A cross-domain workflow application may be constructed using a standard reference model such as the one by the Workflow Management Coalition (WfMC) [7] but the requirements for this type of application are inherently different from one organization to another. The existing models and systems built around them meet some but not all the requirements from all the organizations involved in a collaborative process. Furthermore the requirements change over time. This makes the applications difficult to develop and distribute. Service Oriented Architecture (SOA) based approaches such as the BPET (Business Process Execution Language) intend to provide a solution but fail to address the problems sufficiently, especially in the situations where the expectations and level of skills of the users (e.g. the participants of the processes) in different organisations are likely to be different. In this paper, we discuss a design pattern that provides a novel approach towards a solution. In the solution, business users can design the applications at a high level of abstraction: the use cases and user interactions; the designs are documented and used, together with the data and events captured later that represents the user interactions with the systems, to feed an intermediate component local to the users -the IFM (InterFace Mapper) -which bridges the gaps between the users and the systems. We discuss the main issues faced in the design and prototyping. The approach alleviates the need for re-programming with the APIs to any back-end service thus easing the development and distribution of the applications

Existing Workflow Management Systems (WFMSs) follow a pragmatic approach. They often use a proprietary modelling language with an intuitive graphical layout. However the underlying semantics lack a formal foundation. As a consequence, analysis issues, such as proving correctness i.e. soundness and completeness, and reliable execution are not supported at design level. This project will be using an applied ontology approach by formally defining key terms such as process, sub-process, action/task based on formal temporal theory. Current business process modelling (BPM) standards such as Business Process Modelling Notation (BPMN) and Unified Modelling Language (UML) Activity Diagram (AD) model their constructs with no logical basis. This investigation will contribute to the research and industry by providing a framework that will provide grounding for BPM to reason and represent a correct business process (BP). This is missing in the current BPM domain, and may result in reduction of the design costs and avert the burden of redundant terms used by the current standards. A graphical tool will be introduced which will implement the formal ontology defined in the framework. This new tool can be used both as a modelling tool and at the same time will serve the purpose of validating the model. This research will also fill the existing gap by providing a unified graphical representation to represent a BP in a logically consistent manner for the mainstream modelling standards in the fields of business and IT. A case study will be conducted to analyse a catalogue of existing ‘patient pathways’ i.e. processes, of King’s College Hospital NHS Trust including current performance statistics. Following the application of the framework, a mapping will be conducted, and new performance statistics will be collected. A cost/benefits analysis report will be produced comparing the results of the two approaches.

This study is specifically concerned with the effect of the Enterprise Resource Planning (ERP) on the Business Process Redesign (BPR). Researcher’s experience and the investigation on previous researches imply that BPR and ERP are deeply related to each other and a study to found the mentioned relation further is necessary. In order to elaborate the hypothesis, a case study, in particular Turkish electricity distribution market and the phase of privatization are investigated. Eight companies that have taken part in privatization process and executed BPR serve as cases in this study. During the research, the cases are evaluated through critical success factors on both BPR and ERP. It was seen that combining the ERP Solution features with business processes lead the companies to be successful in ERP and BPR implementation. When the companies’ success and efficiency were compared before and after the ERP implementation, a considerable change was observed in organizational structure. It was spotted that the team composition is important in the success of ERP projects. Additionally, when the ERP is in driver or enabler role, the companies can be considered successful. On the contrary, when the ERP has a neutral role of business processes, the project fails. In conclusion, it can be said that the companies, which have implemented the ERP successfully, have accomplished the goals of the BPR.

La globalización de los mercados, la apertura económica, los tratados de libre comercio y el entorno de competencia exigen empresas y organizaciones que sean capaces de enfrentar su futuro con parámetros de efi ciencia y efi cacia. Las soluciones tecnológicas solicitadas por los clientes para mantener y aprovechar el crecimiento empresarial de largo plazo en gestión, hacen que soluciones como BPM (Business Process Management) apoyen estas condiciones, convirtiendo la gestión de procesos de negocios en una técnica estratégica, que permite generar y controlar “cambios” de forma ágil, oportuna, confi able y de calidad, con miras al logro de los objetivos estratégicos establecidos por dichas empresas. La gestión empresarial ha evolucionado a tal punto que hoy en día se considera que los procesos son un activo fundamental en el desarrollo de toda organización, razón por la cual las empresas deben adaptarlos, optimizarlos e integrarlos, apoyándose en soluciones de negocio conformadas por plataformas, sistemas de información y aplicativos que responden ante los cambios que produce el entorno, facilitan una mayor productividad del empleado y una mayor y mejor colaboración con socios comerciales y clientes de valor, evitando así riesgos innecesarios que disminuyen la rentabilidad y los benefi cios de las mismas. Es por todo esto que muchas de las empresas interesadas en su perdurabilidad a través del tiempo han adoptado soluciones BPM (Business Process Management), cuyo objetivo es la mejora de la eficiencia a través de la gestión sistemática de los procesos de negocio, los cuales deben ser integrales, automatizados, optimizados, monitoreados y documentados de una forma continua, siendo esta una plataforma de soporte en la toma de decisiones gerenciales relacionadas con ciclos del producto más cortos, inteligencia colectiva en la demanda del mercado y reacciones ágiles frente a las fl uctuaciones de los precios.

