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.

But how long? When are customers satisfied or dissatisfied with the waiting time and how should companies organize their waiting times? How do waiting experiences influence expectations and satisfactions? According to the assumptions of the expectation disconfirmation theory, customer satisfaction arises when the expectations of the service are fulfilled or exceeded. The aim of this study is to examine whether waiting experiences influence expectations and thus customer satisfaction. A further objective is to investigate the relationship between waiting experiences and acceptable waiting time. Methodology/Approach: 57 students of a course of the Brandenburg University of Technology took part in a 2-day trial. The actual purpose of the trial was not disclosed. Instead, students were given appointments to evaluate the quality of vehicle surfaces. After arriving to their appointments, they either waited 0 minutes, 5 minutes or 20 minutes alone in a room. On the second day, they waited the same length, longer or shorter under the same conditions. Students answered a questionnaire about their waiting satisfaction right after their waiting period. Supplementary questions distracted them from the actual aim of the questionnaire. Finally, the students evaluated the quality of vehicle surfaces on both days. The specified waiting times of 0 minutes, 5 minutes and 20 minutes were defined by the results of a pretest. The course was asked about its satisfaction with different waiting times. The times represent the transitions from very satisfied (0 minutes) with the waiting time, to satisfied (from 5 minutes) to dissatisfied (20 minutes). Findings: It can be stated that an acceptable waiting time describes a time which causes neither satisfaction, nor dissatisfaction. Already experienced waiting time affects expectations of a future waiting situation. Students who repeatedly waited 20 minutes were less dissatisfied with the waiting time than students who previously waited 0 or 5 minutes. Implication/Research Limitation: It is recommended to keep the waiting time constant. Strong variations in waiting time leads to particularly strong dissatisfaction of the customers and this can lead to avoiding the company. The study does not deal with strategies to reduce waiting time. For economic reasons, a target value of 0 minutes is not always useful. The acceptable waiting time can be used to determine the targeted waiting time. In addition, other factors such as the competitive situation should be taken into account. The results are based on an experiment. Therefore, the examination should be repeated in different waiting environments. Follow-up studies are required. Originality/Value of paper: The satisfaction of the customers regarding the waiting time is very important in order to bind customers to their company on a long-term basis. On the one hand the study gives advices for the organization of waiting times. On the other hand, the study gives an approach for the record of target values for waiting times. By using these advices, service companies can increase the waiting satisfaction of their customers and increase the long-term customer loyalty.}, language = {en} } @misc{RichHuelseWoll, author = {Rich, Beatrice Monique and H{\"u}lse, Max and Woll, Ralf}, title = {The first impression counts: View area investigations on vehicles}, series = {Proc. 22nd Quality Manage. and Organisational Develop. Int. Conf. on Quality and Service Sciences}, journal = {Proc. 22nd Quality Manage. and Organisational Develop. Int. Conf. on Quality and Service Sciences}, abstract = {Purpose: Based on a request from a automobile manufacturer, a feasibility study was carried out to compare the quality standards of different target groups with regard to defect perception. The following question developed as a result of the study: Do customers subdivide products (especially vehicles) into visual areas which they assign different relevance to the perception and the significance of defects? Automobile manufacturers classify their vehicles into viewing areas in order to assess the significance of defects during the product audit better. The study has shown that customers attach a different significance to the areas of view than it is specified in the company standard. A customer can perceive a seemingly insignificant defect in viewing area C (below the vehicle) as extremely significant. In order to investigate this in more detail, a visual field inspection on vehicles was conducted. Methodology/Approach: The study was carried out on 2 consecutive days. The test persons were asked to put themselves into the "real" situation that they pick up their purchased new car and see it for the first time. The test persons were shown imperfections on varnish samples. They were asked to imagine that the shown imperfections were on the respective vehicles and to evaluate them on the prepared questionnaires. Each test person filled out one questionnaire for each imperfection. The evaluation took place on a scale with the following breakdown: I would not notice (green)/ I would notice, but would not annoy me (yellow)/ I would notice and it would annoy me (orange)/ I would notice and I would complain about (pink). Findings: Before the study was carried out, various hypotheses were formulated, which were either accepted or rejected based on the study results. For example, the position of the imperfection with respect to the driver's or passenger's side is not relevant for the evaluation of an imperfection. However, the gender of the test person has an influence on the evaluation. Female test persons are somewhat more critical than males. The color of the car can also have an influence on the evaluation of imperfections. Research Limitation: The significance of the results may be limited by the selection of test persons. Most of them are still students. Furthermore, the test vehicles are of a certain brand and a certain type, so that a transferability of the results to other vehicle types could be critically discussed. The developed study design works and should be repeated with a larger number of participants and possibly different vehicle types. Value of paper: Automobile manufacturers put enormous effort into the quality control of their vehicles. In terms of cost-benefit considerations, automobile manufacturers have to ask themselves: Do we use the right standards, criteria and methods for the quality control of our vehicles? Since customer orientation is becoming increasingly focused (f. ex. based on ISO 9001:2015 and the general competitive pressure), studies such as this one help to better understand customers and integrate their point of view into everyday production.}, language = {en} } @misc{BraunKuennemannRichetal., author = {Braun, Julia and K{\"u}nnemann, Stephanie and Rich, Beatrice Monique and Mißler-Behr, Magdalena and Woll, Ralf}, title = {Ver{\"a}nderung von Kundenanforderungen in der Automobilindustrie - Analyse von Experteninterviews}, series = {Datengetriebenes Qualit{\"a}tsmanagement : Bericht zur GQW-Jahrestagung 2019 in Aachen}, journal = {Datengetriebenes Qualit{\"a}tsmanagement : Bericht zur GQW-Jahrestagung 2019 in Aachen}, editor = {Schmitt, Robert H.}, publisher = {Springer Vieweg}, address = {Berlin, Heidelberg}, isbn = {978-3-662-62442-5}, doi = {10.1007/978-3-662-62442-5_9}, pages = {144 -- 161}, abstract = {Sich verk{\"u}rzende Produktlebenszyklen stellen Unternehmen vor große Herausforderungen.

