Process Mining for Six Sigma
Process mining offers a set of techniques for gaining data-based insights into business processes from event logs. The literature acknowledges the potential benefits of using process mining techniques in Six Sigma-based process improvement initiatives. However, a guideline that is explicitly dedicated on how process mining can be systematically used in Six Sigma initiatives is lacking. To address this gap, the Process Mining for Six Sigma (PMSS) guideline has been developed to support organizations in systematically using process mining techniques aligned with the DMAIC (Define-Measure-Analyze-Improve-Control) model of Six Sigma. Following a design science research methodology, PMSS and its tool support have been developed iteratively in close collaboration with experts in Six Sigma and process mining, and evaluated by means of focus groups, demonstrations and interviews with industry experts. The results of the evaluations indicate that PMSS is useful as a guideline to support Six Sigma-based process improvement activities. It offers a structured guideline for practitioners by extending the DMAIC-based standard operating procedure. PMSS can help increasing the efficiency and effectiveness of Six Sigma-based process improving efforts. This work extends the body of knowledge in the fields of process mining and Six Sigma, and helps closing the gap between them. Hence, it contributes to the broad field of quality management
Towards an Entropy-based Analysis of Log Variability
Rules, decisions, and workflows are intertwined components depicting the overall process. So far imperative workflow modelling languages have played the major role for the description and analysis of business processes. Despite their undoubted efficacy in representing sequential executions, they hide circumstantial information leading to the enactment of activities, and obscure the rationale behind the verification of requirements, dependencies, and goals. This workshop aimed at providing a platform for the discussion and introduction of new ideas related to the development of a holistic approach that encompasses all those aspects. The objective was to extend the reach of the business process management audience towards the decisions and rules community and increase the integration between different imperative, declarative and hybrid modelling perspectives. Out of the high-quality submitted manuscripts, three papers were accepted for publication, with an acceptance rate of 50%. They contributed to foster a fruitful discussion among the participants about the respective impact and the interplay of decision perspective and the process perspective
Assessing the relationship between bpm maturity and the success of organizations
Pinto, J., & dos Santos, V. D. (2020). Assessing the relationship between bpm maturity and the success of organizations. In R. Silhavy (Ed.), Applied Informatics and Cybernetics in Intelligent Systems: Proceedings of the 9th Computer Science On-line Conference, CSOC 2020 (pp. 108-126). (Advances in Intelligent Systems and Computing; Vol. 1226 AISC). Springer. https://doi.org/10.1007/978-3-030-51974-2_10For the past decades, organizations have been investing heavily in BPM projects in the hope of improving their competitive advantage in an increasingly complex environment. However, although it is believed that the higher the level of BPM maturity the greater the success of the organization, experience shows that this relationship is not always possible to prove. The purpose of this study is to help clarify the relationship between the level of BPM maturity and the success of an organization. This was done through the implementation of a case study-based research within a global company, focusing on the shared services organization. An analysis of the existing BPM maturity models and its level of coverage of BPM core areas was conducted to select the most suitable BPM maturity model to conduct the assessment of the current BPM maturity level. It was also established a framework to characterize the success of an organization. These two inputs, along with information gathered to understand implemented process improvements, were the basis for conducting the research. Results show a successful organization, with a high maturity level according to the BPM OMG maturity model, that has been investing in continually improving its processes with a strong focus on digital transformation. The identified benefits from a high level of BPM maturity, namely improved productivity, cost reduction, error & risk prevention, higher agility, employee upskilling and knowledge retention, were shown to have a positive influence in the majority of the dimensions used to characterize the success of the organization.authorsversionpublishe
The everpresent eta-problem: knowledge of all hidden sectors required
We argue that the eta-problem in supergravity inflation cannot be solved
without knowledge of the ground state of hidden sectors that are
gravitationally coupled to the inflaton. If the hidden sector breaks
supersymmetry independently, its fields cannot be stabilized during
cosmological evolution of the inflaton. We show that both the subsequent
dynamical mixing between sectors as well as the lightest mass of the hidden
sector are set by the scale of supersymmetry breaking in the hidden sector. The
true cosmological eta-parameter arises from a linear combination of the
lightest mode of the hidden sector with the inflaton. Generically, either the
true eta deviates considerably from the na\"ive eta implied by the inflaton
sector alone, or one has to consider a multifield model. Only if the lightest
mass in the hidden sector is much larger than the inflaton mass and if the
inflaton mass is much larger than the scale of hidden sector supersymmetry
breaking, is the effect of the hidden sector on the slow-roll dynamics of the
inflaton negligible.Comment: 27 pages, 6 figures; v2, published version, minor adjustments to the

Social Media, Gender and the Mediatisation of War: Exploring the German Armed Forcesâ Visual Representation of the Afghanistan Operation on Facebook
Studies on the mediatisation of war point to attempts of governments to regulate the visual perspective of their involvements in armed conflict â the most notable example being the practice of âembedded reportingâ in Iraq and Afghanistan. This paper focuses on a different strategy of visual meaning-making, namely, the publication of images on social media by armed forces themselves. Specifically, we argue that the mediatisation of war literature could profit from an increased engagement with feminist research, both within Critical Security/Critical Military Studies and within Science and Technology Studies that highlight the close connection between masculinity, technology and control. The article examines the German military mission in Afghanistan as represented on the German armed forcesâ official Facebook page. Germany constitutes an interesting, and largely neglected, case for the growing literature on the mediatisation of war: its strong antimilitarist political culture makes the representation of war particularly delicate. The paper examines specific representational patterns of Germanyâs involvement in Afghanistan and discusses the implications which arise from what is placed inside the frame of visibility and what remains out of its view
