In software development organizations, large-scale distributed projects pose many challenges, such as hierarchical requirements, large team size, and managing workflow. Agile methods, like Scrum, seem to have limitations in addressing those issues. Kanban offers an interesting alternative in this concern by setting work-in-progress (WIP) limits to manage flow and establishing visibility of requirements using a visual signaling system. However, only few empirical studies have investigated scaling Kanban for large organizations. To address this concern, a case study was conducted in a large multisite company to identify the challenges and possible solutions in scaling Kanban. During the study, defining WIP limits, coordinating with distributed teams, and dividing features between teams were found as major challenges. Setting WIP limits by common agreement between teams and visualizing product backlogs and teams on electronic board, with teams pulling features from the board, were found as possible solutions for overcoming the mentioned challenges.

It is crucial to promote the use of cleaner transport modes, and new technologies are key to achieve this goal. Most mobile-based solutions are focused on services related with the journey itself (mobile ticketing, real-time traffic information and trip planners). Adopting a holistic point of view, and considering every trip has a purpose (work, school, shopping and entertainment), a new service approach is considered. This paper presents a multiservice approach that links city services and public transport to encourage the use of sustainable transport modes. This multiservice approach is based on mobile technologies, which are a unique channel of interaction between service providers and customers. The conceptual model of this approach is materialized in a concrete example. This multiservice approach may represent a step towards a sustainable mobility, while improving the image and efficiency of Public Transport Operators (PTOs), boosting local businesses loyalty and sales and bringing convenience, better service quality and monetary savings to customers.

At Unruly we are constantly trying to turn up the dial on our XP practices, and in the second half of 2014 we started to take the step from Pair Programming on all production code to Mob Programming with the entire team. This report shares experiences that Unruly has gained in pushing the boundaries of Extreme Programming.

Traditionally, software engineering has been dominated by stand-alone development organizations and collaborations between contractors, integrators and suppliers. In the last decade, the notion of software ecosystems has been established as a new paradigm in software engineering. In its essence it proposes participative engineering across independent development organizations centered on a common technology. This paper reviews the current state-of-the-art and presents a first step towards a typification of successful software ecosystems. We discuss key characteristic of the ecosystem types and present a set of example cases. The characterization reviews and consolidates existing research and discusses variations within the key building block of a software ecosystem. It further enables sharpening the borders of what an ecosystem is (and what not) and how the individual types can be differentiated. Thus, this paper contributes to widening the understanding of software ecosystems and serves to prepare a software ecosystem taxonomy.

Cloud Computing technology and services despite the advantages they bring to the market have created number of issues regarding the security and trust of the individuals using them. Incidents occurring in cloud computing environments are hard to be solved since digital forensic methods used to conduct digital investigations are not suitable for cloud computing investigations since they do not consider the specific characteristics of the Cloud. However, designing services over the cloud that will support and assist an investigation process when an incident occurs is also of vital importance. This paper presents a conceptual model for supporting the development of a cloud forensics method and process, thus assisting information systems developers in building better services and investigators to be able to conduct forensics analysis in cloud environments.

This paper presents an application of the importance-performance analysis (IPA) to identify opportunities for improving service quality in retail contexts. This work builds previous quality scales prevalent in service management literature. Data was collected for customers' quality expectations and perceptions across two different retail store formats in Portugal: supermarkets and hypermarkets. The results of the study suggested that managerial decisions regarding service in stores should be adjusted to the characteristics of each retail format. Data analysis supported the existence of differences in the IPA, between supermarkets and hypermarkets, notably for quality dimensions related to reliability and personal interaction.

The presented study examines the prevailing espoused values of some of the most successful software organizations and evaluates the extent to which they are promoted in the agile ideology. Its objective is to determine the level of value congruence and whether it could be used to further explain the widespread adoption of agile software development. Its findings reveal a perfect match between the prevailing espoused values of the examined global software leaders and the agile ideology, and suggest that the popularity of the agile methods might be explained through their capability to increase customer value, facilitate collaboration and teamwork, secure continuous improvement and ensure high quality of delivered products and services.

Virtual enterprises (VEs) are temporary and loosely coupled alliances of businesses that join their skills to catch new business opportunities. However, the dependencies among the activities of a prospective VE cross the boundaries of the VE constituents. It is therefore crucial to allow the VE constituents to discover their local views of the interorganizational workflow, enabling each company to re-shape, optimize and analyze the possible local flows that are consistent with the processes of the other VE constituents. We refer to this problem as VE process fusion. Even if it has been widely investigated, no previous work addresses VE process fusion in the presence of privacy constraints. In this paper we demonstrate how private intersection of regular languages can be used as the main building block to implement the privacy preserving fusion of business processes modeled by means of bounded Petri nets.

This study investigates the effects of social presence and synchronicity on the creation of mutual trust and understanding between conflicting parties in negotiations. An experimental study was conducted in which participants negotiated either face-to-face, through synchronous chat or through asynchronous e-mail. The results show that the high social presence in FtF communication seems to enhance the feelings of trust and understanding the negotiator has in the other party compared to the online negotiations, but not the amount of understanding and trust the other party has in him/her. Synchronicity does not seem to have an influence on the negotiation processes since both the synchronous chat and the asynchronous e-mail condition have equal scores on mutual trust and understanding.

Conformance checking is becoming more important for the analysis of business processes. While the diagnosed results of conformance checking techniques are used in diverse context such as enabling auditing and performance analysis, the quality and reliability of the conformance checking techniques themselves have not been analyzed rigorously. As the existing conformance checking techniques heavily rely on the total ordering of events, their diagnostics are unreliable and often even misleading when the timestamps of events are coarse or incorrect. This paper presents an approach to incorporate flexibility, uncertainty, concurrency and explicit orderings between events in the input as well as in the output of conformance checking using partially ordered traces and partially ordered alignments, respectively. The paper also illustrates various ways to acquire partially ordered traces from existing logs. In addition, a quantitative-based quality metric is introduced to objectively compare the results of conformance checking. The approach is implemented in ProM plugins and has been evaluated using artificial logs.