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.}, language = {en} } @misc{GoldmannWolterWoll, author = {Goldmann, Christine and Wolter, Anja and Woll, Ralf}, title = {Identifying the challenges of communication within virtual teamwork}, series = {15th International Conference of Education, Research and Innovation, November 7th-9th, 2022, ICERI Proceedings 2022}, journal = {15th International Conference of Education, Research and Innovation, November 7th-9th, 2022, ICERI Proceedings 2022}, publisher = {IATED Academy}, address = {Valencia, Spain}, isbn = {978-84-09-45476-1}, issn = {2340-1095}, doi = {10.21125/iceri.2022.0881}, pages = {3609 -- 3615}, abstract = {In recent years, employees have increasingly been working remotely.

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.

Additive Fertigung ist laut DIN EN ISO/ASTM 52900 ein Prozess, welcher Bauteile aus 3D-Modelldaten schichtweise herstellt. Die grundlegenden Komponenten sind ein Schweißger{\"a}t, welches die ben{\"o}tigte Energie zum Schmelzen des Metalldrahts in den Prozess einbringt sowie eine F{\"u}hrungsmaschine, welche die vorgegebene Geometrie des Bauteils abf{\"a}hrt. Anwendungsbereiche sind Rapid Prototyping und Tooling, Direct Manufacturing und Additive Repair. Die gr{\"o}ßten Vorteile stellen die kosteng{\"u}nstige Anlagentechnik und die hohen Abscheidungsraten dar. Nachteilig am Verfahren sind die mangelnde Prozessstabilit{\"a}t und Wiederholgenauigkeit.

Inzwischen stellen Befragungen in der empirischen Forschung eine der h{\"a}ufig angewendeten Erhebungsmethoden dar [2]. Eine Vielzahl an Informationen existiert zum Thema Fragebogen und dessen Erstellung sowie zur Durchf{\"u}hrung und Auswertung der Befragung. Immer wieder stellen sich {\"a}hnlichen Fragen, die in einem kleinen Leitfaden beantwortet werden sollen. Die Durchf{\"u}hrung einer schriftlichen Befragung folgt h{\"a}ufig einem sehr {\"a}hnlichen Muster. Es existieren bereits Leitf{\"a}den wie „The Tailored Design Method" nach DILLMAN ET AL [3]. Dieser Leitfaden leistet Hilfestellung bei der Erarbeitung eines Fragebogens und verspricht eine hohe Datenqualit{\"a}t und Aussch{\"o}pfungsquote. Der Leitfaden besitzt jedoch keinen Abschnitt {\"u}ber die Datenauswertung [3]. Auf der letzten GQW - Tagung st{\"u}tzte sich ein großer Teil der Beitr{\"a}ge auf Befragungen. Mithin stellte sich die Aufgabe zur Entwicklung eines Leitfadens f{\"u}r Befragungen. Darin werden typische Problemstellungen wie der repr{\"a}sentative Stichprobenumfang, allgemeine Anforderungen an das Design und m{\"o}gliche Fehler adressiert. Zu diesem Zweck wird zun{\"a}chst die bereits vorhandene Literatur analysiert, zusammengefasst und anschließend ein Leitfaden daraus entwickelt. Ergebnisse einer Befragung sollten statistisch belastbar sein, damit abgesicherte Aussagen aus den Ergebnissen abgeleitet werden k{\"o}nnen. Der erstellte Leitfaden soll in die Lehrt{\"a}tigkeiten eingebaut werden und Studierenden bei der Durchf{\"u}hrung belastbarer Umfragen unterst{\"u}tzen. Auf diese Weise wird zur nachhaltigen F{\"o}rderung des Qualit{\"a}tsmanagements-Nachwuchses beigetragen.}, language = {de} }
