La posture créative est à l’innovation ce que l’excellence opérationnelle est à l’entreprise: une démarche désormais incontournable. Et pourtant les plus sceptiques poussent nos communautés, avec raison, à poursuivre la réflexion: que reste-t-il à apprendre des méthodes créatives divergentes, comme le brainstorming par exemple ? Comment éviter à l’avenir la mise en œuvre répétitive et décontextualisée de recettes « toutes faites » qui dénaturent la créativité et nuisent à sa crédibilité ? Ces inquiétudes seront analysées par Catherine Elsen à la lumière du Design Thinking, cette approche méthodologique qui pourrait bien faire favorablement évoluer les représentations et accompagner chaque entreprise dans la mise en œuvre d’un modèle créatif qui lui correspond réellement. Esquissée dès la fin des années 80 aux Etats-Unis par des entrepreneurs et innovateurs tels que David Kelley (fondateur d’IDEO, directeur de la d.school, Université de Stanford) ou Tim Brown (CEO actuel d’IDEO), la méthode repose sur deux piliers fondamentaux: l’approche empathique (du marché, des utilisateurs, mais aussi de l’entreprise elle-même) et le « quick and rough prototyping » (ou « protocept »), soit une matérialisation itérative précoce des idées, que certains qualifient d’agile. L’intervention abordera ces fondamentaux théoriques et leur mise en œuvre pratique au travers d’exemples d’applications et d’outils ré-appropriables. [less ▲]

This paper specifically focuses on one aspect of the experience design process, sometimes even stressed as one if its shortcomings: the time it takes to properly gain insights about possible real-life experiences of proximal or distal end-users. In the process of making sense of sometimes conflicting viewpoints found in the literature about timing and its possible impact on design processes and outcomes, this paper compares four distinct settings and addresses the following research questions: • How “time-framing” the design process possibly filters (positively or negatively) the awareness designers have about end-users; • How the experimental protocols, their inherent limitations and artificialities, do shape the designers’ involvement in the process of designing for an end-user’s experience. Results put techniques for «disciplined creativity», such as brainstorming or analogies, front-to-front with more reflective approaches that unfold over more time, and discuss respective but complementary added values of both.

The paper describes the way expertise and field-knowledge can impact the transfer of graphical intentions during architectural cooperative design. The analysis of 28 controlled experiments reveals what matters in transmitting architectural intents and more specifically underlines how novices’ intuitive, deductive processes based on previous and embodied experiences interestingly complement experts’ knowledge of the architectural field and its semantics. The results directly inform how we, as researchers, designers and engineers, should take advantage of both novices’ and experts’ strategies to develop tools, methods or interfaces to support next generation cooperative design.

In response to questions about designers’ visual way of knowing and working, this article explores how sensory experience is conveyed during the early phases of architectural design. By processing 985 graphic components issued from a three-month ethnographic observation inside an architecture firm, and proposing an original methodology for their analysis, we identify and analyse graphic expressions of sensory-related design intentions. Multi-sensory dimensions of experiencing an architectural artefact, and the way architects deal with users experiencing space differently, are topics also considered in this article. The resulting observations remind us not to mistake apparent lack of graphical clues with lack of sensibility when it comes to addressing sensory experience during architectural design. [less ▲]

La pensée créative est à l’innovation ce que les méthodes sont à la recherche scientifique: une base essentielle. Longtemps associés à une certaine part de mystère, les mécanismes intrinsèques de la créativité sont aujourd’hui peu à peu décryptés par les communautés de chercheurs actifs en ingénierie de la conception, en sciences sociales ou en psychologie. Un consensus semble se dégager quant à l’étendue de son application: la véritable valeur ajoutée de la créativité apparaît lorsqu’elle est appliquée, telle une culture d’entreprise, à toutes les strates d’un projet et lorsqu’elle est mise en oeuvre, sans distinction, par tout un chacun. Forts de ce constat, des entrepreneurs et inventeurs tels que David Kelley (fondateur d’IDEO, directeur de la d.school, Université de Stanford) ou Tim Brown (CEO actuel d’IDEO) ont activement développé une approche appelée le "Design Thinking". Celle-ci vise à démystifier et «décomplex(ifi)er» certains procédés favorisant la créativité et ainsi parvenir à décomplexer les acteurs généralement considérés comme «non créatifs». L’intervention abordera, au travers d’une vingtaine de «success stories», les concepts de base de la démarche. Elle se voudra avant tout à la portée de ceux et celles qui désirent ré-intégrer la créativité au sein de leur pratique professionnelle et, en finalité, augmenter leur potentiel innovant. [less ▲]

