The halo effect in sports
(2018)
A halo effect can lead to significantly biased and distorted judgments in numerous situations and settings in daily life. However, its impact has barely been researched in the sporting environment, although it might help a great deal in understanding how sport fans think and behave. This paper provides an international literature review on the halo effect in different research fields. Built upon this state of the art, an empirical study based on two German soccer clubs, VfB Stuttgart and FC Bayern Munich, analyzes the presence of halo effects explained by social identity theory. The study shows that supporters rate aspects of the respective team, for example the president’s competency, more favorable than common sport spectators, and this effect even increases with a higher level of team identification.
Lessons from sports : what corporate managers can learn from international professional sports
(2018)
Although sports is generally defined as motor activity, it has always been much more than that. Since management and sports follow the same objective of achieving highest performance, correlations between these two fields nowadays become increasingly interesting in terms of corporate strategy. This paper aims to point out how organisations as well as individuals can benefit from the general and psychological values and strategies of international professional sports, by first looking at the general framework of professional sports and further applying approaches from various types of sports directly to certain business functions like general management, human resource management and marketing management.
An assessment model to foster the adoption of agile software product lines in the automotive domain
(2018)
A software product line is commonly used for the software development in large automotive organizations. A strategic reuse of software is needed to handle the increasing complexity of the development and to maintain the quality of numerous software variants. However, the development process needs to be continuously adapted at a fast pace to satisfy the changing market demands. Introducing agile software development methods promise the flexibility to react on customers’ change requests and market demands to deliver high quality software. Despite this need, it is still challenging to combine agile software development and product lines. The maturity of an agile adoption is often hard to determine. Assessing the current situation regarding the combination is a first step towards a successful inclusion of agile methods into automotive software product lines. Based on an interview study with 16 participants and a literature review, we build the so-called ASPLA Model allowing self-assessments within the team to determine the current state of agile software development in combination with software product lines. The model comprises seven areas of improvement and recommends a possibility to improve the current status.
Software engineering courses have to deliver theoretical and technical knowledge and skills while establishing links to practice. However, due to course goals or resource limitations, it is not always possible or even meaningful to set up complete projects and let students work on a real piece of software. For instance, if students shall understand the impact of group dynamics on productivity, a particular software to be developed is of less interest than an environment in which students can learn about team-related phenomena. To address this issue, we use experimentation as a teaching tool in software engineering courses. Experiments help to precisely characterize and study a problem in a systematic way, to observe phenomena, and to develop and evaluate solutions. Furthermore, experiments help establishing short feedback and learning cycles, and they also allow for experiencing risk and failure scenarios in a controlled environment. In this paper, we report on three courses in which we implemented different experiments and we share our experiences and lessons learned. Using these courses, we demonstrate how to use classroom experiments, and we provide a discussion on the feasibility based on formal and informal course evaluations. This experience report thus aims to help teachers integrating small- and medium sized experiments in their courses.
The need for creating digitally enhanced products, services, and experiences as well as the emergence of new or modified business models has a significant impact on the automotive domain. Innovative solutions and new topics such as Smart Mobility or Connectivity require current automotive development processes to undergo major changes. They need to be redesigned in a way that it is possible to learn and adapt continuously at a fast pace. Agile methods are promising approaches to address these new challenges. However, agile methods are not tailored to the specific characteristics of the automotive domain such as software product line (SPLs) development. Although, there have been efforts to apply agile methods in the automotive domain, widespread adoptions have not yet taken place.
Software engineering education is supposed to provide students with industry-relevant knowledge and skills. Educators must address issues beyond exercises and theories that can be directly rehearsed in small settings. A way to experience such effects and to increase the relevance of software engineering education is to apply empirical studies in teaching. In our article, we show how different types of empirical studies can be used for educational purposes in software engineering. We give examples illustrating how to utilize empirical studies, discuss challenges, and derive an initial guideline that supports teachers to include empirical studies in software engineering courses.
