The process workgroup was given the task of studying the production process workflow in cooperative (virtual) enterprises, such as large software houses or companies needing concurrent engineering methods, e.g., for designing and making industrial products. We initiated our agenda by studying the main requirements of tools and environments which could entitle them to support production processes. In our vision, the main tools for supporting process design are descriptive notations for process modeling. Such notations should be formal, to help in understanding, analysing, and simulating the process models we describe. Our requirements for the environment were more vague: we envision an environment distributed on heterogeneous hardware, with a rich infrastructure of services, like distributed object databases and hypertext browsers like the WWW. More important, the environment should be able to "understand" the process model to be supported and enacted, i.e., it should be able to reconfigure itself, possibly dynamically, to support and enforce ("enact") the workflow defined by the process model. The agenda we discussed included a survey of existing tools and notations for process modeling, which we summarize, an overview of research trends in the recent past, is outlined and, finally, a study of interesting scenarios and case studies worthy of being explored in the near future is discussed.

Product development has increasingly become a cooperative endeavor that requires effective coordination in the face of complex dependencies over agents, time and functional perspectives. Distinct coordination support technologies have emerged for each of these kinds of distribution, but all face important limitations. This paper presents a unified model of concurrent engineering coordination that synergistically combines existing approaches in a way that avoids many of their individual limitations and combines their strengths. This model is based on an inclusive dependency capture language plus core coordination services for dependency capture, process enactment and exception handling. An initial implementation of this model is presented and challenges for future evolution of this technology are identified.

The paper presents our preliminary exploration into an organisation ontology for the TOVE enterprise model. The ontology puts forward a number of conceptualizations for modeling organisations: agents, roles, positions, goals, communication, authority, commitment. Its primary focus has been in linking structure and behaviour through the concept of empowerment. Empowerment is the right of an organisation agent to perform status changing actions. This linkage is critical to the unification of enterprise models and their executability.

The Annotated Egret Navigator (AEN) is a system designed to support strong collaboration among a group as they cooperatively build, review, revise, and improve a structured hypertext document. AEN was used as the central instructional and research system for a graduate seminar on collaborative systems at the University of Hawaii during Fall, 1994. AEN was used for over 285 hours during the second half of the semester alone, and users generated over 800 nodes and 800 links. Lessons learned about strong collaboration include: (1) Users as well as artifacts should be visible; (2) Provide direct and indirect authoring mechanisms; (3) Provide context-sensitive change information; (4) Provide access to intermediate work products; (5) Maintain database integrity; (6) An agent-based architecture may be necessary for systems supporting strong collaboration; and (7) The WWW is not effective for strong collaboration.

The paper describes the access to a database of prosthetic parts using an information sharing system. The prosthetic parts modeled are made of ceramic materials. The prosthetic parts are a femoral head, a cup, and a cup and head device. The information about the prosthetic parts is based on a feature based model and is stored in a relational database. The model for the information sharing system is object oriented. The relational database is accessed remotely from the object oriented model using gateways.

We demonstrate the advantages of a distributed collaborative system for CSCW and highlight the requirements of brokered support for such a system. We also demonstrate how we have augmented the infrastructure of a prototype CSCW environment called SHASTRA to accommodate brokered collaboration. Several applications and possible scenarios of CSCW with brokered cooperative system are also presented. We describe how brokers can be used to exploit plurality and commonality of tasks in a cooperative setting, improving performance for the entire system.

The aim of current mobile computing systems is to hide the network as far as possible from applications. This paper introduces location aware computing which makes details of the networked computing environment explicitly available to applications. Depending upon where a user is located, and the capabilities of the machines around a user, applications will alter their behaviour. This will automate tasks such as logging-on, screen-locking and telephone re-routing and applications will automatically modify themselves to make best use of a user's computing environment. It is argued that a location aware computing system must address the three main issues of information gathering, data structure and querying and access control. Ideas within these areas are introduced and explained and the concepts of co-location and spheres of influence suggested as paradigms of person-machine interaction.

We present the details of a product prototype we are building to support collaboration and resource discovery in product development efforts. McRDS consists of a framework that integrates CAD, CAE, and office automation tools over various networking infrastructures (Internet, CORBA, etc.). Additionally, it consists of a resource discovery system which is a virtual database, whose data is physically distributed worldwide among heterogeneous product information databases. The collaboration framework supports semantic messaging and information brokering while the information discovery system performs semantic unification in order to respond to queries submitted by users. We use Knowledge Query Manipulation Language (KQML) as the information messaging protocol and PDES/STEP application protocols to express the content of these messages.

Software performance engineering is a software engineering methodology whose scope is continuing performance IV&V during the life cycle. SPEED (Software Performance Evaluation and Modeling) is a toolkit for software performance IV&V according to performance engineering criteria. It is in course of development at the Laboratory for Computer Science, and CERTIA Research Center University of Rome at TorVergata. In its present version, it generates and evaluates the Master Model of the product, a performance analysis model that continuously evolves with the product design, and that includes the software workload model and the abstract machine model, or model of the executing environment. Conventional analytical and hybrid simulation techniques can then be applied to the MM to obtain performance predictions for the product under design. The paper gives a description of the SPEED philosophy and architecture, with an accompanying application example of DBMS performance design.

The TOVE Quality Ontology is the formal representation (using first-order logic) of terms, relationships, and axioms about quality which are generic beyond any specific quality domain. The assumption that quality is "conformance to requirements" is used to decompose the domain of quality into sub-domains of measurement, quality analysis, identification, and traceability. An ontological engineering methodology of posing ontological scope, stating competency questions, constructing data models and axioms, and visualization of the answering of competency questions is demonstrated with an example from the engineering of the traceability ontology.