The goal of this paper is to reexamine assumptions about Sketch-Based Interfaces for Modeling in the context of designers’ needs and practices. Research questions examine (i) the type of sketch support and (ii) the timing of support. Both concepts try to determine when, what, why and how to augment design processes in a way that is useful to designers. Two experiments (one in architecture and one in product design) based on ergonomics theory are conducted and intend to question some of these assumptions. The “Port Zeeland” experiment examines how twenty novices perceive and copy a blurred architectural sketch, which provides clues for a sketch interpretation system. “Tragere” experiment studies how 12 professional product designers, some of whom are “idea-generators” and others “idea-pursuers”, perceive, recognize and handle a design sketch. The results take a designer’s point of view in assessing the timing and value of sketch assistance in product design. The quantitative data analysis provides rich clues about when, why and how product sketches should be supported. The paper explores the strategies developed by designers to perceive and recognize graphical content, and discusses the generation of 3D volumes, the univocity state between sketches and 3D models, and the treatment of features in freehand sketches. The paper concludes with observations on the timing and value of support, as first integrated in NEMo, a tool for early stage architectural design, and then in PEPS3, an early stage framework for product design.

Sketching and prototyping of design concepts have long been valued as tools to support productive early stage design. This study investigates previous findings about the use and timing of use of such design tools. This study considers such tools in the context of team design projects. General trends and statistically significant results about “sketchstorming” and prototyping suggest that, in certain constrained contexts, the focus should be on the quality of information rather than on the quantity of information generated, and that prototyping should begin as soon as possible during the design process. Ramifications of these findings are discussed in the context of educating future designers on the efficient use of design tools. [less ▲]

Understanding collaborative design goes far beyond analyzing group dynamics, tasks allocations or negotiation during decision-making processes. In this paper, we focused on the collaborative sketching process, during which the intentions of designers are supported by their sketches and by specific strokes.Twelve professional designers attended an experimental design session, where they were asked to express, share, capture or interpret sketches. A qualitative and quantitative fine-grained analysis of strokes teach us (i) how designers tend to deal with representations that are not theirs; (ii) what main graphical key-features constitute the inner nature of the shared information and (iii) how and when can this graphic essence be shared with collaborators.

The preliminary ideation phase, determining more than 70 % of a project’s total costs, is a crucial part of the design process. It usually gathers several actors around the innovative solving process of a complex problem : it merges their complementary expertise, the use of mediating objects as well as a mysterious part of creativity in order to reach a solution if not innovative, at least satisfactory. With the introduction of always more powerful Computer Aided Design tools, industrial design sees its every-day practices drastically evolving : these software still not support designers during their preliminary design phases and free-hand sketches, on the other hand, encounter increasing difficulties to meet today time-to-market pressures. This thesis analyzes free-hand sketches’ and CAD tools’ respective and complementary strengths as supports to preliminary design phases. Advanced design engineering concepts, nurturing the study of the particular articulation existing between both mediating objects, are associated with dedicated Human Factors methodologies for the analysis of every-day professional practices. The research project draws its main qualitative and quantitative results from three field studies and two experimentations, bringing together more than forty professional designers and three design companies. Its multi-disciplinary approach leads to models and recommendations that directly nurture the definition of a new design support system. The specifications tend to respect, augment or, on the contrary, reject some aspects of these mediating objects and aim at supporting a design process always in respect with designers’ constraints and real needs. Beyond the concepts of our support system, we discuss some results that are of interest for communities of design engineering and human-computer interaction. Among these results are : - the extension of the preliminary design phase’s boarders ; - the non-dichotomous approach of rough and detailed mediating objects ; - the coexistence of two design moves : in addition to Schön’s «see-transform-see» theory, the externalization of a strong mental image or a strong pre-inventive form explains the early uses of CAD tools ; - the study of tool’s uses and misuses and graphic and semantic contents of external representations all along the design process, reintroduced in a simplified four-steps model ; the study of shifts occurring between 2D and 3D representations and their implications for the system’s automatization ; - and, at the strokes’ scale, the study of the exploitable key-features and the strokes’ cycles and their implications for the temporality of assistance. The thesis also discusses the added-value of its theoretical and methodological background for the materialization of a design-engineering community that articulates designer, mediating objects, design process and end-users in a coherent system, sound basis for the specification of adapted and adopted design support systems.

Une méthodologie de traitement et d’analyse des informations récoltées est présentée (approche chronologique et analyses « verticales » sur base de lignes du temps). Celle-ci nous permet de tracer les nombreuses adaptations dont font preuve les acteurs tout au long de leur processus: adaptations de leurs outils et représentations, de leurs modalités de travail individuelles ou collaboratives, adaptations et développement de nouvelles compétences.

This paper questions the new uses of design tools and representations in the industrial field. A two months in situ observation of real industrial practices shows (i) how strongly CAD (Computer-Aided Design) tools are integrated in work practices, in preliminary design phases as well, and (ii) how design actors sometimes deviate this tool from its initial objectives to use it in complement of sketches’ contributions. A multi-layered study built on an anthropo-based approach helps us to deepen the “mediating objects” analysis. It also suggests considering the complementarities of design tools instead of their differences in order to propose another kind of design support tool. [less ▲]
