Using blockchain technology to extend the vendor managed inventory for sustainability

Nowadays, Information Technology (IT) is changing the way traditional enterprise management concepts work. One of the most dominant IT achievements is the Blockchain Technology. This technology enables the distributed collaboration of stakeholders for their interactions while fulfilling the security and consensus rules among them. This paper has focused on the application of Blockchain technology to enhance one of traditional inventory management models. The Vendor Managed Inventory (VMI) has been considered one of the most efficient mechanisms for vendor inventory planning by the suppliers. While VMI has brought competitive advantages for many industries, however its centralized mechanism limits the collaboration of a pool of suppliers and vendors simultaneously. This paper has studied the recent research for VMI application in industries and also has investigated the applications of Blockchain technology for decentralized collaboration of stakeholders. Focusing on sustainability issue for total supply chain consisting suppliers and vendors, it has proposed a Blockchain based VMI conceptual model. The different capabilities of this model for enabling the collaboration of stakeholders while maintaining the competitive advantages and sustainability issues have been discussed.

THE POSITIVE IMPACT OF AGILE RETROSPECTIVES ON THE COLLABORATION OF DISTRIBUTED DEVELOPMENT TEAMS – A PRACTICAL APPROACH ON THE EXAMPLE OF BOSCH ENGINEERING GMBH

To counteract competitive pressure, increasing customer requirements and growing product complexity successful distributed collaboration in product development is vital. Companies have to face new challenges, such as efficiency losses in communication. To overcome these challenges agile working practices, such as agile retrospectives, could be beneficial. The objective of this scientific work is to evaluate the benefit of agile working practices on the example of agile retrospectives, for the improvement of collaboration in distributed development teams. Based on literature analysis, qualitative and quantitative expert interviews following the DRM by Blessing and Chakrabarti, this scientific work shows that agile working practices have a high potential to improve distributed collaboration. To address this potential, several virtual agile retrospectives are developed and conducted within a distributed team at Bosch Engineering GmbH. The evaluation of this approach results in a high potential of agile retrospectives indicating an improvement tendency. Especially iteratively implemented virtual agile retrospectives have a positive impact on successful distributed collaboration.

The Impact of COVID-19 in Collaborative Programming. Understanding the Needs of Undergraduate Computer Science Students

Collaborative learning activities have become a common practice in current university studies due to the implantation of the EHEA. However, the COVID-19 pandemic has led to a radical and abrupt change in the teaching–learning model used in most universities, and in the way students’ group work is carried out. Given this new situation, our interest is focused on discovering how computer science students have approached group programming tasks. For this purpose, we have designed a cross-sectional pilot study to explore, from both social and technological points of view, how students carried out their group programming activities during the shutdown of universities, how they are doing them now, when social distance must be maintained, and what they have missed in both situations. The results of the study indicate that during the imposed confinement, the students adopted a programming model based on work division or distributed peer programming, and very few made use of synchronous distributed collaboration tools. After the lockdown, the students mostly opted for a model based on collaborative programming and there was an increased use of synchronous distributed collaboration tools. The specific communication, synchronization, and coordination functionalities they considered most useful or necessary were also analyzed. Among the desirable features included in a software for synchronous distributed programming, the students considered that having an audio-channel can be very useful and, possibly, the most agile method to communicate. The video signal is not considered as very necessary, being in many cases rather a source of distraction, while textual communication through a chat, to which they are very accustomed, is also well valued. In addition, version control and the possibility of recovering previous states of the practical projects were highly appreciated by the students, and they considered it necessary to record the individual contributions of each member of the team to the result.