El objetivo de la presente tesis es establecer un modelo de estructuración financiera para una titularización de flujos futuros que permita a una empresa de business process outsourcing financiarse en el mercado de valores ecuatoriano. A partir de los ingresos generados por prestación de los servicios de la empresa, se establece un modelo de series de tiempo autoregresivo integrado de media móvil (ARIMA) con componente estacional, para la proyección de los flujos de la titularización de flujos futuros. Este modelo permitió establecer tres escenarios: moderado, optimista y pesimista, en base a la proyección y a sus intervalos de confianza. Adicionalmente, para la proyección de los estados financieros se establecieron varios supuestos, los cuales permitieron la proyección del balance general, el estado de resultados y los índices financieros. Se llega a establecer los niveles de costo en el cual incurrirían las empresas si requerirían financiamiento, ya sea con las diferentes alternativas del mercado de valores como son: obligaciones, titularizaciones y acciones, o mediante crédito del sistema financiero.

The construction sector is under growing pressure to increase productivity and improve quality, most notably in reports by Latham (1994, Constructing the Team, HMSO, London) and Egan (1998, Rethinking Construction, HMSO, London). A major problem for construction companies is the lack of project predictability. One method of increasing predictability and delivering increased customer value is through the systematic management of construction processes. However, the industry has no methodological mechanism to assess process capability and prioritise process improvements. Standardized Process Improvement for Construction Enterprises (SPICE) is a research project that is attempting to develop a stepwise process improvement framework for the construction industry, utilizing experience from the software industry, and in particular the Capability Maturity Model (CMM), which has resulted in significant productivity improvements in the software industry. This paper introduces SPICE concepts and presents the results from two case studies conducted on design and build projects. These studies have provided further in-sight into the relevance and accuracy of the framework, as well as its value for the construction sector.

Business process modelling can help an organisation better understand and improve its business processes. Most business process modelling methods adopt a task- or activity-based approach to identifying business processes. Within our work, we use activity theory to categorise elements within organisations as being either human beings, activities or artefacts. Due to the direct relationship between these three elements, an artefact-oriented approach to organisation analysis emerges. Organisational semiotics highlights the ontological dependency between affordances within an organisation. We analyse the ontological dependency between organisational elements, and therefore produce the ontology chart for artefact-oriented business process modelling in order to clarify the relationship between the elements of an organisation. Furthermore, we adopt the techniques from semantic analysis and norm analysis, of organisational semiotics, to develop the artefact-oriented method for business process modelling. The proposed method provides a novel perspective for identifying and analysing business processes, as well as agents and artefacts, as the artefact-oriented perspective demonstrates the fundamental flow of an organisation. The modelling results enable an organisation to understand and model its processes from an artefact perspective, viewing an organisation as a network of artefacts. The information and practice captured and stored in artefact can also be shared and reused between organisations that produce similar artefacts.

Outsourcing decisions are not, technically, irreversible. But in practical terms the organizational disruption and financial costs of bringing services back in house (“backsourcing”) mean that few organizations revert, even when quite dissatisfied with an arrangement. Instead, organizations typically seek to move to another outsourcing arrangement, that is sometimes less attractive than the original in-house delivery. Preliminary evidence from studies of business process outsourcing (BPO) experiences, like those into IT outsourcing’s success, suggests that only a minority of organizations report their BPO arrangements as satisfactory, implying that many are caught in this “can’t go back” bind. In this paper the authors examine two organizations contemplating the adoption of BPO, and consider their expectations and experiences in light of existing empirical literature. The paper concludes with a set of principles to assist organizations to avoid BPO failure.

Business processes especially those in knowledge intensive environments often emerge rather than following predefined steps. Supporting emergent processes is one of the key issues for collaborative knowledge sharing. This paper first introduces a component-based workspace metamodel used to support emergent processes. A loose-coupled collaborative process management model WorkPath is proposed based on the workspace structure to support flexible process evolution management and coordination among processes. Key elements that construct workspace and WorkPath, such as role, action, artifact, workspace and reference relation, are described in detail. An implementation prototype and future work is also discussed at the end of the paper.
