Abstract

Purpose

The paper aims to study realization requirements for the flexible enactment of artifact-centric business processes in a dynamic, collaborative environment and to develop a workflow execution framework that can effectively address those requirements.

Design/methodology/approach

This study proposed a framework and contract-based, event-driven architecture design and implementation that can directly realize collaborative artifact-centric business processes in service-oriented architecture (SOA) without any model conversion.

Findings

The results show that the approach is feasible in presenting several key benefits over the use of existing workflow systems to run artifact-centric processes.

Originality/value

Most of the existing approaches require an artifact-centric model to be transformed into executable workflow languages to run on existing workflow management systems. This study argues that the model conversion can incur losses of information and affect traceability and monitoring ability of workflows, especially in an SOA where a workflow can span across multiple inter-business entities.

Abstract

Purpose

In the last decade, bureaucratic organizational hierarchies have been increasingly replaced with flatter organizational forms, bringing together people from different disciplines to form project teams within and between organizations. Distributed project teams often are self‐configuring networks of mobile and “fixed” people, devices, and applications. They are the natural next step in the evolution of distributed computing, after client‐server, web‐based, and peer‐to‐peer computing. Seeks to show that a newly emerging requirement is to facilitate not just mobility of content (i.e. to support a multitude of devices and connectivity modes) to project members, but also mobility of context (i.e. to provide traceable and continuous support of dynamic relationships between people, artifacts, and business processes).

Design/methodology/approach

The contribution of this paper is to present the design goals, the architecture, and implementation of a system aiming at supporting internet‐enabled workflow and groupware for project teams, enabling traceable and continuous support of associations (relationships) between people, artifacts, and business processes.

Findings

The findings indicate that building internet‐enabled workflow and groupware systems is valuable for virtual teamwork, since they provide a foundation for context‐aware and process‐aware information systems.

Originality/value

This article outlines some foundations of process‐aware collaborative work. Provides an analysis of current workflow and groupware shortcomings in respect of virtual teamwork, outlines the design goals, architecture and an implementation of a system aiming at supporting virtual teams on the internet.

Abstract

Web hosted project spaces offer dedicated collaboration and information sharing functions to dispersed members of design, engineering and manufacturing teams. During the recent dot.com boom these so‐called ‘e‐Project’ services became increasingly popular in the A/E/C (Architecture, Engineering and Construction) industry. This industry has started to refer to these products as ‘project web sites’. Their basic service component is a web enabled ‘information space’ for building teams offered through an Application Service Provider (ASP) business model, and accessible via an Extranet requiring only a standard web browser. An expanding set of web hosted applications is meanwhile included in most products, e.g. for messaging and calendaring, data and document management, design reviews and project management. This paper shows how the functionality of project web sites can be enriched by adding advanced task coordination features. Such features are especially relevant for design management. In particular, the paper deals with the need to support the formation and coordination of spontaneous short‐lived sub‐teams in the course of a project. A crucial element of these ‘self‐appointed’ teams is the need to establish rapid agreement on a shared coordination template for the execution of the task at hand. It will be demonstrated how task templates for that purpose can be defined and managed. The chosen solution serves as a task sensitive filter to the overwhelming amount of documents stored typically on a project web site. The approach will be demonstrated on a daily exercise in academic environments: the abstract and paper review process in the preparation of a conference.

Abstract

Purpose

The purpose of this research is to develop a prototype of agent‐based intelligent workflow system for product design collaboration in a distributed network environment.

Design/methodology/approach

This research separates the collaborative workflow enactment mechanisms from the collaborative workflow building tools for flexible workflow management. Applying the XML/RDF (resource description framework) ontology schema, workflow logic is described in a standard representation. Lastly, a case study in collaborative system‐on‐chip (SoC) design is depicted to demonstrate the agent‐based workflow system for the design collaboration on the web.

Findings

Agent technology can overcome the difficulty of interoperability in cross‐platform, distributed environment with standard RDF data schema. Control and update of workflow functions become flexible and versatile by simply modifying agent reasoning and behaviors.

