Entwicklung und Test eines Prototypen nach den Maßstäben des Usage Centered Desings (nach Constantine und Lockwood). Der Prototyp beschäftigt sich mit der Organisation / Planung von Schulungen im Kontext geflüchteter Menschen in den Ländern Südsudan und Uganda und verfolgt dabei den mobile first Ansatz. Augenmerk wird auf die Gestalung einer benutzungsoptmierten Applikation in einem kulturell fremden Kontext gelegt.:I. Einleitung A. Krieg im Südsudan und dessen Auswirkungen B. #ASKnet 1. Ziel 2.

Dans le domaine du projet de conception-construction architecturale, la gestion de la collaboration entre les différents acteurs d'un projet est un enjeu important. D'un projet à un autre, en fonction du projet, mais aussi des acteurs qui y interviennent, les pratiques de travail varient. Parallèlement, de nombreux services sont proposés et utilisés pour assister la collaboration, certains sur un modèle « grand public » et d'autres plus orientés vers un usage professionnel. L'expérience CRTI-weB est un projet de développement d'un collecticiel mené avec et pour les professionnels du secteur au Luxembourg. Malgré l'étude des besoins métiers menée en amont du développement, l'outil présente cependant des manques d'adaptation. Ce constat d'inadaptation n'est pas un cas isolé, il reflète une lacune générale de ce genre d'outils à satisfaire pleinement les attentes des professionnels. C'est pourquoi ce travail doctoral propose un cadre d'analyse supporté par la modélisation des comportements des utilisateurs. Nous adoptons alors plusieurs points de vue relatifs à différents champs de recherches : le génie logiciel, la conception d'interfaces homme-machine, l'entreprise orientée services et la conception de système d'information, et enfin le travail collaboratif assisté par ordinateur (TCAO). Nous proposons la méthode PUSH (Practices and Usages based Services enHancement) qui orchestre ces différents points de vue et permet de générer un ensemble d'exigences pour le développement de services dits « adaptés ». Communication et traçabilité sont les maitres mots de cette méthode de conception. Le contexte d'étude à la fois orienté recherche et développement nous a permis d'évaluer et d'améliorer la définition des concepts mis en avant ainsi que la mise en place de la méthode PUSH à travers trois expérimentations / In the sector of the architectural design-construction project, the management of the collaboration between the different actors of a project is an important issue. From a project to another, considering the project type and also the actors involved, business practices vary. In parallel, many services are proposed and used to assist the collaboration, some of them being generic and others more specific to professional usage. The CRTI-weB experience is a groupware development project lead with and for professionals of the Luxembourgish sector. Despite the analysis of business needs lead before development, the tool has some lacks of adaptation. This statement isn't isolated; in general, this type of tools doesn't fully satisfy professionals' expectations. This doctoral work proposes an analysis framework supported by users' behaviors modeling. We adopt several viewpoints related to several research fields: software engineering, human-computer interactions design, service-oriented enterprise and information system design, and finally computer-supported collaborative work (CSCW We propose the PUSH method (Practice and Usages based Service enhancement) that orchestrates the different viewpoints to generate an amount of requirements for the development of adapted services. The communication and the traceability are supported by this design method. The context of study, both research and development-oriented (through the collaboration of the MAP-CRAI laboratory in Nancy and the CRP Henri Tudor in Luxembourg) allows us evaluating and enhancing the definition of our concepts and the applicability of the PUSH method through three experimentations

The following degree project is written within the department of Information Technology at Uppsala University. The subject studied is the difference between academic user research and such user research performed by professionals at commercially driven companies. Academic’s and professional’s agendas, interests and approaches seem to differ and consequently a gap emerges. To perform a comparison between academically defined and practically defined user research a case study and a literature study were conducted. During the literature study three main academic approaches to perform user research were studied and summarized in a unified view. The case study was performed over 4 months at Spotify in the User Research team to gain insights into how user research is conducted in a commercially driven company. The degree project shows that academics and professionals can benefit from each other. For example, academics can integrate various mix methods to better understand design and concepts and base assumptions on more reliable data. Professionals can benefit from academics by adapting a similar systematic approach to perform user research and have a larger impact on the development.
