Improving comprehension of process diagrams with Graphical highlightsGregor Jošt
, 2018, doktorska disertacija
Opis: The main purpose of business process diagrams is to facilitate the communication between the process-related stakeholders, which directly affects the decision-making. For this reason, they must be easy to understand. However, this is often challenging to achieve, since business process diagrams can become large and complex. This, in turn, can negatively affect their correctness and understandability. The goal of this doctoral thesis was to propose and investigate an approach that makes business process diagrams appear less complex, without changing the corresponding diagrammatic notation or the business process diagrams themselves. This was done by manipulating the opacity of graphical elements in order to emphasize the important parts of a business process diagram by lowlighting the irrelevant ones. The proposed solution, named Emphasis, implemented with opacity-based Graphical Highlight pattern, abbreviated as simply Graphical highlights, was subsequently applied to sample business process diagram, modeled in Business Process Model and Notation (BPMN). The analysis demonstrated that the structural complexity of the business process diagrams decreased when the proposed solution was applied. Afterwards, a Web application prototype was implemented, which supports the proposed set of Graphical highlights.
Furthermore, we empirically validated whether Graphical highlights positively impact cognitive effectiveness of business process diagrams, and if the users will find the prototype implementation useful. To this end, an experimental research, which included 85 participants, was conducted. The participants were randomly assigned in either the treatment group (Graphical highlights diagram representation approach), or the control group (conventional diagram representation approach). In accordance with the definition of cognitive effectiveness, speed, ease, and accuracy of answering 26 comprehension questions were observed, along with the perceived usefulness of the prototype. The results of the analysis demonstrated that participants who used Graphical highlights significantly outperformed those that used the conventional approach in all experiment's observations.
We can conclude that using Graphical highlights increases the cognitive effectiveness of business process diagrams, while the corresponding prototype implementation is perceived as being useful.

Characteristics of Austrian remedies against enforcement and a general analysis of their suitability for achieving the objectives of Brussels I recastBettina Nunner-Krautgasser
, 2015, izvirni znanstveni članek
Opis: Regulation No 1215/2012 (Brussels Ia or Brussels I Recast) was another big step forward towards the establishment of a genuine European judicial area. In the wake of the Brussels I Recast, two facts have rather soon become apparent: One, several well- known (or better: infamous) issues are sadly still unsolved. And two, some other issues have emerged. Because of the abolishment of the “exequatur procedure”, esp. the issue of remedies against enforcement, in both the Member State of origin as well as in the Member State of enforcement, has gained more importance again. Therefore this paper analysis the characteristics of Austrian remedies in enforcement and their suitability for achieving the objects of Brussels I Recast.
Ključne besede: Brussels I Recast, remedies in enforcement, cross- border enforcement, abolition of “exequatur”, Art. 46 Brussels I a Recast, grounds for refusal of the enforcement, implementation in the national system of remedies in enforcement

, 2016, samostojni znanstveni sestavek ali poglavje v monografski publikaciji
Opis: Environmental problems, material depletion, and high dependency on fossil fuels are core problems of logistics in the EU as well as globally. Therefore, numerous countries, in particular Member States of the EU, have ambitious goals for the increased use of renewables, increased energy efficiency, the reduction of greenhouse gas emissions, transition to sustainable transportation and similar changes. EU companies are, therefore, strongly committed to reducing their environmental impact, reducing the use of fossil fuels and becoming more sustainable. Logistics companies are no exception due to the impact of logistics processes, such as transportation and distribution that impact human health, ecosystem and air quality, climate changes (with noise, vibrations, fossil fuel related harmful emissions etc.), warehousing (especially with energy used for heating and cooling) and packaging (especially with the use of material). Therefore, the implementation of green logistics is necessary for the sustainable future of our planet. This chapter identifies how the idea of green logistics was developed and has evolved, analyses key problems for its implementation, and presents the current status of green logistics, including the best practices of green logistics implementation in selected organizations.

The impact of managers on successful ERP implementationFranc Ravnikar
, 2010, izvirni znanstveni članek
Opis: Lately, Enterprise Resource Planning (ERP) has been implemented in public organizations and organizations without competition in the marketplace. It is the ERP system that is almost as badly needed for the competitiveness and success of those organizations in the marketplace. The main reason lies in the fact that operating costs have to be reduced and the optimization of business processes is an option which nowadays is normally implemented together with new ERP. The success rate of ERP implementation remains very low with up to a 90% failure rate, as it is quoted in a lot of researches. Critical success factors (CSF) which influence successful ERP implementation are identical in all organizations. The main goal of this research is to find out the managers' impact on the critical success factors and thus their impact on the successful ERP implementation. Top management support is the most important critical success factor for successful ERP implementation, regardless of the fact whether the organization is on the market or not.

