With the increasing relevance of smartphones, more and more companies are trying to use mobile apps for their business purposes. At the same time, the digital transformation and online trade are putting increasing pressure on the stationary retail trade. Many retailers are therefore looking for ways to use mobile apps to attract new customers or retain existing ones. With the growing number of mobile apps in the app marketplaces, the sustainable loyalty of app users is becoming an increasing challenge. For retailers, the question arises as to which determinants influence consumer acceptance of mobile apps in retail. From an initial 44,800 search results at Google Scholar, 18 scientific papers are analyzed in a qualitative synthesis by means of a systematic review based on the PRISMA schema. In general, perceived value, practical benefits and user-friendliness are identified as determinants. In addition, the importance of linking the mobile app to the stationary POS and the function of mobile apps in retail more as digital shopping assistants and less as online stores is highlighted. The retailer who publishes the app itself also plays an important role in the consumer acceptance of the app.

Using push notifications, companies can address their smartphone app users with advertising messages. Each of these notifications can mean added value for smartphone users in terms of content, but also disruption and interruption. It is therefore important for advertisers to understand how the frequency of message delivery influences consumer acceptance. The systematic review is based on the PRISMA method and initially identifies a total of 18,725 potentially relevant scientific papers. The 17 research articles included in the qualitative synthesis show that push notifications are suitable for encouraging users to use an app and establish new habits. App usage increases with frequency, with particularly active users tolerating higher frequencies. At the same time it is also shown that too high a frequency can be perceived as disturbing and users should therefore be given the opportunity to determine the frequency with which they receive notifications. A gap in research has been identified in particular in studies that look at real observed behaviour of app users instead of behaviour reported via questionnaires and examine the interaction of frequency, content and presentation of notifications.

In the context of managing digital enterprise transformation, the generation and distribution of knowledge across the entire organization is of great importance. Because existing processes are being questioned and activities are changing, the promotion of organizational learning should be part of the digital transformation strategy. This chapter uses the example of Scrum to show how organizational learning can be supported by agile working methods. After an introduction to organizational learning and to Scrum as a process of continuous improvement, the four elements of organizational learning are used and compared to the characteristic elements of Scrum. In addition, the author points out existing research gaps, especially in quantitative research, and gives practical advice for managers on how to use Scrum to promote organizational learning.

With the spread of mobile smartphone apps among consumers, they have also become increasingly important for e-commerce companies in recent years to attract customers. A central challenge in the use of smartphone apps by companies is the acquisition and activation of new app users. This case study examines how incentives like coupons and bonus points to download an e-commerce app via other smartphone apps, so-called "medium apps", have an effect. After a review of existing literature on similar topics, hypotheses regarding the probability of installation and actual app usage are developed and tested in an experiment. The hypotheses can be confirmed to a large extent, but especially coupons for the advertised online shop that publishes the e-commerce app do not show the expected effect. Further research questions are identified and practical recommendations for app marketing are derived.