Software and system development faces numerous challenges of rapidly changing markets. To address such challenges, companies and projects design and adopt specific development approaches by combining well-structured methods and flexible agile practices. Yet, the number of methods and practices is large and the actual process composition is often carried out in an ad-hoc manner. This paper reports on a survey on hybrid software development approaches. We study which approaches are used in practice, how different approaches are combined, and what contextual factors influence the use and combination of hybrid software development approaches.
Back to the future: origins and directions of the “Agile Manifesto” – views of the originators
(2018)
In 2001, seventeen professionals set up the manifesto for agile software development. They wanted to define values and basic principles for better software development. On top of brought into focus, the manifesto has been widely adopted by developers, in software-developing organizations and outside the world of IT. Agile principles and their implementation in practice have paved the way for radical new and innovative ways of software and product development. In parallel, the understanding of the manifesto’s underlying principles evolved over time. This, in turn, may affect current and future applications of agile principles. This article presents results from a survey and an interview study in collaboration with the original contributors of the manifesto for agile software development. Furthermore, it comprises the results from a workshop with one of the original authors. This publication focuses on the origins of the manifesto, the contributors’ views from today’s perspective, and their outlook on future directions. We evaluated 11 responses from the survey and 14 interviews to understand the viewpoint of the contributors. They emphasize that agile methods need to be carefully selected and agile should not be seen as a silver bullet. They underline the importance of considering the variety of different practices and methods that had an influence on the manifesto. Furthermore, they mention that people should question their current understanding of "agile" and recommend reconsidering the core ideas of the manifesto.
The relative pros and cons of using students or practitioners in experiments in empirical software engineering have been discussed for a long time and continue to be an important topic. Following the recent publication of “Empirical software engineering experts on the use of students and professionals in experiments” by Falessi, Juristo, Wohlin, Turhan, Münch, Jedlitschka, and Oivo (EMSE, February 2018) we received a commentary by Sjøberg and Bergersen. Given that the topic is of great methodological interest to the community and requires nuanced treatment, we invited two editorial board members, Martin Shepperd and Per Runeson, respectively, to provide additional views.
Purpose: This study aims to conceptualize and test the effect of consumers´ perceptions of complaint handling quality (PCHQ) in both traditional and social media channels.
Design/methodology/approach: Study 1 systematically reviews the relevant literature and then carries out a consumer and manager survey. This approach aims to conceptualize the dimensionality of PCHQ. Study 2 tests the effect of PCHQ on key marketing outcomes. Using survey data from a German telecommunications company, the study provides an explanation for the differences in outcomes across traditional (hotline) and social media channels.
Findings: Study 1 reveals that PCHQ is best conceptualized as a five dimensional construct with 15 facets. There are significant differences between customers and managers in terms of the importance attached to the various dimensions. The construct shows strong psychometric properties with high reliability and validity, thereby opening up opportunities to treat these facets as measurement indicators for the construct. Study 2 indicates that the effect of PCHQ on consumer loyalty and word-of-mouth (WOM) communication is stronger in social media than in traditional channels. Procedural justice and the overall quality of service solutions emerge as general dimensions of PCHQ because they are equally important in both channels. In contrast, interactional justice, distributive justice and customer effort have varying effects across the two channels.
Research limitations/implications: This study contributes to the understanding of a firm´s channel selection for complaint handling in two ways. First, it evaluates and conceptualizes the PCHQ construct. Second, it compares the effects of different dimensions of PCHQ on key marketing outcomes across traditional and socialmedia channels.
Practical implications: This study enables managers to understand the difference in efficacy attached to different dimensions of PCHQ. It further highlights such differences across traditional and social media service channels. For example, the effect of complaint handling on social media is of particular importance when generating WOM communication.
Originality/value: This study offers a comprehensive conceptualization of the PCHQ construct and reveals the general and channel contingent effects of its different dimensions on key marketing outcomes.