Research limitations/implications

When business partners want to collaborate, how to integrate agents in different workflows becomes a critical issues.

Practical implications

Agent technology can facilitate design cooperation and teamwork communication in a collaborative, transparent product development environment.

Originality/value

This research establishes generalized flow logic RDF models and an agent‐based intelligent workflow management system, called AWfMS, based on the RDF schema of workflow definition. AWfMS minimizes barriers in the distributed design process and hence increases design cooperations among partners.

Abstract

Purpose

This contribution aims to present the core components of a framework and illustrate the main concepts of a methodology for the systematic design and realization of security‐critical inter‐organizational workflows with a portion of a workflow‐scenario drawn from e‐government. It is additionally shown how the framework can be adapted to incorporate advanced security patterns like the Qualified Signature, which extends the concept of digital signature by requiring a natural person to sign.

Design/methodology/approach

The framework is based on a methodology that focuses on the correct implementation of security‐requirements and consists of a suite of tools that facilitates the cost‐efficient realization and management of decentralized, security‐critical workflows.

Findings

The framework has been prototypically validated through case studies from the healthcare and e‐government sector. Positive results in pilot applications with industrial partners encourage further steps: the set of supported security requirements is continuously extended (e.g. rights delegation, four eyes principle), a testing environment for industrial settings is being implemented, and the requirements for the efficient management of inter‐organizational workflows are being analysed systematically.

Practical implications

The framework caters to the needs of an industrial audience, in need of a cost‐efficient support for the systematic and correct realization of secure, inter‐organizational workflows.

Originality/value

The contribution provides a description of the Sectet framework. It is shown how it can be adapted to incorporate advanced security patterns like the Qualified Signature, which implement a legal requirement specific to e‐government.

Abstract

Purpose

Aims to show that workflow management needs to rethink its basis of discussion in order to meet today's challenges and to provide adequate IT support for heterogeneous workflow networks.

Design/methodology/approach

First, the need for flexibility in relating resources in workflow management is examined in more detail. Second, some approaches to managing workflows in heterogeneous networks are inspected and it is found that all of these improve flexibility on the basis of contracting services. Third, it is elaborated how processing by contract supports decentralized resource management through dynamically interrelating social and technical services driven by a cycle (“wheel”) of execution and monitoring, evaluation and demand, as well as selecting and contracting.

Findings

Conclusions are drawn for systems architecture and implementation to guide the design of internet‐enabled workflow support.

Research limitations/implications

Important questions for the research agenda are: how can one enrich application‐oriented workflow modelling languages in order to describe processes as consisting of heterogeneous services? How should one design and implement workflow engines which enable the turning of the “wheel” with the support of integrating human activities and technical agency as workflow process services?

Practical implications

The idea of processing by contract may lead to new workflow concepts and technology to meet the challenges of an internet economy based on the “pay as you go” principle.

Originality/value

Whereas the workflow paradigm of the past may be phrased as processing by definition, i.e. process execution according to predefined process patterns and resource relations, the idea of processing by contract is suggested, i.e. a mode of process execution driven by recurrent process evaluation and service contracting.

Abstract

Purpose

Service‐oriented architecture is becoming increasingly important for healthcare delivery as it assures seamless integration internally between various teams and departments, and externally between healthcare organizations and their partners. In order to make healthcare more efficient and effective, we need to understand and evaluate its processes, and one way of achieving that is through process modeling. Modeling healthcare processes within a service‐oriented environment opens up new perspectives and raises challenging questions. The purpose of this paper is to investigate one of these questions, namely the suitability of web service orchestration and choreography, two closely related but fundamentally different methodologies for modeling web service‐based healthcare processes.

Design/methodology/approach

The authors use a case‐based approach that first developed a set of 12 features for modeling healthcare processes and then used the features to compare orchestration and choreography for modeling part of the scheduled workflow.

