The acquisition of knowledge takes place through facts and statements based on the subject matter and by repetition in exercises. Providing game elements in university teaching, students should be more motivated and deal with the teaching content more intensively. The knowledge imparted is to be prepared more attractively for the students and a greater bond to the respective module is to be built up. Game-typical elements can efficiently link the individual sub-processes of learning with each other and thus maximize a student's performance, knowledge level and motivation. Due to the Covid19 pandemic and the ever-advancing technology development, digital teaching and learning have become essential components of university teaching in the long run. Because quality management is a field that is closely related to practice, the focus is not only on teaching theoretical knowledge but also on practical relevance. The Chair of Quality Management offers the module Project Management every summer semester. The learning objective of the module is to enable students to plan projects and organize their implementation. The module Project Management consists of a lecture, a seminar, and a semester project. In the lecture, students are taught the basics of project management. In the seminar, students learn to select and apply project management methods for different problems. Practical exercises are supported by media and software demonstrations. In the semester project, students get together in groups and plan a project during the semester. The project is intended to help students practically implement the knowledge they have acquired in lectures and seminars. The topics are provided by the chair's corporate partners. To increase the realism of the projects, the handing out of an event card is linked to the interim deadlines. The event card implies an adjustment of already planned resources, activities and/or funds. To optimally adapt the gamification elements for the module, a target group analysis was first conducted as part of the research work. Based on the findings, an action plan was created on how the gamification approach could be transferred into the teaching concept of the module. After implementation, the module was examined further in the course of a teaching evaluation and a survey of the participating students. The main goal of the investigation was to find out to what extent game-typical elements promote the learning process and how practical projects support the learning process. On the one hand, the survey confirmed the promotion of motivation and the learning process by means of game-typical elements among the students. The results show that the creative and diverse way of conveying the learning material is accepted by the students. On the other hand, the study showed that too many of these elements can have a negative effect and a possible saturation effect occurs. Furthermore, the authenticity of the module or the chair may decrease. The results and knowledge from the research work flow into the adjustments of the module and are to be transferred to further modules of the chair in the future.

Thus, virtual collaboration has continuously gained in importance and the associated change in work organization is realized in virtually collaborating teams. In particular, the communication that takes place under these conditions differs significantly from traditional face-to-face communication and plays a central role in virtual team collaboration. The challenges and opportunities that arise in this context were investigated in this study. The study focuses on identifying the challenges employees face at the communication level in their everyday work. To this end, opinion interviews were conducted with employees of virtually collaborating teams. Based on the identified challenges, a survey was carried out to initiate the analysis based on (quantitative) data collection. After data cleaning, a sample of 291 participants could be collected. From the results obtained, potential improvements for communication, both for the management positions as well as the employees of virtually collaborating teams were derived. The research confirmed that the communication effort in virtual teamwork is higher than in real teamwork. Furthermore, virtual communication has a significant influence on the factors team identification, miscommunication and the decision-making processes in the team. Other findings of the study are that individuals who work only in face-to-face teams are more skeptical of virtual collaboration. In contrast, individuals who work exclusively virtually are more open to virtual and face-to-face collaboration. The results suggest there are more challenges when comparing virtual to face-to-face communication. In addition to the broader findings, it can be seen that the increasingly digitized world of work impacts communication and poses challenges for virtually collaborating teams. In addition to media competence, it is additionally important in this context that individual team members have team- and technology-related skills. In addition to these prerequisites, virtually collaborating team members should be prepared for and continuously supported in virtual collaboration and virtual communication through training, workshops and courses. This can be counteracted by increased communication, soliciting feedback, and face-to-face meetings. The research suggests that transparent and traceable communication and collaboration processes should be implemented in practice. KW - Virtual teamwork, collaboration, new work.

Especially by the use of Quality management tools regarding spreadsheets and statistics software. Therefore video tutorials, personal support and written instructions, as aids, are compared with and without time pressure. Methodology/Approach: Students of the quality management class participated in two tests in order to capture user behavior. In the first part the students (n = 56) were asked about their user behavior regarding aids after a project that lasted several months. In the second part the students (n = 40) were given two aids and captured which aids they are using. The duration period and the quality of the results were also documented. At the end of both tests, the students were asked about their future favorite aids. Findings: The first test revealed that 73% of the students used the video tutorial as an aid for their work. In future situations the students would work with written instructions, as long as there is no time pressure. If time limitation is a factor, they would rather work with video tutorials again. The second test confirmed that using video tutorials allowed for a shorter duration period. 48% were using the video tutorial while 38% used the written instruction. The suitability rating of the aids as well as the quality of the result did not differ. In future situations, the students would work again with video tutorials with or without time pressure. Research Limitation/implication: The usage of video tutorials, personal support and written instructions for the application of Quality management tools with the use of appropriate software has been examined. The results do not show conclusions about the extent to which the aids are used for the mediation of complex issues. Follow-up studies are required for this purpose. Originality/Value of paper: Among these three aids with regard to time pressure, video tutorials as well as the personal support seem to be the most efficient. If time pressure was applied to the test setting, the video tutorial was preferred. In the considered setting the use of video tutorials is recommended.

To achieve this, 186 possible causes of risk were analyzed and the five most critical risks were discussed in detail. Four significant risk factors were identified in the construction process. The fifth risk relates to the shielding gas flow. This is only one influencing factor among the welding parameters, which have strong interactions with each other. Therefore, their relationships should be analyzed on the basis of numerous tests.
