Message Management Systems: Concepts, Motivations, and Strategic Effects

This paper motivates the need for system-level message management software. It begins by considering information flows in the workplace as a source of potential gains in efficiency. We next investigate work-flow automation and electronic data interchange (EDI) as indicative of current technologies applied to work processes and message management. Having described current technology and our vision of work processes, we propose an alternative, general-purpose, software technology for supporting application-to-application communication. Problems of EDI, of process-to-process communication, and of describing information items are discussed in terms of the communication problems they present. We then justify the need for this kind of software and layout the criteria (or plausibility conditions) for evaluating a proposal for this sort of system software. The use of a formal communication language is proposed as a common solution to these problems. This proposal is examined in the context of the EDI problem, in order to demonstrate how the proposal might work in practice. Practical benefits of the proposal are discussed that highlight the impact such a technology might have on business practices. The proposed solution is measured against the plausibility conditions presented earlier in the paper; it is found to be sufficient in some cases and in need of further investigation in others. We then discuss the industrial-organizational implications of the availability of such a technology, and hypothesize that it would affect the number and form of cooperative business relationships as well as their scope and depth. We also hypothesize that it would provide advantages to those firms that quickly adopt the technology

From Artefacts to Infrastructures

In their initial articulation of the direction of the CSCW field, scholars advanced an open-ended agenda. This continuing commitment to open-ness to different contexts and approaches is not, however, reflected in the contents of the major CSCW outlets. The field appears to privilege particular forms of cooperative work. We find many examples of what could be described as ‘localist studies’, restricted to particular settings and timeframes. This focus on the ‘here and now’ is particularly problematic when one considers the kinds of large-scale, integrated and interconnected workplace information technologies—or what we are calling Information Infrastructures—increasingly found within and across organisations today. CSCW appears unable (or unwilling) to grapple with these technologies—which were at the outset envisaged as falling within the scope of the field. Our paper hopes to facilitate greater CSCW attention to Information Infrastructures through offering a re-conceptualisation of the role and nature of ‘design’. Design within an Information Infrastructures perspective needs to accommodate non-local constraints. We discuss two such forms of constraint: standardisation (how local fitting entails unfitting at other sites) and embeddedness (the entanglement of one technology with other apparently unrelated ones). We illustrate these themes through introducing case material drawn on from a number of previous studies

Users as Designers of Information Infrastructures and the Role of Generativity

The user role in the design of information systems is increasingly portrayed as active and complex, and the relationships between users and developers are portrayed as blurry. Information systems have become ubiquitous in most work processes, and users typically rely on several large scale information systems tightly integrated into other information systems, machines and work practices. In this paper we propose the notion of generativity as a framework to assess generative socio-technical characteristics of such systems, conceptualized as information infrastructures. Further, the paper will discuss the role these characteristics play in users’ involvement by exploring the ways in which users can contribute as designers and thereby expand on the conceptual views of users and design processes of generative information infrastructures. Empirically, this paper presents the evolution of an information system for cooperation between general practice and hospital laboratories, where users in both settings participated in the design process. The system was designed using agile methods, and design and implementation were continuous and iterative co-existing processes. The case showed that a high degree of generativity in the system itself is a necessary condition for users to make changes. However, in an integrated and complex setting the flexibility of the existing and integrated systems will heavily influence the possibility to make changes. The paper also provides an in-depth illustration of how user and designer roles evolve together with circumstances and relationships. However, we argue that this type of evolvement requires dedicating a considerable amount of time and effort to achieve a climate in which such evolvement can take place. Finally, design is more than just the development of technology. It is also the development of work practices in which users’ contributions are decisive. Designing work practices alongside the design of the technology has given rise to insights that feed directly into the design process. Acknowledging users’ substantial contributions in design processes can aid in refining conceptualizations of users and developers along with bolstering efforts to facilitate appropriate user involvement

Unified Behavior Framework for Discrete Event Simulation Systems

Intelligent agents provide simulations a means to add lifelike behavior in place of manned entities. Generally when developed, a single intelligent agent model is chosen, such as rule based, behavior trees, etc. This choice introduces restrictions into what behaviors agents can manifest, and can require significant testing in edge cases. This thesis presents the use of the UBF in the AFSIM environment. The UBF provides the flexibility to implement any and all intelligent agent models, allowing the developer to choose the model he/she feels best fits the experiment at hand. Furthermore, the UBF demonstrates several key software engineering principles through its modular design, including scalability through reduced code complexity, simplified development and testing through abstraction, and the promotion of code reuse

BEHAVIORAL COMPOSITION FOR HETEROGENEOUS SWARMS

Research into swarm robotics has produced a robust library of swarm behaviors that excel at defined tasks such as flocking and area search, many of which have potential for application to a wide range of military problems. However, to be successfully applied to an operational environment, swarms must be flexible enough to achieve a wide array of specific objectives and usable enough to be configured and employed by lay operators. This research explored the use of the Mission-based Architecture for Swarm Composability (MASC) to develop mission-specific tactics as compositions of more general, reusable plays for use with the Advanced Robotic Systems Engineering Laboratory (ARSENL) swarm system. Three tactics were developed to conduct autonomous search of a geographic area and investigation of generated contacts of interest. The tactics were tested in live-flight and virtual environment experiments and compared to a preexisting monolithic behavior implementation completing the same task. Measures of performance were defined and observed that verified the effectiveness of solutions and confirmed the advantages that composition provides with respect to reusability and rapid development of increasingly complex behaviors.Lieutenant Commander, United States NavyApproved for public release.
