    This is the first part of a two-part paper presenting a fundamental review and summary of research of design coordination and cooperation technologies. The theme of this review is aimed at the research conducted within the decision management aspect of design coordination. The focus is therefore on the strategies involved in making decisions and how these strategies are used to satisfy design requirements. The paper reviews research within collaborative and coordinated design, project and workflow management, and, task and organization models. The research reviewed has attempted to identify fundamental coordination mechanisms from different domains, however it is concluded that domain independent mechanisms need to be augmented with domain specific mechanisms to facilitate coordination. Part II is a review of design coordination from an operational perspective

    This article discusses the evolution of a “DistRibuted Agile Methodology Addressing Technical Ictd in Commercial Settings” (DRAMATICS) that was developed in a global software corporation to support ICTD projects from initial team setup through ICT system design, development, and prototyping, to scaling up and transitioning, to sustainable commercial models. We developed the methodology using an iterative Action Research approach in a series of commercial ICTD projects over a period of more than six years. Our learning is reflected in distinctive methodology features that support the development of contextually adapted ICT systems, collaboration with local partners, involvement of end users in design, and the transition from research prototypes to scalable, long-term solutions. We offer DRAMATICS as an approach that others can appropriate and adapt to their particular project contexts. We report on the methodology evolution and provide evidence of its effectiveness in the projects where it has been used

    From skepticism to mutual support: towards a structural change in the relations between participatory budgeting and the information and communication technologies?

    Until three years ago, ICT Technologies represented a main “subordinate clause” within the “grammar” of Participatory Budgeting (PB), the tool made famous by the experience of Porto Alegre and today expanded to more than 1400 cities across the planet. In fact, PB – born to enhance deliberation and exchanges among citizens and local institutions – has long looked at ICTS as a sort of “pollution factor” which could be useful to foster transparency and to support the spreading of information but could also lead to a lowering in quality of public discussion, turning its “instantaneity” into “immediatism,” and its “time-saving accessibility” into “reductionism” and laziness in facing the complexity of public decision-making through citizens’ participation. At the same time, ICTs often regarded Participatory Budgeting as a tool that was too-complex and too-charged with ideology to cooperate with. But in the last three years, the barriers which prevented ICTs and Participatory Budgeting to establish a constructive dialogue started to shrink thanks to several experiences which demonstrated that technologies can help overcome some “cognitive injustices” if not just used as a means to “make simpler” the organization of participatory processes and to bring “larger numbers” of intervenients to the process. In fact, ICTs could be valorized as a space adding “diversity” to the processes and increasing outreach capacity. Paradoxically, the experiences helping to overcome the mutual skepticism between ICTs and PB did not come from the centre of the Global North, but were implemented in peripheral or semiperipheral countries (Democratic Republic of Congo, Brazil, Dominican Republic and Portugal in Europe), sometimes in cities where the “digital divide” is still high (at least in terms of Internet connections) and a significant part of the population lives in informal settlements and/or areas with low indicators of “connection.” Somehow, these experiences were able to demystify the “scary monolithicism” of ICTs, showing that some instruments (like mobile phones, and especially the use of SMS text messaging) could grant a higher degree of connectivity, diffusion and accountability, while other dimensions (which could risk jeopardizing social inclusion) could be minimized through creativity. The paper tries to depict a possible panorama of collaboration for the near future, starting from descriptions of some of the above mentioned “turning-point” experiences – both in the Global North as well as in the Global South

    Agents in Bioinformatics

    The scope of the Technical Forum Group (TFG) on Agents in Bioinformatics (BIOAGENTS) was to inspire collaboration between the agent and bioinformatics communities with the aim of creating an opportunity to propose a different (agent-based) approach to the development of computational frameworks both for data analysis in bioinformatics and for system modelling in computational biology. During the day, the participants examined the future of research on agents in bioinformatics primarily through 12 invited talks selected to cover the most relevant topics. From the discussions, it became clear that there are many perspectives to the field, ranging from bio-conceptual languages for agent-based simulation, to the definition of bio-ontology-based declarative languages for use by information agents, and to the use of Grid agents, each of which requires further exploration. The interactions between participants encouraged the development of applications that describe a way of creating agent-based simulation models of biological systems, starting from an hypothesis and inferring new knowledge (or relations) by mining and analysing the huge amount of public biological data. In this report we summarise and reflect on the presentations and discussions

    Designing as Construction of Representations: A Dynamic Viewpoint in Cognitive Design Research

    Get PDF
    This article presents a cognitively oriented viewpoint on design. It focuses on cognitive, dynamic aspects of real design, i.e., the actual cognitive activity implemented by designers during their work on professional design projects. Rather than conceiving de-signing as problem solving - Simon's symbolic information processing (SIP) approach - or as a reflective practice or some other form of situated activity - the situativity (SIT) approach - we consider that, from a cognitive viewpoint, designing is most appropriately characterised as a construction of representations. After a critical discussion of the SIP and SIT approaches to design, we present our view-point. This presentation concerns the evolving nature of representations regarding levels of abstraction and degrees of precision, the function of external representations, and specific qualities of representation in collective design. Designing is described at three levels: the organisation of the activity, its strategies, and its design-representation construction activities (different ways to generate, trans-form, and evaluate representations). Even if we adopt a "generic design" stance, we claim that design can take different forms depending on the nature of the artefact, and we propose some candidates for dimensions that allow a distinction to be made between these forms of design. We discuss the potential specificity of HCI design, and the lack of cognitive design research occupied with the quality of design. We close our discussion of representational structures and activities by an outline of some directions regarding their functional linkages

    Computational intelligence based complex adaptive system-of-systems architecture evolution strategy

    The dynamic planning for a system-of-systems (SoS) is a challenging endeavor. Large scale organizations and operations constantly face challenges to incorporate new systems and upgrade existing systems over a period of time under threats, constrained budget and uncertainty. It is therefore necessary for the program managers to be able to look at the future scenarios and critically assess the impact of technology and stakeholder changes. Managers and engineers are always looking for options that signify affordable acquisition selections and lessen the cycle time for early acquisition and new technology addition. This research helps in analyzing sequential decisions in an evolving SoS architecture based on the wave model through three key features namely; meta-architecture generation, architecture assessment and architecture implementation. Meta-architectures are generated using evolutionary algorithms and assessed using type II fuzzy nets. The approach can accommodate diverse stakeholder views and convert them to key performance parameters (KPP) and use them for architecture assessment. On the other hand, it is not possible to implement such architecture without persuading the systems to participate into the meta-architecture. To address this issue a negotiation model is proposed which helps the SoS manger to adapt his strategy based on system owners behavior. This work helps in capturing the varied differences in the resources required by systems to prepare for participation. The viewpoints of multiple stakeholders are aggregated to assess the overall mission effectiveness of the overarching objective. An SAR SoS example problem illustrates application of the method. Also a dynamic programing approach can be used for generating meta-architectures based on the wave model. --Abstract, page iii
