, with involved business people sharing their personal knowledge and formalizing it. This paper focuses on a methodology for business process discovery and the importance to integrate local information into coherent and sound process definitions. Business Alignment Methodology (BAM) is a methodology that provides guidance about how organizational practices and knowledge are gathered to contribute for business process improvement against current BPM approaches.
  • An agile business process improvement methodology
    Publication . Martins, Paula Ventura; Zacarias, Marielba; CruzCunha, MM; Varajao, JEQ; Rijo, R; Martinho, R; Peppard, J; SanCristobal, JR; Monguet, J
    Adoption of business process improvement strategies are now a concern of most organisations. Organisations are still facing challenges and finding transient solutions to immediate problems. The misalignment between IT solutions and organisational aspects evolves across space and time showing discrepancies. Unfortunately, existing business process approaches are not according with continuous business process improvement involving business stakeholders. Considering this limitation in well-known Business Process (BP) methodologies, this paper presents a comparative study of some approaches and introduces agility in the Business Process and Practice Alignment Methodology (BPPAM). Our intention is to present observed problems in existing approaches and introduce agility in our proposal to address features, like the alignment between daily work practices and business process descriptions, in a simple and agile way.

  • Collaborative business process discovery: method and case study
    Publication . Martins, Paula Ventura; Zacarias, M.; Castela, Nuno; Dias, Paulo
    Information flows across the organization are complex and procedures employed to understand, share and control organizational knowledge and experiences should be properly supported by collaborative environments. Nevertheless, few collaborative methodologies had been proposed to describe and evolve business processes. Existing tools don’t provide the right methods for business processes discovery, modeling, monitoring and improvement. In the future, business processes models should be the result of cross-team and cross-departmental collaboration, with involved business people sharing their personal knowledge and formalizing it. This paper focuses on case study applying a collaborative process discovery method. Business Alignment Methodology (BAM) is a methodology that provides guidance about how organizational practices and knowledge are gathered to contribute for business process improvement against current BPM approaches.
  • An agile business process and practice meta-model
    Publication . Zacarias, Marielba; Martins, Paula Ventura; Gonçalves, António; CruzCunha, M. M.; Varajao, J. E. Q.; Rijo, R.; Martinho, R.; Peppard, J.; SanCristobal, J. R.; Monguet, J.
    Business Process Management (BPM) encompasses the discovery, modelling, monitoring, analysis and improvement of business processes. Limitations of traditional BPM approaches in addressing changes in business requirements have resulted in a number of agile BPM approaches that seek to accelerate the redesign of business process models. Meta-models are a key BPM feature that reduce the ambiguity of business process models. This paper describes a meta-model supporting the agile version of the Business Process and Practice Alignment Methodology (BPPAM) for business process improvement, which captures process information from actual work practices. The ability of the meta-model to achieve business process agility is discussed and compared with other agile meta-models, based on definitions of business process flexibility and agility found in the literature.

  • Collaborative method to maintain business process models updated
    Publication . Castela, Nuno; Dias, Paulo; Zacarias, Marielba; Tribolet, Jose M.
    Business process models are often forgotten after their creation and its representation is not usually updated. This appears to be negative as processes evolve over time. This paper discusses the issue of business process models maintenance through the definition of a collaborative method that creates interaction contexts enabling business actors to discuss about business processes, sharing business knowledge. The collaboration method extends the discussion about existing process representations to all stakeholders promoting their update. This collaborative method contributes to improve business process models, allowing updates based in change proposals and discussions, using a groupware tool that was developed. Four case studies were developed in real organizational environment. We came to the conclusion that the defined method and the developed tool can help organizations to maintain a business process model updated based on the inputs and consequent discussions taken by the organizational actors who participate in the processes.
  • Business process and practice alignment meta-model
    Publication . Martins, Paula Ventura; Zacarias, M.; Cruz Cunha, M. M.; Varajao, J.; Rijo, R.; Martinho, R.; Schubert, P.; Boonstra, A.; Correia, R.; Berler, R.
    Business Process Modelling (BPM) is one of the most important phases of information system design. Business Process meta-models allow capturing informational and behavioural aspects of business processes. Unfortunately, standard business process meta-modelling approaches, such as the Business Process Model and Notation (BPMN) Meta-model, Quality-Oriented Business Process Meta-Model (QOBPM) and Transactional Meta-Model for Business Process (TMBP) focus just on process description, providing different business process models. According to these meta-modelling approaches, it is not possible to compare and identify related daily practices in order to improve business process models. This lack of information recognizes that further research in Business Process (BP) meta-model is needed to reflect the evolution/change on software processes. Considering this limitation in BP meta-modelling, this paper presents a comparative study of the most recognized business process meta-models approaches and introduces a new BP meta-model designed by Business Process and Practice Alignment Meta-model (BPPAMeta-model). Our intention is to present observed problems in existing approaches and propose a business process meta-model that addresses features related to the alignment between daily work practices and business process descriptions.
