Integration of BPM systems
New technologies have emerged to support the global economy where for instance suppliers, manufactures and retailers are working together in order to minimise the cost and
maximise efficiency. One of the technologies that has become a buzz word for many businesses is business process management or BPM. A business process comprises activities
and tasks, the resources required to perform each task, and the business rules linking these activities and tasks. The tasks may be performed by human and/or machine actors.
Workflow provides a way of describing the order of execution and the dependent relationships between the constituting activities of short or long running processes.
Workflow allows businesses to capture not only the information but also the processes that transform the information - the process asset (Koulopoulos, T. M., 1995). Applications which involve automated, human-centric and collaborative processes across organisations are
inherently different from one organisation to another. Even within the same organisation but over time, applications are adapted as ongoing change to the business processes is seen as the norm in today’s dynamic business environment. The major difference lies in the specifics of business processes which are changing rapidly in order to match the way in which businesses operate. In this chapter we introduce and discuss Business Process Management (BPM) with a focus on the integration of heterogeneous BPM systems across multiple organisations. We identify the problems and the main challenges not only with regards to technologies but also in the social and cultural context. We also discuss the issues that have arisen in our bid to find the solutions
06291 Abstracts Collection -- The Role of Business Processes in Service-Oriented Architectures
The Dagstuhl seminar on emph{The Role of Business Processes in Service Oriented Architectures}
(Seminar 06291) took place in July 2006 (16.07.2006-21.07.2006 to be precise). The seminar was
attended by more than 40 experts from both academia and industry. Unlike most Dagstuhl seminars
there was a high participation from industry (in particular from organizations developing software,
e.g., IBM, SAP, Microsoft, Google, etc.). The focal point of the seminar was the marriage of
business processes and service oriented architectures. This was reflected by the topics selected by
the participants and their background
A standards-based ICT framework to enable a service-oriented approach to clinical decision support
This research provides evidence that standards based Clinical Decision Support (CDS)
at the point of care is an essential ingredient of electronic healthcare service delivery. A
Service Oriented Architecture (SOA) based solution is explored, that serves as a task
management system to coordinate complex distributed and disparate IT systems,
processes and resources (human and computer) to provide standards based CDS.
This research offers a solution to the challenges in implementing computerised CDS such
as integration with heterogeneous legacy systems. Reuse of components and services to
reduce costs and save time. The benefits of a sharable CDS service that can be reused by
different healthcare practitioners to provide collaborative patient care is demonstrated.
This solution provides orchestration among different services by extracting data from
sources like patient databases, clinical knowledge bases and evidence-based clinical
guidelines (CGs) in order to facilitate multiple CDS requests coming from different
healthcare settings. This architecture aims to aid users at different levels of Healthcare
Delivery Organizations (HCOs) to maintain a CDS repository, along with monitoring and
managing services, thus enabling transparency.
The research employs the Design Science research methodology (DSRM) combined with
The Open Group Architecture Framework (TOGAF), an open source group initiative for
Enterprise Architecture Framework (EAF). DSRM’s iterative capability addresses the
rapidly evolving nature of workflows in healthcare. This SOA based solution uses
standards-based open source technologies and platforms, the latest healthcare standards
by HL7 and OMG, Decision Support Service (DSS) and Retrieve, Update Locate Service
(RLUS) standard. Combining business process management (BPM) technologies,
business rules with SOA ensures the HCO’s capability to manage its processes. This
architectural solution is evaluated by successfully implementing evidence based CGs at
the point of care in areas such as; a) Diagnostics (Chronic Obstructive Disease), b) Urgent
Referral (Lung Cancer), c) Genome testing and integration with CDS in screening
(Lynch’s syndrome). In addition to medical care, the CDS solution can benefit
organizational processes for collaborative care delivery by connecting patients,
physicians and other associated members. This framework facilitates integration of
different types of CDS ideal for the different healthcare processes, enabling sharable CDS
capabilities within and across organizations
Ontology-based patterns for the integration of business processes and enterprise application architectures
Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge
the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture
descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of
software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data.
Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an
ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their
applicability in business process-driven application integration is demonstrated
A Taxonomy of Variability in Web Service Flows
The combination of Software Product Lines (SPL) and Service-Oriented Architectures (SOA) development practices is expected to become a new development paradigm maximizing reuse and business integration. However, multiples issues must be still addressed in order to clarify the connections between both fields. One of the key questions to answer is how SPL practices can be used to support serviceoriented applications. in this context, identifying and managing the points of variability in composite Web services emerges as an inevitable step for making possible such integration. in this position paper we give a first step toward such direction by introducing a comprehensible overview of the main variability points in Web service flows.Ministerio de Educación y Ciencia TIN2006-0047
The Value Proposition of Service-Oriented Architecture
The author of this thesis evaluates Service-Oriented Architecture (SOA) design and implementation strategies. The purpose is to provide the reader with the definition of Service-Oriented Architecture. This report discusses: (1) The definition of Service-Oriented Architecture, (2) The problems solved by Service-Oriented Architecture, (3) Application of design principles to achieve Service-Oriented Architecture. As a result of this investigation, Service-Oriented Architecture is a design style that is fundamentally about sharing and reuse of functionality across diverse applications, so that organizations can quickly adapt to changing business requirements while increasing IT asset reuse and minimizing integration and development costs
Towards a flexible service integration through separation of business rules
Driven by dynamic market demands, enterprises are continuously exploring collaborations with others to add value to their services and seize new market opportunities. Achieving enterprise collaboration is facilitated by Enterprise Application Integration and Business-to-Business approaches that employ architectural paradigms like Service Oriented Architecture and incorporate technological advancements in networking and computing. However, flexibility remains a major challenge related to enterprise collaboration. How can changes in demands and opportunities be reflected in collaboration solutions with minimum time and effort and with maximum reuse of existing applications? This paper proposes an approach towards a more flexible integration of enterprise applications in the context of service mediation. We achieve this by combining goal-based, model-driven and serviceoriented approaches. In particular, we pay special attention to the separation of business rules from the business process of the integration solution. Specifying the requirements as goal models, we separate those parts which are more likely to evolve over time in terms of business rules. These business rules are then made executable by exposing them as Web services and incorporating them into the design of the business process.\ud
Thus, should the business rules change, the business process remains unaffected. Finally, this paper also provides an evaluation of the flexibility of our solution in relation to the current work in business process flexibility research
