    Getting agile methods to work for cordys global software product development
    (Springer-Verlag Berlin, 2011-03-14) Van Hillegersberg, Jos; Ligtenberg, Gerwin; Aydın, Mehmet Nafiz
    Getting agile methods to work in global software development is a potentially rewarding but challenging task. Agile methods are relatively young and still maturing. The application to globally distributed projects is in its early stages. Various guidelines on how to apply and sometimes adapt agile methods have been proposed. However, systematic literature reviews reveal that detailed evaluative studies are scarce and limited to small and medium sized projects. This study presents a framework that integrates best practices of adapting and applying agile methods reported in the literature. The framework is applied to analyze the experiences of global software product development company Cordys in a seven year longitudinal case study. Both the framework and the experiences of Cordys documented in this paper will be of value to other larger projects that aim to he successful in applying agile in globally distributed projects.

    A role-based service level NFC ecosystem model
    (Springer, 2013-02) Ok, Kerem; Coşkun, Vedat; Özdenizci Köse, Büşra; Aydın, Mehmet Nafiz
    Near Field Communication (NFC) is a short range wireless communication technology allowing to communicate mobile devices within close proximity. It provides opportunity for service providers to offer various value added services to customers. NFC technology allows the usage of wide range of applications and eliminates the obligation to carry additional components other than the mobile device such as credit or payment cards, tickets, identification cards or keys. Despite its technological advantages over alternative ones, the NFC business ecosystems and services are yet to take off. The problems mainly arise with the business issues triggered by different and mostly conflicting needs of many actors in the ecosystem and several additional technical issues. In this study, by adopting a role-based service ecosystem modeling, we propose an NFC ecosystem model which perfectly specifies the roles in the ecosystem, and defines set of activities for each role, and communication structure. We analyzed NFC ecosystem in three phases as pre-installation, installation, and service usage. We have defined the activities and communication structure in the first two phases, and finally investigated the service usage phase in three different operating modes of NFC. After giving the details of the proposed ecosystem model, two use cases are given to validate the developed ecosystem model. We complete our study by discussing the requirement satisfaction.
