Astract: Workflow technology promises an increase in efficiency in the execution of business processes. The technology is widely accepted, but often the high costs exceed the promised benefits. This is due to the fact that companies do not carefully select the business processes for automation by workflow management systems (WFMS). They also implement processes that have an unappropriate structures for automation and/or that are economically irrelevant. This paper presents an evaluation framework that enables a selection of appropriate business processes. Currently there does not exist any suitable evaluation framework. The framework considers criteria for technical feasibility, economic potential and organizational aspects. The scoring model based on these criteria follows a multi factor analysis and leads to a process-automation portfolio enabling the selection of appropriate business processes. The framework has been successfully used in the IT company of an banking corporation.

Astract: The United Nation's Center for Trade Facilitation and Electronic Business (UN/CEFACT) is a standardization body known for its work on UN/EDIFACT and ebXML. One of its most recent developments is UN/CEFACT's Modeling Methodology (UMM). The UMM standard is used to model inter-organizational business processes in the B2B domain. With the increasing availability of electronic governmental services over networks, the frontier between B2B and B2G/G2G disappears. Today one expects a governmental institution to react like any other business partner. Therefore also governments now face the interoperability and compatibility issues as regular businesses do. In order to allow two governmental institutions to collaborate, a methodology uniquely depicting the inter-organizational process from a global perspective is needed. In this paper we propose to use UN/CEFACT's Modeling Methodology in the eGovernment domain. UMM allows the definition of a global choreography which is then being used to derive local orchestrations for each business partner. Such orchestrations can then be used by enterprise applications in a service oriented context. As an example, a real-world scenario from the waste transport domain within the European Union will be shown. Furthermore the possible integration in the context of the We-Go project [3] is examined.

Keywords:
Astract: UN/CEFACT's modeling methodology (UMM) is a UML profile for modeling global B2B choreographies. The current UMM version comprises three main views for describing a computation independent model from a neutral perspective. Currently, the UMM version is missing a platform independent model showing how each partner has to realize the message exchanges to support the agreed choreography. In this paper we derive such a platform independent model from a UMM business transaction - a key artifact of the computation independent model. The resulting model is based on a state machine describing the local view of a participating business partner. This state machine unambiguously defines how a business partner has to react on incoming messages and on message expected but not received.

A UML Profile for Core Components and their Transformation to XSD

Keywords:
Astract: In business-to-business e-commerce, traditional electronic data interchange (EDI) approaches such as UN/EDIFACT have been superseded by approaches like web services and ebXML. Nevertheless, a precise and common semantic definition of business documents exchanged is needed. In order to become independent from a transfer syntax, we prefer defining the documents as platform independent models. An approach that follows this idea is the UN/CEFACT's core component standard. Core components are reusable semantic building blocks which can be combined in various ways to create shared libraries of interoperable business documents. In order to use standard UML modeling tools we have developed a UML profile for the core components standard. Furthermore, we adapt the UN/CEFACT naming and design rules for the UML profile in order to derive XML schemas for business document exchanges. The overall approach is demonstrated by using a specific example from the field of eCommerce.