Findings

The findings show that neither methodology can, by itself, meet all healthcare modeling requirements in the context of the case study. The appropriate methodology must be selected after consideration of the specific modeling needs. The authors identified usability, capabilities, and evolution as three key considerations to assist with selection of a methodology for healthcare process modeling. Further, sometimes one method will not meet all modeling needs and hence the authors recommend combining the two methodologies in order to harness the benefits of modeling healthcare processes in a service‐oriented environment.

Originality/value

Although literature exists on process modeling of web services for healthcare, there are no criteria describing necessary features for micro‐level modeling, nor is there a comparison of the two leading service composition methodologies within the healthcare context. This paper provides some necessary formalization for process modeling in healthcare.

Abstract

Purpose

The purpose of this paper is to focus on assessing individuals’ problems in learning groups/teams and should lead to the assessment of the group/team itself as a learning entity.

Design/methodology/approach

In this paper, an extension of the IMS-Learning Design (IMS-LD) meta-model is proposed in order to support the assessment of collaborative activities in e-learning. Besides, the software architecture which consists of a set of components forming a web wizard to create, track and assess the collaborative assessment processes is described as to support that extension of the IMS-LD meta-model.

Findings

With the proposed solution we can: make assessment fairer using individual and collective assessment indicators to assign final scores to learners; make an assessment step by step for better individual and collective monitoring activities; and divide the assessment into lighter phases for the correctors. Consequently, the evaluator will have more detailed information about his/her students and the quality of judgment will be better. This could also be useful for the evaluator in order to plan further examinations.

Research limitations/implications

Further experimentations are necessary to test the effectiveness of the proposed system in order to analyze its performances under a massive usage. In addition, the authors plan to use a survey to collect learners’ opinions to know the effectiveness of the proposal in terms of fairness in the assessment of collaborative activities in an online community.

Originality/value

This paper addresses important issues in the educational area, especially assessment of collaborative activities. In fact, to reduce subjectivity and increase fairness in assessing learners in collaborative work, for example, using the peer assessment, in order to try reducing subjectivity and fairly assessing learners. However, while assessing group work, the same mark is attributed for all group members and authors have concluded that it is not the right approach to make a fair and more objective assessment.

Abstract

Purpose

In the last two decades, a proliferation of business process management (BPM) modeling languages, standards and software systems has given rise to much confusion and obstacles to adoption. Since new BPM languages and notation terminologies were not well defined, duplicate features are common. This paper seeks to make sense of the myriad BPM standards, organising them in a classification framework, and to identify key industry trends.

Design/methodology/approach

An extensive literature review is conducted and relevant BPM notations, languages and standards are referenced against the proposed BPM Standards Classification Framework, which lists each standard's distinct features, strengths and weaknesses.

Findings

The paper is unaware of any classification of BPM languages. An attempt is made to classify BPM languages, standards and notations into four main groups: execution, interchange, graphical, and diagnosis standards. At the present time, there is a lack of established diagnosis standards. It is hoped that such a classification facilitates the meaningful adoption of BPM languages, standards and notations.

Practical implications

The paper differentiates BPM standards, thereby resolving common misconceptions; establishes the need for diagnosis standards; identifies the strengths and limitations of current standards; and highlights current knowledge gaps and future trends. Researchers and practitioners may wish to position their work around this review.

Originality/value

Currently, to the best of one's knowledge, such an overview and such an analysis of BPM standards have not so far been undertaken.

Abstract

Purpose

Collaborative processes are relatively complex and are therefore difficult to handle. Representing the joint processes and capturing the interactions among stakeholders in a structured way are critical to improve the collaboration productivity. This paper aims to present a generic collaborative process model that improves on current approaches by explicitly representing the perspectives of stakeholders and their evolution traversing a work process.

Design/methodology/approach

This approach provides a mechanism to identify the interdependencies among tasks and stakeholders, and realizes collaboration through process management. A web‐based information system using the model to support collaborative process management is also described.

Findings

The research work provides collaboration management systems with the ability to analyze and control the processes through sharing perspectives.

Originality/value

The models and methods described in this paper are an important part of a pervasive, resilient and predictable means for business process management over the internet.