Opis: Building information modelling (BIM) may currently be considered the fastest developing concept in the field of construction management, aiming to become a global standard. Although the roots of the concept date back to the mid-1970s, some original expectations are still missing from its implementation. There has been a time gap between its theoretical and practical implementations. While the simultaneous development of information technologies is one reason for the implementation delay, other reasons remain unclear. This paper analyzes the gaps between theoretical and practical BIM application, as well as the legislation regarding BIM implementation in four countries (in alphabetical order: Croatia, the Czech Republic, Germany, and Slovenia). The paper additionally presents a survey of current practical BIM applications as well as general and theoretical feedback from construction projects that implemented BIM.

, Armand Faganel
, 2009, izvirni znanstveni članek
Opis: Customer relationship management - CRM implementations increased rapidly in Slovenia in the last few years, following the trends elsewhere. Studies reporting how the implementation project goes on before, between and after the implementation are scarce. We offer a thorough case study analysis of the CRM implementation with a positive outcome in a Slovene service company. Case study demonstrates that CRM implementation is a holistic and complex concept, which means that it is not merely an integration of new information technology, but everything that happens around the business processes changes. We recommend that the company has already established a process approach and the orientation toward customers. Study showed the need for efficient leadership, acquirement of resources and CRM strategy implementation control; trust to the software solution shouldn't be self-understood. Through implemented analytical CRM company can improve the relationship with customers, achieve larger information sharing between employees and accept better strategic decisions.

Usage of agile SCRUM methodology on configuration management applicationŽeljko Stanojević
, 2017, magistrsko delo/naloga
Opis: The purpose of the master thesis is to research and determine how to successfully manage a project using agile methodology Scrum. Scrum methodology will be used to improve the functionality of existing internally developed software solutions.
Scrum, being an agile methodology, is an alternative approach to the traditional waterfall methodology, and is typically used in software development. Agile methodologies help teams respond to a project’s unpredictability by using incremental, iterative way of work known as sprints.
The first part of the master’s thesis presents a problem, defines goals and methods used, and the necessary tools required to achieve the objectives.
The following part of the thesis presents the foundations of agile methodologies and describes the used methodology – Scrum - in detail.
In the practical part, the thesis presents the existing software solution and opportunities for its improvement. We use Scrum for upgrading existing application, including all the attributes of the mentioned methodology, from team design to artifacts and events.
The thesis also presents a renewed application in detail. In conclusion, by using the SWOT analysis we observe suitability for use of the Scrum methodology in the case of renewal of application and propose further changes to improve the application.

A primary human critical success factors model for the ERP system implementationAleksander Jenko
, Matjaž Roblek
, 2016, izvirni znanstveni članek
Opis: Background and Purpose: Many researchers have investigated various Critical success factors (CSFs) and the different causes of ERP implementation project failures. Despite a detailed literature preview, we were unable to find an appropriate research with a comprehensive overview of the true causes behind CSFs, observed from a human factors perspective. The objective of this research was therefore to develop and evaluate the Primary human factors (PHFs) model and to confirm the significant impact of PHFs on traditional CSFs and on the project success.
Design/Methodology/Approach: The comprehensive PHFs research model was developed and examined in empirical quantitative research with the use of available literature and the application of the Root cause analysis. A survey was conducted in various Slovenian organisations in different branches that had previously implemented the ERP system SAP. The model was verified on a sample of 21 experts from 18 organisations.
Results: The results show that the PHFs have a significant positive impact on the ERP implementation project success, but only the Competence and Team composition factors are significant linear predictors in an adapted regression model and contribute significantly in predicting project success. These results therefore confirm both proposed hypotheses and the adapted regression model.
Conclusion: This study improves the understanding of PHFs and confirms that they have a significant impact on traditional CSFs and the ERP implementation project success. The proposed PHFs model offers project managers and other stakeholders an effective risk assessment of CSFs and is leading the way to human oriented model of ERP implementations.

Business Intelligence system implementation at a health services providerUroš Malnaršič
, 2016, diplomsko delo
Opis: Business Intelligence (BI) is important to any company wanting not only to improve their processes and data quality, but above all their decision-making. The scale of BI systems implementations ranges from small to large. A rule of thumb is that it is the end users who define the scope of an implemented BI solution. After all, a BI project and solution can only be considered successful if they are used after completion.
There are several vendors of BI tools and solutions who share a basic foundation, yet whose implemented solutions differ in approach, flexibility and enhancement options. However, they all share the challenges faced by the BI industry since its inception, from Big Data to Predictive Analytics and Data Discovery, to name just a few.
In this study, an American vendor of BI tools and solutions, Information Builders, is examined. They have been a market player for forty years and have influenced the development of this industry both directly and indirectly.
The main part of the research comprises a case study of a BI system implementation at a health services provider in the Netherlands. By providing insight into a BI implementation project and its successes and failures, the study is able to analyse every aspect of its management and consider the possibilities and functionalities offered by Information Builders’ WebFOCUS platform to solution developers and end users. Furthermore, the study analyses influence of Information Builders’ best practice on the success of the BI implementation project.
