GENERATING DESIGNERS’ KNOWLEDGE ARTIFACTS AS ACTUAL PROTOCOLS IN THE DESIGN PROCESS
In this paper, we explore that designers can generate more effective interactions and decisions in the design process, when they use knowledge artifacts as design protocols with the following research question-- how designers could generate different types of knowledge artifacts with or without actual users in the design process? To address this, we adopt boundary objects as a theoretical foundation to argue the knowledge artifacts that designers produce. As an empirical approach, this study presents two case studies that represent the multiple knowledge artifacts between designers and users in a user-centered design projects. Based on this, it will provide feasible guidelines for designers to create effective knowledge artifacts with and without users as a design vocabulary in their actual design project settings
The liminality of trajectory shifts in institutional entrepreneurship
In this paper, we develop a process model of trajectory shifts in institutional entrepreneurship. We focus on the liminal periods experienced by institutional entrepreneurs when they, unlike the rest of the organization, recognize limits in the present and seek to shift a familiar past into an unfamiliar and uncertain future. Such periods involve a situation where the new possible future, not yet fully formed, exists side-by-side with established innovation trajectories. Trajectory shifts are moments of truth for institutional entrepreneurs, but little is known about the underlying mechanisms of how entrepreneurs reflectively deal with liminality to conceive and bring forth new innovation trajectories. Our in-depth case study research at CarCorp traces three such mechanisms (reflective dissension, imaginative projection, and eliminatory exploration) and builds the basis for understanding the liminality of trajectory shifts. The paper offers theoretical implications for the institutional entrepreneurship literature
A systematic review of protocol studies on conceptual design cognition: design as search and exploration
This paper reports findings from the first systematic review of protocol studies focusing specifically on conceptual design cognition, aiming to answer the following research question: What is our current understanding of the cognitive processes involved in conceptual design tasks carried out by individual designers? We reviewed 47 studies on architectural design, engineering design and product design engineering. This paper reports 24 cognitive processes investigated in a subset of 33 studies aligning with two viewpoints on the nature of designing: (V1) design as search (10 processes, 41.7%); and (V2) design as exploration (14 processes, 58.3%). Studies on search focused on solution search and problem structuring, involving: long-term memory retrieval; working memory; operators and reasoning processes. Studies on exploration investigated: co-evolutionary design; visual reasoning; cognitive actions; and unexpected discovery and situated requirements invention. Overall, considerable conceptual and terminological differences were observed among the studies. Nonetheless, a common focus on memory, semantic, associative, visual perceptual and mental imagery processes was observed to an extent. We suggest three challenges for future research to advance the field: (i) developing general models/theories; (ii) testing protocol study findings using objective methods conducive to larger samples and (iii) developing a shared ontology of cognitive processes in design
Design Ltd.: Renovated Myths for the Development of Socially Embedded Technologies
This paper argues that traditional and mainstream mythologies, which have
been continually told within the Information Technology domain among designers
and advocators of conceptual modelling since the 1960s in different fields of
computing sciences, could now be renovated or substituted in the mould of more
recent discourses about performativity, complexity and end-user creativity that
have been constructed across different fields in the meanwhile. In the paper,
it is submitted that these discourses could motivate IT professionals in
undertaking alternative approaches toward the co-construction of
socio-technical systems, i.e., social settings where humans cooperate to reach
common goals by means of mediating computational tools. The authors advocate
further discussion about and consolidation of some concepts in design research,
design practice and more generally Information Technology (IT) development,
like those of: task-artifact entanglement, universatility (sic) of End-User
Development (EUD) environments, bricolant/bricoleur end-user, logic of
bricolage, maieuta-designers (sic), and laissez-faire method to socio-technical
construction. Points backing these and similar concepts are made to promote
further discussion on the need to rethink the main assumptions underlying IT
design and development some fifty years later the coming of age of software and
modern IT in the organizational domain.Comment: This is the peer-unreviewed of a manuscript that is to appear in D.

Inspirational Bits - Towards a Shared Understanding of the Digital Material
In any design process, a medium’s properties need to be considered. This is nothing new in design. Still we find that in HCI and interactive systems design the properties of a technology are often glossed over. That is, technologies are black-boxed without much thought given to how their distinctive properties open up design possibilities. In this paper we describe what we call inspirational bits as a way to become more familiar with the design material in HCI, the digital material. We describe inspirational bits as quick and dirty but fully working systems in both hardware and software built with the aim of exposing one or several of the dynamic properties of a digital material. We also show how they provide a means of sharing design knowledge across the members of a multi-disciplined design team
Design: One, but in different forms
This overview paper defends an augmented cognitively oriented generic-design
hypothesis: there are both significant similarities between the design
activities implemented in different situations and crucial differences between
these and other cognitive activities; yet, characteristics of a design
situation (related to the design process, the designers, and the artefact)
introduce specificities in the corresponding cognitive activities and
structures that are used, and in the resulting designs. We thus augment the
classical generic-design hypothesis with that of different forms of designing.
We review the data available in the cognitive design research literature and
propose a series of candidates underlying such forms of design, outlining a
number of directions requiring further elaboration
The TASTE Toolset: turning human designed heterogeneous systems into computer built homogeneous software.
The TASTE tool-set results from spin-off studies of the ASSERT project, which started in 2004 with the objective to propose innovative and pragmatic solutions to develop real-time software. One of the primary targets was satellite flight software, but it appeared quickly that their characteristics were shared among various embedded systems. The solutions that we developed now comprise a process and several tools ; the development process is based on the idea that real-time, embedded systems are heterogeneous by nature and that a unique UML-like language was not helping neither their construction, nor their validation. Rather than inventing yet another "ultimate" language, TASTE makes the link between existing and mature technologies such as Simulink, SDL, ASN.1, C, Ada, and generates complete, homogeneous software-based systems that one can straightforwardly download and execute on a physical target. Our current prototype is moving toward a marketed product, and sequel studies are already in place to support, among others, FPGA systems
