Current requirements engineering practices for gathering user input are characterized by a number of communication gaps between users and engineers which might lead to wrong requirements. The problem situations and context which underlie user input are either gathered back in time, or submitted with wrong a level of details. We think that making user input a first order concern of both software processes and software systems harbours many innovation opportunities. We propose and discuss a continuous and context-aware approach for communicating user input to engineering teams and other users, by a) instrumenting the problem domain, b) proactively recommending to share feedback and c) annotating graphical interfaces.]]>

Wikis have emerged as easy and flexible tools for accessing and sharing knowledge on the internet and within organizations. Due to their highly collaborative nature, users can typically modify and create content without any access restrictions since these are replaced by social practices. On the other hand, due to the lack of central guidance, knowledge sharing is driven by the individual choice of contributors. We claim that – especially in enterprise settings – the lack of guidance for content creation is a major problem. We therefore analyze search and knowledge sharing in current Wikis. To improve knowledge sharing, we present the Woogle concept, which introduces “Social Search” and “Need-driven Knowledge Sharing” into Wikis. We describe our prototype implementation Woogle4MediaWiki and results from initial evaluation studies.]]>

Knowledge sharing between individuals has traditionally been conducted using faceto- face conversation. In the networked society – initially formed by telegraphs and the phone and nowadays powered by the Internet – many acts of knowledge sharing are carried out in a mediated fashion. While this typically introduces a number of problems in the knowledge sharing process, it also offers certain advantages. In this paper, we describe a framework for analyzing different modes of knowledge sharing.

Enterprise Search engines are strong in locating existing documents and information in an organization while Wikis are designed to capture new information in a lightweight and collaborative fashion. Conversely, Wikis are rather bad in locating information (especially from external documents) while Enterprise Search does not address the provision of new information and socializing around information needs. Therefore we argue that both systems focus on specific parts of the organizational information process, which should indeed be combined in order to improve enterprise information exchange. We discuss “Woogle” as a concept to integrate Enterprise Search into Wikis and describe its reference implementation “Woogle4MediaWiki”.]]>

"Annals of Knowledge Sharing in Distributed Software Development Environments: Experience from Open Source Software Projects" (Sulayman K. Sowe, Rishab A. Ghosh and Luc Soete) Empirical research aimed at understanding how individuals interact and share their knowledge in a distributed software development environment has traditionally been very difficult because the source of knowledge, the code, has been a guarded secret and software developers and users were seldom in contact, thus making it difficult to study, in situ, all the individuals involved in the software development process. Free/Open Source Software (F/OSS) projects presents renewed opportunities, as well as challenges, in understanding collaboration and knowledge sharing amongst software developers and users in distributed software development environments. In this paper, we discuss how developers and users share their knowledge and collaborate in the software development process. Knowledge sharing metrics, software repositories, and suitable methodologies for studying knowledge sharing are presented. The paper aims to stimulate discussion, present our current understanding, and empirical research opportunities and challenges in knowledge sharing in distributed collective practices - F/OSS projects.]]>

"Investigating the Suitability of Web X.Y Features for Software Engineers" (Eric Ras, Jörg Rech, Sebastian Weber) Today, software engineers strongly rely on information while they perform development activities in the different software engineering (SE) phases. The results of a previous survey showed that most information is required during the phases of requirements engineering (RE), design, programming, and project management. Web X.Y features (i.e., concepts and technologies) facilitate collaboration and communication with distributed individuals and help to cope with the immense amount of information by simplifying the organization, integration, and reuse of information scattered across diverse content sources. After presenting the features of the different Web X.Y generations (i.e., Web 2.0, Web 2.5, and Web 3.0), we propose a weighted mapping for the relevancy of these Web X.Y features regarding their support for the four SE phases with the highest need for information. Based on this subjective mapping, a set of research questions and hypotheses is derived that form the basis of an empirical survey. The goal of this survey is to investigate the potential of Web X.Y features for SE.]]>

"Supporting Software Development Teams with a Semantic Process- and Artifact-oriented Collaboration Environment" (Sebastian Weber, Andreas Emrich, Jörg Broschart, Eric Ras and Özgür Uenalan) The focus of this paper is on how to support small software teams in tailoring and following organization-specific process models by using a lightweight and flexible approach to reduce the visible complexity of software projects. We introduce the SPACE (Semantic Process- and Artifact-oriented Collaboration Environment) concept, which describes working processes and an associated approach. These models are integrated semantically, thereby enabling various kinds of analytic techniques, and thus making it easier to cope with the complexity of processes. Pre-defined templates can be configured to actual working processes and artifacts exchanged in such processes. In this paper, we adapt SPACE to the software engineering domain by using the domain-specific Software Organization Platform (SOP). In this context, the templates contain process and artifact descriptions of software process models, such as V-Model, RUP, or agile development.]]>

"A Method for Identifying Unobvious Requirements in Globally Distributed Software Projects" (Smita Ghaisas) We present requirements elicitation method and an assisting toolset to identify unobvious requirements in globally distributed projects. We demonstrate use of social software principles and technologies in distributed and collaborative requirements elicitation with a purpose to detect unobvious requirements. In our experience, stakeholders are rarely clear on their requirements. During requirements elicitation workshops (that involve face-to-face communications), they are not able to visualize all the pertinent scenarios. They can typically articulate ‘first-order’ scenarios resulting out of direct interactions (among stakeholders and between stakeholders and proposed systems), but they find ‘second-order’ scenarios that result out of multiple stimuli are hard to detect a-priori. We refer to such ‘hard to detect’ requirements as ‘unobvious’. In globally distributed situations, this challenge becomes even more pronounced due to lack of frequent and informal communications that allow iterative refinements of stakeholder inputs. We describe an approach that addresses this problem. Our approach includes identification of representative roles and construction of method chunks that include a step-by-step guidance for roles to practice the method chunks relevant to them. Towards this purpose, we have developed a web 2.0 based toolset that presents the method chunks to appropriate roles, synchronizes activities performed by the roles by providing relevant notifications and automates some of the activities recommended in the method. Web2.0 has been chosen as a platform to deliver our method in the light of architecture of participation that it offers. The identification of unobvious requirements has been demonstrated through the results of a case study in Insurance domain.]]>
