  • Understanding and improving chemotherapy ordering and delivery using Process elicitation and validation.
    Journal of Clinical Oncology, 2012
    Co-Authors: Wilson C. Mertens, Stefan C. Christov, Lucinda Cassells, Leon J. Osterweil, Lori A. Clarke, George S. Avrunin, Jenna L. Marquard
    Abstract:

    89 Background: Chemotherapy order/administration consists of complex, interrelated Processes where errors have potentially severe consequences. We report a study that quantitatively and qualitatively evaluated chemotherapy delivery employing a formal Process Definition language to elicit and describe rigorously the Process, then applied mathematical validation techniques to confirm the description, analogously to how computer software development and other industries use accurate, precise Process Definitions to assure soundness through redundancy and correct event sequencing. Methods: The Process, including exceptional situations and individuals’ recognition of and responses to these, was elicited through informal, unstructured interviews with members of an interdisciplinary team. The resulting Process description (or Process Definition), written in a notation developed for software development Process assessment, guided chemotherapy Process validation consisting of rigorous Process Definition analysis, d...

  • Business Process Management Workshops - Challenges observed in the Definition of reference business Processes
    Business Process Management Workshops, 2007
    Co-Authors: Liming Zhu, Leon J. Osterweil, Mark Staples, Udo Kannengiesser
    Abstract:

    In many modern enterprises, explicit business Process Definitions facilitate the pursuit of business goals in such ways as best practice reuse, Process analysis, Process efficiency improvement, and automation. Most real-world business Processes are large and complex. Successfully capturing, analysing, and automating these Processes requires Process Definition languages that capture a variety of Process aspects with a wealth of details. Most current Process modeling languages, such as Business Process Modeling Notation (BPMN), focus on structural control flows among activities while providing inadequate support for other Process Definition needs. In this paper, we first illustrate these inadequacies through our experiences with a collection of real-world reference business Processes from the Australian lending industry. We observe that the most significant inadequacies include lack of resource management, exception handling, Process variation, and data flow integration. These identified shortcomings led us to consider the Little-JIL language as a vehicle for defining business Processes. Little-JIL addresses the aforementioned inadequacies with a number of innovative features. Our investigation concludes that these innovative features are effective in addressing a number of key reference business Process Definition needs.

  • DG.O - Using Process Definitions to drive user interactions with digital government systems
    2007
    Co-Authors: Lori A. Clarke, Leon J. Osterweil, Norman Sondheimer, Alan Gaitenby, Ethan Katsh, Matthew Marzilli, Daniel Rainey, Borislava I. Simidchieva, Leah Wing, Alexander Wise
    Abstract:

    This poster is showing that Process Definitions can be effective in specifying and guiding Online Dispute Resolution (ODR) to facilitate effective interactions and mediation among disputants. Simply specifying these interactions is not sufficient to assure that the mediator and the participants are effectively engaged in performing their roles in such Processes. Our project is developing a system to translate Process Definition specifications into actions that are reflected in the screens that participants and mediators view while participating in these Processes. Thus we are demonstrating that, with the help of the system we are building, the Process Definition can control changes to the user interfaces of the participants involved in the Process itself. This should enable the Process to keep all users continually informed about the state of the Process in which they are participating including the actions that the user needs to perform. This should improve the ability of the Process to be an effective aid to ODR mediation.

  • ISPW - Process Definition language support for rapid simulation prototyping
    Unifying the Software Process Spectrum, 2006
    Co-Authors: Mohammad Raunak, Leon J. Osterweil
    Abstract:

    This paper suggests how an appropriately designed and architected Process Definition language can be an effective aid to the rapid generation of simulations, which are, in turn, capable of providing important insights. The paper describes how the features of the Little-JIL Process Definition language helped in the rapid generation of simulations that shed important new light on the effectiveness of various collusion strategies in influencing the outcomes of various auction approaches. The paper describes how Little-JIL’s approach to modular reuse and its separation of Process concerns both turn out to be of particular value in supporting rapid prototyping. The simulation results obtained are themselves interesting, as the paper also suggests that the auction idiom is highly relevant to resource allocation in software development. Thus, the insights gained into the efficacy of various collusion approaches have particular relevance to software Process research.

  • Analyzing Processes for E-Government Application Development: The Emergence of Process Definition Languages
    Journal of E-Government, 2005
    Co-Authors: Leon J. Osterweil, Charles M. Schweik, Norman Sondheimer, Craig W. Thomas
    Abstract:

    Abstract E-government developers need to clearly understand Processes they are automating and ensure that automated Processes are defect-free. This paper introduces readers to Process Definition Language (PDL) technology that provides rigor and precision over traditional forms of Process documentation. We report our experience documenting license renewal Processes for application in the Mass.gov portal. The PDL helped analysts identify inconsistencies and errors in natural language-based documents that were guiding system development. This case provides an initial demonstration of the benefits PDLs can bring to e-government application development. We conclude with a discussion of the current limitations of PDLs and a discussion of computer-based analysis approaches that will likely emerge in the future.

  • Process Definition and project tracking in model driven engineering
    Lecture Notes in Computer Science, 2006
    Co-Authors: Ivan Porres, Maria C Valiente
    Abstract:

    This paper presents a software Process Definition language that is targeted towards the development of software and systems using Model Driven Engineering methods. The dynamics of a Process model are based on Petri Nets. This allows us to use a Process Definition model to plan and track the execution of actual projects. This new language can be integrated with existing approaches for software Process modeling such as Software Process Engineering Metamodel.

  • Workflow Process Definition tool based on reuse-PDTBR
    Journal of Computer Applications, 2009
    Co-Authors: Hao Ke-gang
    Abstract:

    An approach to define workflow Process on the basis of reuse was proposed in order to improve its efficiency. The Process for producing and describing the reusable assets, domain business ontology and workflow template were presented here. Moreover, a workflow template retrieval method based on domain business ontology was stated. A reuse-based Process Definition tool was developed as a result. It has demonstrated that the approach is feasible and more productive in application.

  • Research and Application of an XML-based Workflow Process Definition Language
    Computer Engineering, 2005
    Co-Authors: Liu Hai-ling
    Abstract:

    This paper presentes an XML-based workflow Definition language named XML-WfPDL to describe the workflow Process model,deriving from the advantages of the XPDL of WfMC and XML. This language separates workflow Process Definition from workflow executionengine, so it may make the workflow Definition language flexible enough to adapt to web and the heterogeneous application environment. And then,it also introduces design idea, main concept and related realization technology of XML-WfPDL. At last, it gives an example of a networkexamination and approval system based on XML-WfPDL.
