To stay relevant to management decision-making needs, the models need to be based upon suitable metamodels. These metamodels, in turn, need to be properly and continuously maintained. While there exists several methods for metamodel development and maintenance, these typically focus on internal metamodel qualities and metamodel engineering processes, rather than on the actual decision-making needs and their impact on the metamodels used. The present paper employs techniques from information theory and learning classification trees to propose a method for metamodel management based upon the value added by entities and attributes to the decision-making process. This allows for the removal of those metamodel parts that give the least “bang for the bucks” in terms of decision support. The method proposed is illustrated using real data from an ongoing research project on systems modifiability.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125210195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have used business process models as a starting point to derive alternative sets of requirements for a process-oriented system. These alternative sets capture different decisions regarding the intended “level of automation” for the various activities in a business process. The approach is demonstrated in a case study which consists of the development of a real system to manage processes in a Human Resources (HR) Department of a large organization. We use a requirements specification that was previously obtained through what we characterize as a “conventional” requirements engineering technique and we compare it with the requirements specifications derived from the business process model. We discuss the impact of the use of business process models in the completeness, correctness, consistency and traceability of requirements in the case study.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127364416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an MDA-based approach that incorporates behavior modeling at the Platform-Independent Model (PIM) level of the design process of a specific category of applications, i.e., context-aware mobile applications. This approach includes two model transformations. The first transformation is a refinement of the (external) observable application behavior into a (internal) structured behavior based on a reference architecture. The second transformation is the synthesis of this structured behavior into the behavior of individual architecture components. This paper focuses on the second transformation and targets the behavior of a coordinator component that orchestrates the interactions between all the other components. We propose a state machines-based approach that can be used for synthesizing the coordinator component behavior in order to cope with synchronization and concurrency issues.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126500111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts to e-procure goods and services estimated at about 12–25% of GDP from vendors since 1999 is expected to provide significant savings to the government. But the uptake among the vendor community is still less than satisfactory. A study was carried out to examine the organizational context in terms of the suppliers' involvement and perception towards the adoption of the public e-procurement system called “e-Perolehan”. Four main constructs were analyzed namely, organizational leadership, organizational perceived usefulness, organizational perceived ease of use and organizational facilitators involving 502 registered suppliers who are eligible to supply goods and services to the various ministries and federal government agencies. The overall results indicate that organizational perspectives play an important role in ensuring the success rate of adoption and use of e-Perolehan system. However, to achieve greater level of adoption and usage, the government must pursue a dual policy of coercion and persuasive. Incentives and prompt payment to the suppliers and datelines for adoption must not be extended any further as has been the case before.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125657278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges are associated with; lack of implicit knowledge related to the client's functional work processes, inadequate coordination and control mechanisms, and lack of trust across dissimilarities. This paper describes how a vendor's organisational structures have been used to overcome the struggle associated with knowledge sharing in a virtual environment. The vendor has developed workgroup structures involving new boundary roles for building relationships with clients and coordination of project schedules at offshore development sites. Vendor employees located at the client country interpret the implicit knowledge related to the client's functional work processes, which are then translated over a centralised organisational portal to offshore development locations. Regular updates are maintained in the organisational portal to provide information on current project tasks to both clients and distributed team members. English language training is also provided to developers to improve trans-global communications.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114826585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implementing a service-oriented architecture (SOA) promises increasing flexibility as well as agility and decreasing development and maintenance costs of IT landscapes. Simultaneously with these advantages, the implementation of an SOA entails some inherent challenges. The flexible orchestration of services increases the complexity of the whole system significantly and can even result in decreasing performance [1]. A holistic management of technology and business processes is therefore necessary [2]. We believe that the essential SOA management tasks include topics such as strategy, governance, processes as well as infrastructure. These management topics can be addressed on different levels of granularity, e.g. at an SOA governance level or a single service level. This article focuses on individual services and shows how to support their identification and design. Therefore, we present specific deduced dimensions of the generic topics governance and strategy. In addition, we present roles and techniques in order to consider these topics already during the early phases of an SOA implementation, i.e. in the identification and design process.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a need to link these elements to develop e-infrastructures that enable an organization to learn and evolve, be agile and flexible, and adapt to the changing requirements of the highly interconnected environment. While providing flexibility and evolvability we argue that the characteristics of information generated through Web Services and RFID tags enable us to provide services that are also stable and available. The stabilization and convergence of standards for the execution of business processes, Web Services, RFID data enable us to design cyber-infrastructures that resemble the supply chain services they support.

The correctness of composition requires techniques to verify if the composite service behaves properly. To this end, in this paper we propose a new method for runtime monitoring of composite services which uses Communicating Sequential Processes (CSP) to specify properties formally. Then, the CSP specification of properties is translated to a Labeled Transition System (LTS). In order to verify the safety of a composite service, we traverse the generated LTS at runtime. Existing methods almost use temporal logic to specify safety properties. There are two advantages in using CSP: 1) similarity of CSP operators and service composition patterns makes CSP straightforward to be used by users. 2) there are some properties which can not be specified by temporal logic, while they can be expressed using CSP.","PeriodicalId":226791,"journal":{"name":"2009 13th Enterprise Distributed Object Computing Conference Workshops","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134537433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
